Generic Name: Almotriptan malate
Dosage Form: tablet, film coated
Indications and Usage for Almotriptan
Acute Treatment of Migraine Attacks
Almotriptan tablets, USP are indicated for the acute treatment of migraine attacks in patients with a history of migraine with or without aura.
Adolescents Age 12 to 17 Years
Almotriptan tablets, USP are indicated for the acute treatment of migraine headache pain in patients with a history of migraine attacks with or without aura usually lasting 4 hours or more (when untreated).
Almotriptan tablets should only be used where a clear diagnosis of migraine has been established. If a patient has no response for the first migraine attack treated with Almotriptan tablets, the diagnosis of migraine should be reconsidered before Almotriptan tablets are administered to treat any subsequent attacks.
In adolescents age 12 to 17 years, efficacy of Almotriptan tablets on migraine-associated symptoms (nausea, photophobia, and phonophobia) was not established. Almotriptan tablets are not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine [see Contraindications (4.7)].
Safety and effectiveness of Almotriptan tablets have not been established for cluster headache which is present in an older, predominantly male population.
Almotriptan Dosage and Administration
Acute Treatment of Migraine Attacks
The recommended dose of Almotriptan tablets, USP in adults and adolescents age 12 to 17 years is 6.25 mg to 12.5 mg, with the 12.5 mg dose tending to be a more effective dose in adults. As individuals may vary in their response to different doses of Almotriptan tablets, the choice of dose should be made on an individual basis.
If the headache is relieved after the initial Almotriptan tablets dose but returns, the dose may be repeated after 2 hours. The effectiveness of a second dose has not been established in placebo-controlled trials. The maximum daily dose should not exceed 25 mg. The safety of treating an average of more than four migraines in a 30-day period has not been established.
The recommended starting dose of Almotriptan tablets, USP in patients with hepatic impairment is 6.25 mg. The maximum daily dose should not exceed 12.5 mg over a 24-hour period [see Warnings and Precautions (5.9) and Clinical Pharmacology (12.3)].
The recommended starting dose of Almotriptan tablets, USP in patients with severe renal impairment is 6.25 mg. The maximum daily dose should not exceed 12.5 mg over a 24-hour period [see Warnings and Precautions (5.9) and Clinical Pharmacology (12.3)].
Dosage Forms and Strengths
Almotriptan tablets, USP are available as white, circular, biconvex, film-coated tablets in the following dosage strengths:
6.25 mg tablet debossed with ‘A1’ on one side and plain on other side.
12.5 mg tablet debossed with ‘A2’ on one side and plain on other side.
Ischemic or Vasospastic Coronary Artery Disease, or Other Significant Underlying Cardiovascular Disease
Do not use Almotriptan tablets in patients with ischemic heart disease (angina pectoris, history of myocardial infarction, or documented silent ischemia), or in patients who have symptoms or findings consistent with ischemic heart disease, coronary artery vasospasm, including Prinzmetal's variant angina, or other significant underlying cardiovascular disease [see Warnings and Precautions (5.1)].
Do not use Almotriptan tablets in patients with cerebrovascular syndromes including (but not limited to) stroke of any type as well as transient ischemic attacks [see Warnings and Precautions (5.3)].
Peripheral Vascular Disease
Do not use Almotriptan tablets in patients with peripheral vascular disease including (but not limited to) ischemic bowel disease [see Warnings and Precautions (5.4)].
Because Almotriptan tablets may increase blood pressure, do not use Almotriptan tablets in patients with uncontrolled hypertension [see Warnings and Precautions (5.7)].
Ergotamine-Containing and Ergot-Type Medications
Do not use Almotriptan tablets and ergotamine-containing or ergot-derived medications like dihydroergotamine, ergotamine tartrate, or methysergide within 24 hours of each other [see Drug Interactions (7.1)].
Concomitant Use With 5-HT1 Agonists (e.g., Triptans)
Hemiplegic or Basilar Migraine
Do not use Almotriptan tablets in patients with hemiplegic or basilar migraine.
Almotriptan tablets are contraindicated in patients with known hypersensitivity to Almotriptan or any of its inactive ingredients.
Warnings and Precautions
Risk of Myocardial Ischemia and Infarction and Other Adverse Cardiac Events
Cardiac Events and Fatalities with 5-HT1 Agonists
Serious adverse cardiac events, including acute myocardial infarction, have been reported within a few hours following administration of Almotriptan tablets. Life-threatening disturbances of cardiac rhythm and death have been reported within a few hours following the administration of other triptans. Considering the extent of use of triptans in patients with migraine, the incidence of these events is extremely low.
Almotriptan tablets can cause coronary vasospasm; at least one of these events occurred in a patient with no cardiac history and with documented absence of coronary artery disease. Because of the close proximity of the events to use of Almotriptan tablets, a causal relationship cannot be excluded. Patients who experience signs or symptoms suggestive of angina following dosing should be evaluated for the presence of coronary artery disease (CAD) or a predisposition to Prinzmetal’s variant angina before receiving additional doses of medication, and should be monitored electrocardiographically if dosing is resumed and similar symptoms recur.
Premarketing Experience with Almotriptan Tablets in Adults
Among the 3865 subjects/patients who received Almotriptan tablets in premarketing clinical trials, one patient was hospitalized for observation after a scheduled electrocardiogram (ECG) was found to be abnormal (negative T-waves on the left leads) 48 hours after taking a single 6.25 mg dose of Almotriptan. The patient, a 48-year-old female, had previously taken 3 other doses for earlier migraine attacks. Myocardial enzymes at the time of the abnormal ECG were normal. The patient was diagnosed as having had myocardial ischemia and that she had a family history of coronary disease. An ECG performed 2 days later was normal, as was a follow-up coronary angiography. The patient recovered without incident.
Postmarketing Experience with Almotriptan Tablets in Adults
Serious cardiovascular events have been reported in association with the use of Almotriptan tablets. The uncontrolled nature of postmarketing surveillance, however, makes it impossible to definitively determine the proportion of the reported cases that were actually caused by Almotriptan or to reliably assess causation in individual cases [see Adverse Reactions (6.3)].
Patients with Documented Coronary Artery Disease
Because of the potential of this class of compound (5-HT1 agonists) to cause coronary vasospasm, Almotriptan tablets should not be given to patients with documented ischemic or vasospastic coronary artery disease [see Contraindications (4.1)].
Patients with Risk Factors for CAD
It is strongly recommended that Almotriptan tablets not be given to patients in whom unrecognized CAD is predicted by the presence of risk factors (e.g., hypertension, hypercholesterolemia, smoker, obesity, diabetes, strong family history of CAD, female with surgical or physiological menopause, or male over 40 years of age) unless a cardiovascular evaluation provides satisfactory clinical evidence that the patient is reasonably free of coronary artery and ischemic myocardial disease or other significant underlying cardiovascular disease. The sensitivity of cardiac diagnostic procedures to detect cardiovascular disease or predisposition to coronary artery vasospasm is modest, at best. If, during the cardiovascular evaluation, the patient’s medical history, electrocardiographic or other investigations reveal findings indicative of, or consistent with, coronary artery vasospasm or myocardial ischemia, Almotriptan tabletsshould not be administered [see Contraindications (4.1)].
For patients with risk factors predictive of CAD, who are determined to have a satisfactory cardiovascular evaluation, it is strongly recommended that administration of the first dose of Almotriptan tablets take place in the setting of a physician’s office or similar medically staffed and equipped facility unless the patient has previously received Almotriptan tablets. Because cardiac ischemia can occur in the absence of clinical symptoms, consideration should be given to obtaining on the first occasion of use an ECG during the interval immediately following Almotriptan tablets, in these patients with risk factors. It is recommended that patients who are intermittent long-term users of Almotriptan tablets and who have or acquire risk factors predictive of CAD, as described above, undergo periodic interval cardiovascular evaluation as they continue to use Almotriptan tablets.
The systematic approach described above is intended to reduce the likelihood that patients with unrecognized cardiovascular disease will be inadvertently exposed to Almotriptan tablets. The ability of cardiac diagnostic procedures to detect all cardiovascular diseases or predisposition to coronary artery vasospasm is modest at best. Cardiovascular events associated with triptan treatment have occurred in patients with no cardiac history and with documented absence of coronary artery disease.
Sensations of Pain, Tightness, Pressure in the Chest and/or Throat, Neck, and Jaw
As with other 5-HT1 agonists, sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck, and jaw have been reported after treatment with Almotriptan tablets. Because 5-HT1 agonists may cause coronary vasospasm, patients who experience signs or symptoms suggestive of angina following dosing should be evaluated for the presence of CAD or a predisposition to Prinzmetal’s variant angina before receiving additional doses of medication, and should be monitored electrocardiographically if dosing is resumed and similar symptoms occur. Patients shown to have CAD and those with Prinzmetal’s variant angina should not receive 5-HT1 agonists [see Contraindications (4.1) and Warnings and Precautions (5.1)].
Cerebrovascular Events and Fatalities
Cerebral hemorrhage, subarachnoid hemorrhage, stroke, and other cerebrovascular events have been reported in patients treated with other triptans and some events have resulted in fatalities. In a number of cases, it appeared possible that the cerebrovascular events were primary, the triptan having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine, when they were not. As with other acute migraine therapies, before treating headaches in patients not previously diagnosed as migraineurs and in migraineurs who present with atypical symptoms, care should be taken to exclude other potentially serious neurological conditions. It should be noted that patients with migraine may be at increased risk of certain cerebrovascular events (e.g., stroke, hemorrhage, and transient ischemic attack) [see Contraindications (4.2)].
Other Vasospasm-Related Events, Including Peripheral Vascular Ischemia and Colonic Ischemia
Triptans, including Almotriptan tablets, may cause vasospastic reactions other than coronary artery vasospasm, such as peripheral and gastrointestinal vascular ischemia with abdominal pain and bloody diarrhea. Very rare reports of transient and permanent blindness and significant partial vision loss have been reported with the use of triptans. Visual disorders may also be part of a migraine attack. Patients who experience symptoms or signs suggestive of decreased arterial flow following the use of any triptan, such as ischemic bowel syndrome or Raynaud’s syndrome, are candidates for further evaluation [see Contraindications (4.3)].
The development of a potentially life-threatening serotonin syndrome may occur with triptans, including Almotriptan tablets, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs). If concomitant treatment with Almotriptan tablets and an SSRI (e.g., fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram) or SNRI (e.g., venlafaxine, duloxetine) is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases. Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination) and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea) [See Drug Interactions (7.3)].
Medication Overuse Headache
Overuse of acute migraine drugs (e.g., ergotamine, triptans, opioids, or combination of these drugs for 10 or more days per month) may lead to exacerbation of headache (medication overuse headache). Medication overuse headache may present as migraine-like daily headaches or as a marked increase in frequency of migraine attacks. Detoxification of patients, including withdrawal of the overused drugs, and treatment of withdrawal symptoms (which often includes a transient worsening of headache) may be necessary.
Increases in Blood Pressure
As with other triptans, significant elevations in systemic blood pressure have been reported on rare occasions with Almotriptan tablets use in patients with and without a history of hypertension; very rarely these increases in blood pressure have been associated with significant clinical events. Almotriptan tablets are contraindicated in patients with uncontrolled hypertension. [see Contraindications (4.4)]. In normotensive healthy subjects and patients with hypertension controlled by medication, small, but clinically insignificant, increases in mean systolic (0.21 and 4.87 mm Hg, respectively) and diastolic (1.35 and 0.26 mm Hg, respectively) blood pressure relative to placebo were seen over the first 4 hours after oral administration of 12.5 mg of Almotriptan.
An 18% increase in mean pulmonary artery pressure was seen following dosing with another triptan in a study evaluating subjects undergoing cardiac catheterization.
Hypersensitivity to Sulfonamides
Caution should be exercised when prescribing Almotriptan tablets to patients with known hypersensitivity to sulfonamides. The chemical structure of Almotriptan contains a sulfonyl group, which is structurally different from a sulfonamide. Cross-sensitivity to Almotriptan in patients allergic to sulfonamides has not been systematically evaluated.
Impaired Hepatic or Renal Function
Almotriptan tablets should be administered with caution to patients with diseases that may alter the absorption, metabolism, or excretion of drugs, such as those with impaired hepatic or renal function [see Dosage and Administration (2.2), (2.3) and Clinical Pharmacology (12.3)].
Binding to Melanin-Containing Tissues
When pigmented rats were given a single oral dose of 5 mg/kg of radiolabeled Almotriptan, the elimination half-life of radioactivity from the eye was 22 days. This finding suggests that Almotriptan and/or its metabolites may bind to melanin in the eye. Because Almotriptan could accumulate in melanin-rich tissues over time, there is the possibility that it could cause toxicity in these tissues with extended use. However, no adverse retinal effects related to treatment with Almotriptan were noted in a 52-week toxicity study in dogs given up to 12.5 mg/kg/day (resulting in exposure [AUC] to parent drug approximately 20 times that in humans receiving the maximum recommended human dose of 25 mg/day). Although no systematic monitoring of ophthalmologic function was undertaken in clinical trials, and no specific recommendations for ophthalmologic monitoring are offered, prescribers should be aware of the possibility of long-term ophthalmologic effects.
Three male dogs (out of a total of 14 treated) in a 52-week toxicity study of oral Almotriptan developed slight corneal opacities that were noted after 51 weeks, but not after 25 weeks of treatment. The doses at which this occurred were 2, 5, and 12.5 mg/kg/day. The opacity reversed after a 4-week drug-free period in the affected dog treated with the highest dose. Systemic exposure (plasma AUC) to parent drug at 2 mg/kg/day was approximately 2.5 times the exposure in humans receiving the maximum recommended human daily dose of 25 mg. A no-effect dose was not established.
Serious cardiac reactions, including myocardial infarction, have occurred following the use of Almotriptan tablets. These reactions are extremely rare and most have been reported in patients with risk factors predictive of CAD. Reactions reported in association with triptans have included coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia, and ventricular fibrillation [see Contraindications (4.1) and Warnings and Precautions (5.1)].
The following adverse reactions are discussed in more detail in other sections of the labeling:
Risk of Myocardial Ischemia and Infarction and Other Adverse Cardiac Events [see Warnings and Precautions (5.1)]
Sensations of Pain, Tightness, Pressure in the Chest and/or Throat, Neck, and Jaw [see Warnings and Precautions (5.2)]
Cerebrovascular Events and Fatalities [see Warnings and Precautions (5.3)]
Other Vasospasm-Related Events, Including Peripheral Vascular Ischemia and Colonic Ischemia [see Warnings and Precautions (5.4)]
Serotonin Syndrome [see Warnings and Precautions (5.5)]
Increases in Blood Pressure [see Warnings and Precautions (5.7)]
Adverse events were assessed in controlled clinical trials that included 1840 adult patients who received one or two doses of Almotriptan tablets and 386 adult patients who received placebo. The most common adverse reactions during treatment with Almotriptan tablets were nausea, somnolence, headache, paresthesia, and dry mouth. In long-term open-label studies where patients were allowed to treat multiple attacks for up to 1 year, 5% (63 out of 1347 patients) withdrew due to adverse experiences.
Adverse events were assessed in controlled clinical trials that included 362 adolescent patients who received Almotriptan tablets and 172 adolescent patients who received placebo. The most common adverse reactions during treatment with Almotriptan tablets were dizziness, somnolence, headache, paresthesia, nausea, and vomiting. In a long-term, open-label study where patients were allowed to treat multiple attacks for up to 1 year, 2% (10 out of 420 adolescent patients) withdrew due to adverse events.
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.
Commonly-Observed Adverse Reactions in Double-Blind, Placebo-Controlled Almotriptan Tablets Clinical Trials
Table 1 lists the adverse events that occurred in at least 1% of the adult patients treated with Almotriptan tablets, and at an incidence greater than in patients treated with placebo, regardless of drug relationship.

Other Adverse Reactions Observed in Almotriptan Tablets Clinical Trials
In the paragraphs that follow, the frequencies of less commonly reported adverse clinical reactions are presented. The reports include adverse reactions in 5 adult controlled studies and 1 adolescent controlled study. Variability associated with adverse reaction reporting, the terminology used to describe adverse reactions, etc., limit the value of the quantitative frequency estimates provided. Reaction frequencies are calculated as the number of patients who used Almotriptan tablets and reported a reaction divided by the total number of patients exposed to Almotriptan tablets (n=3047, all doses). All reported reactions are included except those already listed in the previous table, those too general to be informative, and those not reasonably associated with the use of the drug. Reactions are further classified within system organ class and enumerated in order of decreasing frequency using the following definitions: frequent adverse reactions are those occurring in 1/100 or more patients, infrequent adverse reactions are those occurring in fewer than 1/100 to 1/1000 patients, and rare adverse reactions are those occurring in fewer than 1/1000 patients.
Body: Frequent: Headache. Infrequent: Abdominal cramp or pain, Asthenia, Chills, Back pain, Chest pain, Neck pain, Fatigue, and Rigid neck. Rare: Fever and Photosensitivity reaction.

The following adverse reactions have been identified during postapproval use of Almotriptan tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Immune System Disorders: Hypersensitivity reactions (including angioedema, anaphylactic reactions and Anaphylactic shock)
Psychiatric Disorders: Confusional state, Restlessness
Nervous System Disorders: Hemiplegia, Hypoesthesia, Seizures

Musculoskeletal, Connective Tissue, and Bone Disorders: Arthralgia, Myalgia, Pain in extremity
Reproductive System and Breast Disorders: Breast pain
General Disorders: Malaise, Peripheral coldness.
These drugs have been reported to cause prolonged vasospastic reactions. Because, in theory, vasospastic effects may be additive, ergotamine-containing or ergot-type medications (like dihydroergotamine, ergotamine tartrate, or methysergide) and Almotriptan tablets should not be used within 24 hours of each other [see Contraindications (4.5)].
5-HT1 Agonists (e.g., Triptans)
Concomitant use of other 5-HT1 agonists (e.g., triptans) within 24 hours of treatment with Almotriptan tablets is contraindicated [see Contraindications (4.6)].
Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors
Cases of life-threatening serotonin syndrome have been reported during combined use of triptans and selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions (5.5), Clinical Pharmacology (12.3)].
Ketoconazole and Other Potent CYP3A4 Inhibitors
Co-administration of Almotriptan and oral ketoconazole, a potent CYP3A4 inhibitor, resulted in an approximately 60% increase in exposure of Almotriptan. Increased exposures to Almotriptan may be expected when Almotriptan is used concomitantly with other potent CYP3A4 inhibitors[see Clinical Pharmacology (12.3)].
In patients concomitantly using potent CYP3A4 inhibitors, the recommended starting dose of Almotriptan tablets is 6.25 mg. The maximum daily dose should not exceed 12.5 mg within a 24-hour period. Concomitant use of Almotriptan tablets and potent CYP3A4 inhibitors should be avoided in patients with renal or hepatic impairment [see Clinical Pharmacology (12.3)].
USE IN SPECIFIC POPULATIONS
Pregnancy Category C
In animal studies, Almotriptan produced developmental toxicity (increased embryolethality and fetal skeletal variations, and decreased offspring body weight) at doses greater than those used clinically. There are no adequate and well-controlled studies in pregnant women; therefore, Almotriptan tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
When Almotriptan (125, 250, 500, or 1000 mg/kg/day) was administered orally to pregnant rats throughout the period of organogenesis, increased incidences of fetal skeletal variations (decreased ossification) were noted at a dose of 250 mg/kg/day or greater and an increase in embryolethality was seen at the highest dose. The no-effect dose for embryo-fetal developmental toxicity in rats (125 mg/kg/day) is approximately 100 times the maximum recommended human dose (MRHD) of 25 mg/day on a body surface area (mg/m2) basis. Similar studies in pregnant rabbits conducted with Almotriptan (oral doses of 5, 20, or 60 mg/kg/day) demonstrated increases in embryolethality at the highest dose. The no-effect dose for embryo-fetal developmental toxicity in rabbits (20 mg/kg/day) is approximately 15 times the MRHD on a mg/m2 basis. When Almotriptan (25, 100, or 400 mg/kg/day) was administered orally to rats throughout the periods of gestation and lactation, gestation length was increased and litter size and offspring body weight were decreased at the highest dose. The decrease in pup weight persisted throughout lactation. The no-effect dose in this study (100 mg/kg/day) is 40 times the MRHD on a mg/m2 basis.
Labor and Delivery
The effect of Almotriptan tablets on labor and delivery in humans is unknown.
It is not known whether Almotriptan is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Almotriptan tablets are administered to a nursing woman. Levels of Almotriptan in rat milk were up to 7 times higher than in rat plasma.
Safety and efficacy of Almotriptan tablets in pediatric patients under the age of 12 years have not been established. The pharmacokinetics, efficacy, and safety of Almotriptan tablets have been evaluated in adolescent patients, age 12 to 17 years [see Clinical Pharmacology (12.3) and Clinical Studies (14.2)].
In a clinical study, Almotriptan tablets 6.25 mg and 12.5 mg were found to be effective for the relief of migraine headache pain in adolescent patients age 12 to 17 years. Efficacy on migraine-associated symptoms (nausea, photophobia, and phonophobia) was not established. The most common adverse reactions (incidence of ≥1%) associated with Almotriptan tablets treatment were dizziness, somnolence, headache, paresthesia, nausea, and vomiting [see Adverse Reactions (6.1)]. The safety and tolerability profile of Almotriptan tablets treatment in adolescents is similar to the profile observed in adults.
Postmarketing experience with other triptans include a limited number of reports that describe pediatric patients who have experienced clinically serious adverse events that are similar in nature to those reported rarely in adults.
Clinical studies of Almotriptan tablets did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger subjects. Clearance of Almotriptan was lower in elderly volunteers than in younger individuals, but there were no observed differences in the safety and tolerability between the two populations [see Clinical Pharmacology (12.3)]. In general, dose selection for an elderly patient should be cautious, usually starting at the low dose, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The recommended dose of Almotriptan tablets for elderly patients with normal renal function for their age is the same as that recommended for younger adults.
The recommended starting dose of Almotriptan tablets in patients with hepatic impairment is 6.25 mg. The maximum daily dose should not exceed 12.5 mg over a 24-hour period [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)].
The recommended starting dose of Almotriptan tablets in patients with severe renal impairment is 6.25 mg. The maximum daily dose should not exceed 12.5 mg over a 24-hour period [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].
Signs and Symptoms
Patients and volunteers receiving single oral doses of 100 to 150 mg of Almotriptan did not experience significant adverse events. Six additional normal volunteers received single oral doses of 200 mg without serious adverse events. During clinical trials with Almotriptan tablets, one patient ingested 62.5 mg in a 5-hour period and another patient ingested 100 mg in a 38-hour period. Neither patient experienced adverse reactions.
Based on the pharmacology of triptans, hypertension or other more serious cardiovascular symptoms could occur after overdosage.
There is no specific antidote to Almotriptan tablets. In cases of severe intoxication, intensive care procedures are recommended, including establishing and maintaining a patent airway, ensuring adequate oxygenation and ventilation, and monitoring and support of the cardiovascular system.
Clinical and electrocardiographic monitoring should be continued for at least 20 hours even if clinical symptoms are not observed.
It is unknown what effect hemodialysis or peritoneal dialysis has on plasma concentrations of Almotriptan.
Almotriptan tablets, USP contain Almotriptan malate USP, a selective 5-hydroxytryptamine1B/1D (5-HT1B/1D) receptor agonist. Almotriptan malate is chemically designated as 1 - [[[3 - [2 - (Dimethylamino)ethyl] - 1H - indol - 5 - yl]methyl]sulfonyl]pyrrolidine(±) - hydroxybutanedioate (1:1), and its structural formula is:
Its empirical formula is C17H25N3O2S-C4H6O5, representing a molecular weight of 469.55. Almotriptan is a white to off-white crystalline powder that is soluble in water. Almotriptan tablets, USP for oral administration contains Almotriptan malate equivalent to 6.25 or 12.5 mg of Almotriptan. Each compressed tablet contains the following inactive ingredients: mannitol, microcrystalline cellulose, povidone, sodium starch glycolate, sodium stearyl fumarate, polyethylene glycols, titanium dioxide and hypromelloses.
Almotriptan - Clinical Pharmacology
Mechanism of Action
Almotriptan binds with high affinity to 5-HT1D, 5-HT1B, and 5-HT1F receptors. Almotriptan has weak affinity for 5-HT1A and 5-HT7 receptors, but has no significant affinity or pharmacological activity at 5-HT2, 5-HT3, 5-HT4, 5-HT6; alpha or beta adrenergic; adenosine (A1, A2); angiotensin (AT1, AT2); dopamine (D1, D2); endothelin (ETA, ETB); or tachykinin (NK1, NK2, NK3) binding sites.
Current theories on the etiology of migraine headache suggest that symptoms are due to local cranial vasodilatation and/or to the release of vasoactive and pro-inflammatory peptides from sensory nerve endings in an activated trigeminal system. The therapeutic activity of Almotriptan in migraine can most likely be attributed to agonist effects at 5-HT1B/1D receptors on the extracerebral, intracranial blood vessels that become dilated during a migraine attack and on nerve terminals in the trigeminal system. Activation of these receptors results in cranial vessel constriction, inhibition of neuropeptide release, and reduced transmission in trigeminal pain pathways.
The absolute bioavailability of Almotriptan is about 70%, with peak plasma levels occurring 1 to 3 hours after administration; food does not affect pharmacokinetics.
Almotriptan is minimally protein bound (approximately 35%) and the mean apparent volume of distribution is approximately 180 to 200 liters.
Almotriptan is metabolized by two major and one minor pathways. Monoamine oxidase (MAO)-mediated oxidative deamination (approximately 27% of the dose), and cytochrome P450-mediated oxidation (approximately 12% of the dose) are the major routes of metabolism, while flavin monooxygenase is the minor route. MAO-A is responsible for the formation of the indoleacetic acid metabolite, whereas cytochrome P450 (3A4 and 2D6) catalyzes the hydroxylation of the pyrrolidine ring to an intermediate that is further oxidized by aldehyde dehydrogenase to the gamma-aminobutyric acid derivative. Both metabolites are inactive.
Almotriptan has a mean half-life of 3 to 4 hours. Almotriptan is eliminated primarily by renal excretion (about 75% of the oral dose), with approximately 40% of an administered dose excreted unchanged in urine. Renal clearance exceeds the glomerular filtration rate by approximately 3-fold, indicating an active mechanism. Approximately 13% of the administered dose is excreted via feces, both unchanged and metabolized.
All drug interaction studies were performed in healthy volunteers using a single 12.5 mg dose of Almotriptan and multiple doses of the other drug.
Monoamine Oxidase Inhibitors
Co-administration of Almotriptan and moclobemide (150 mg twice daily for 8 days) resulted in a 27% decrease in Almotriptan clearance and an increase in Cmax of approximately 6%. No dose adjustment is necessary.
Co-administration of Almotriptan and propranolol (80 mg twice daily for 7 days) resulted in no significant changes in the pharmacokinetics of Almotriptan.
Co-administration of Almotriptan and fluoxetine (60 mg daily for 8 days), a potent inhibitor of CYP2D6, had no effect on Almotriptan clearance, but maximal concentrations of Almotriptan were increased 18%. This difference is not clinically significant.
Co-administration of Almotriptan and verapamil (120 mg sustained-release tablets twice daily for 7 days), an inhibitor of CYP3A4, resulted in a 20% increase in the area under the plasma concentration-time curve, and in a 24% increase in maximal plasma concentrations of Almotriptan. Neither of these changes is clinically significant. No dose adjustment is necessary.
Ketoconazole and Other Potent CYP3A4 Inhibitors
Co-administration of Almotriptan and ketoconazole, a potent CYP3A4 inhibitor, resulted in an approximately 60% increase in exposure of Almotriptan. Increased exposures to Almotriptan may be expected when Almotriptan is used with other potent CYP3A4 inhibitors.
Renal and total clearance, and amount of drug excreted in the urine, were lower in elderly healthy volunteers (age 65 to 76 years) than in younger healthy volunteers (age 19 to 34 years), resulting in longer terminal half-life (3.7 hours vs. 3.2 hours) and a 25% higher area under the plasma concentration-time curve in the elderly subjects. The differences, however, do not appear to be clinically significant.
A pharmacokinetics study of Almotriptan was conducted in adolescents (12 to 17 years) and adults (18 to 55 years) with or without a history of migraine. No differences were observed in the rate or extent of absorption of Almotriptan in adolescents compared with adults.
No significant gender differences were observed in pharmacokinetic parameters.
No significant differences were observed in pharmacokinetic parameters between Caucasian and African-American volunteers.
The pharmacokinetics of Almotriptan have not been assessed in patients with hepatic impairment. Based on the known mechanisms of clearance of Almotriptan, the maximum decrease expected in Almotriptan clearance due to hepatic impairment would be 60% [see Dosage and Administration (2.2)].
The clearance of Almotriptan was approximately 65% lower in patients with severe renal impairment (Cl/F=19.8 L/hour; creatinine clearance between 10 and 30 mL/min) and approximately 40% lower in patients with moderate renal impairment (Cl/F=34.2 L/hour; creatinine clearance between 31 and 71 mL/min) than in healthy volunteers (Cl/F= 57 L/hour). Maximal plasma concentrations of Almotriptan increased by approximately 80% in these patients [see Dosage and Administration (2.3)].
Carcinogenesis, Mutagenesis, Impairment of Fertility
Almotriptan was administered to mice and rats for up to 103-104 weeks at oral doses up to 250 mg/kg/day and 75 mg/kg/day, respectively. These doses were associated with plasma exposures (AUC) to parent drug that were approximately 40 and 80 times, in mice and rats respectively, the plasma AUC in humans at the maximum recommended human dose (MRHD) of 25 mg/day. Because of high mortality rates in both studies, which reached statistical significance in high-dose female mice, all female rats, all male mice, and high-dose female mice were terminated between weeks 96 and 98. There was no increase in tumors related to Almotriptan administration.
Almotriptan was not mutagenic in two in vitro gene mutation assays, the Ames test, and the mouse lymphoma tk assay. Almotriptan was not clastogenic in an in vivo mouse micronucleus assay.
Impairment of Fertility
When male and female rats received Almotriptan (25, 100, or 400 mg/kg/day) orally prior to and during mating and gestation, prolongation of the estrous cycle was observed at the mid-dose and greater, and fertility was impaired at the highest dose. Subsequent mating of treated with untreated animals indicated that the decrease in fertility was due to an effect on females. The no-effect dose for reproductive toxicity in rats (25 mg/kg/day) is approximately 10 times the MRHD on a mg/m2 basis.
The efficacy of Almotriptan tablets was established in three multi-center, randomized, double-blind, placebo-controlled European trials. Patients enrolled in these studies were primarily female (86%) and Caucasian (more than 98%), with a mean age of 41 years (range of 18 to 72). Patients were instructed to treat a moderate to severe migraine headache. Two hours after taking one dose of study medication, patients evaluated their headache pain. If the pain had not decreased in severity to mild or no pain, the patient was allowed to take an escape medication. If the pain had decreased to mild or no pain at 2 hours but subsequently increased in severity between 2 and 24 hours, it was considered a relapse and the patient was instructed to take a second dose of study medication. Associated symptoms of nausea, vomiting, photophobia, and phonophobia were also evaluated.
In these studies, the percentage of patients achieving a response (mild or no pain) 2 hours after treatment was significantly greater in patients who received either Almotriptan tablets 6.25 mg or 12.5 mg, compared with those who received placebo. A higher percentage of patients reported pain relief after treatment with the 12.5 mg dose than with the 6.25 mg dose. Doses greater than 12.5 mg did not lead to a significantly better response. These results are summarized in Table 3.

The estimated probability of achieving pain relief within 2 hours following initial treatment with Almotriptan tablets in adults is shown in Figure 1.

This Kaplan-Meier plot is based on data obtained in the three placebo-controlled clinical trials that provided evidence of efficacy (Studies 1, 2, and 3). Patients not achieving pain relief by 2 hours were censored at 2 hours.
For patients with migraine-associated photophobia, phonophobia, nausea, and vomiting at baseline, there was a decreased incidence of these symptoms following administration of Almotriptan tablets compared with placebo.
Two to 24 hours following the initial dose of study medication, patients were allowed to take an escape medication or a second dose of study medication for pain response. The estimated probability of patients taking escape medication or a second dose of study medication over the 24 hours following the initial dose of study medication is shown in Figure 2.

This Kaplan-Meier plot is based on data obtained in the three placebo-controlled trials that provided evidence of efficacy (Studies 1, 2, and 3). Patients not using additional treatment were censored at 24 hours. Remedication was not allowed within 2 hours after the initial dose of Almotriptan tablets.
The efficacy of Almotriptan tablets was unaffected by the presence of aura; by gender, weight, or age of the patient; or by concomitant use of common migraine prophylactic drugs (e.g., beta-blockers, calcium channel blockers, and tricyclic antidepressants); or oral contraceptives. There were insufficient data to assess the effect of race on efficacy.
Adolescents Age 12 to 17 Years
The efficacy of Almotriptan tablets in adolescent patients age 12 to 17 years was evaluated in a double-blind, randomized, placebo-controlled study. Patients enrolled in that study had at least a 1-year history of migraine attacks with or without aura usually lasting 4 hours or more (when untreated). Patients enrolled in the study were primarily females (60%) and Caucasian (75%), while 15% of patients were black, and 10% were of other races. Patients were instructed to treat a moderate to severe migraine headache. Two hours after taking one dose of study medication, patients evaluated their headache pain. Associated symptoms of nausea, photophobia, and phonophobia were also evaluated.
In this study, the percentage of patients achieving a pain relief response (mild or no pain) 2 hours after treatment was statistically significantly greater in patients who received Almotriptan tablets 6.25 mg or 12.5 mg compared with those who received placebo. There was no additional benefit on pain relief provided by the 12.5 mg dose. The 2-hour pain relief results are summarized in Table 4.

What are Almotriptan tablets and what is it used for?
Almotriptan tablets are medication used to treat migraine attacks in adults and adolescents age 12 to 17 years. Almotriptan tablets are member of a class of drugs called selective serotonin receptor agonists.
Use Almotriptan tablets only for a migraine attack. Do not use Almotriptan tablets to treat headaches that might be caused by other conditions. Tell your doctor about your symptoms. Your doctor will decide if you have migraine.
There is more information about migraine at the end of this leaflet.
Who should not take Almotriptan tablets?*
Do not take Almotriptan tablets if you:
- have ever had heart disease.
- have uncontrolled high blood pressure.
- have hemiplegic or basilar migraine. If you are not sure, ask your doctor.

How should I take Almotriptan tablets?
- When you have a migraine headache, take your medicine as directed by your doctor.
- If your headache comes back after your first dose, you may take a second dose 2 hours or more after the first dose. If your pain continues after the first dose, do not take a second dose without first checking with your doctor.
- Do not take more than two Almotriptan tablets in a 24-hour period.
- Some people who take migraine medicines, like Almotriptan tablets, for 10 or more days every month may have worse headaches (medication overuse headache). If your headaches get worse, your healthcare provider may decide to stop your treatment with Almotriptan tablets.
- If you take too much medicine, contact your doctor, hospital emergency department, or poison control center right away.
What should I avoid while taking Almotriptan tablets?
Check with your doctor before you take any new medicines, including prescription and non-prescription medicines and supplements. There are some medicines that you should not take during the period 24 hours before and 24 hours after taking Almotriptan tablets. Some of them are listed in the section “Who should not take Almotriptan tablets?”
What are the possible side effects of Almotriptan tablets?
The side effects are usually mild and do not last long. The following is not a complete list of side effects. Ask your doctor to tell you about the other side effects.
The most common side effects in adults are:
- Tingling or burning feeling (paresthesia)
- Dry mouth
The most common side effects in adolescents are:
- Tingling or burning feeling (paresthesia)
If you feel dizzy or sleepy, or if you notice any changes in your vision, you should evaluate your ability to perform complex tasks, such as driving or operating heavy machinery.
Tell your doctor about any other symptoms that you develop while taking Almotriptan tablets. If the symptoms continue or worsen, get medical help right away. Also, tell your doctor if you develop any of the following after taking Almotriptan tablets:
- a swollen face, lips, mouth, tongue or throat
- difficulty swallowing or breathing
- an itchy rash (hives).
These may be a sign that you are allergic to the medicine.
In very rare cases, patients taking this class of medicines experience serious heart problems, stroke, or increased blood pressure. Extremely rarely, patients have died. Therefore, tell your doctor right away if you feel tightness, pain, pressure, or heaviness in your chest, throat, neck, or jaw after taking Almotriptan tablets. Do not take Almotriptan tablets again until your doctor has checked you.
Some people may have a reaction called serotonin syndrome, which can be life-threatening, when they use Almotriptan tablets. In particular, this reaction may occur when they use Almotriptan tablets together with certain types of antidepressants known as SSRIs or SNRIs. Symptoms may include mental changes (hallucinations, agitation, or coma), fast heartbeat, changes in blood pressure, high body temperature or sweating, tight muscles, trouble walking, nausea, vomiting, or diarrhea. Call your doctor immediately if you have any of these symptoms after taking Almotriptan tablets.
This is not a complete list of side effects. Talk to your doctor if you develop any symptoms that concern you.
What to do in case of an overdose?
Call your doctor or poison control center or go to the ER.
What is a migraine and how does it differ from other headaches?
A migraine is an intense, throbbing, typically one-sided headache. It often includes nausea, vomiting, sensitivity to light, and sensitivity to sound. The pain and symptoms from a migraine headache may be worse than the pain and symptoms of a common headache.
Some people have visual symptoms before the headache, such as flashing lights or wavy lines, called an aura.
Migraine attacks typically last for hours or, rarely, for more than a day. They can return often. The strength and frequency of migraine attacks may vary.
Based on your symptoms, your doctor will decide whether you have a migraine.
Migraine headaches tend to occur in members of the same family. Both men and women get migraines, but it is more common in women.
What may trigger a migraine attack?
Certain things may trigger migraine attacks in some people. Some of these triggers are:
- certain foods or drinks, such as cheese, chocolate, citrus fruit (oranges, grapefruit, lemons, limes, and others), caffeine, and alcohol.
- a change in behavior, such as too much or too little sleep, missing a meal, or a change in diet.
- hormone changes in women, such as during monthly menstrual periods.
You may be able to prevent migraine attacks or make them come less often if you understand what triggers your attacks. Keeping a headache diary may help you identify and monitor the possible triggers that cause your migraine. Once you identify the triggers, you and your doctor can change your lifestyle to avoid those triggers.
How does Almotriptan tablets work during a migraine attack?
Treatment with Almotriptan tablets:
- reduces swelling of blood vessels surrounding the brain. This swelling is associated with the headache pain of a migraine attack.
- blocks the release of substances from nerve endings that cause more pain and other symptoms of migraine.
- interrupts the sending of specific pain signals to your brain.
It is thought that each of these actions contributes to relief of your symptoms by Almotriptan tablets.
How should I store Almotriptan tablets?
Keep your medicine in a safe place where children cannot reach it. It may be harmful to children. Store your medicine away from heat, light, or moisture at a controlled room temperature. If your medicine has expired, throw it away as instructed. If your doctor decides to stop your treatment, do not keep any leftover medicine unless your doctor tells you to do so. Throw away your medicine as instructed. Be sure that discarded tablets are out of the reach of children.
General advice about prescription medicines
Medicines are sometimes prescribed for conditions that are not mentioned in patient information leaflets. Do not use Almotriptan tablets for a condition for which it was not prescribed. Do not give Almotriptan tablets to other people even if they have the same symptoms you have. People may be harmed if they take medicines that have not been prescribed for them.
This leaflet provides a summary of information about Almotriptan tablets. If you have any questions or concerns about either Almotriptan tablets or migraines, talk to your doctor. In addition, talk to your pharmacist or other healthcare provider.
