Monitor
Phenothiazines, tricyclic antidepressants (TCAs), and some antipsychotic (neuroleptic) agents may potentiate the blood pressure lowering capabilities of other drugs with hypotensive effects due to their peripheral alpha-1 adrenergic blocking activity. Orthostatic hypotension and syncope associated with vasodilation may occur, particularly during initial dosing and/or parenteral administration of the phenothiazine, TCA, or neuroleptic. The severity of this interaction may be affected by the agent's affinity for the alpha-1 adrenoceptor. One in vitro study demonstrated an affinity for the alpha-1 adrenoceptor for some of these medications that was similar to, or greater than, those of alpha blocker medications used to treat hypertension. Examples of drugs evaluated in this study with a high affinity included amitriptyline, clomipramine, chlorpromazine, clozapine, doxepin, flupenthixol, lurasidone, nortriptyline, perphenazine, paliperidone, quetiapine, risperidone, sertindole, and ziprasidone. On the other hand, examples of those with lower affinities included aripiprazole, lofepramine, protriptyline, sulpiride, and amisulpride.
Management
Close clinical monitoring for development of hypotension is recommended if phenothiazines, tricyclic antidepressants (TCAs), or certain antipsychotic (neuroleptic) agents are used in patients receiving antihypertensive medications or vasodilators. A lower starting dosage and slower titration of the phenothiazine, TCA, or neuroleptic may be appropriate, especially in the elderly. It may also be advisable to consider using a phenothiazine, TCA, or neuroleptic medication with a lower affinity for the alpha-1 adrenoceptor when possible. Patients should be counseled to avoid rising abruptly from a sitting or recumbent position and to notify their healthcare provider if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia. Patients should also avoid driving or operating hazardous machinery until they know how the medications affect them.

telmisartan Food/Lifestyle
Applies to: telmisartan
Generally avoid
Moderate-to-high dietary intake of potassium, especially salt substitutes, may increase the risk of hyperkalemia in some patients who are using angiotensin II receptor blockers (ARBs). ARBs can promote hyperkalemia through inhibition of angiotensin II-induced aldosterone secretion. Patients with diabetes, heart failure, dehydration, or renal insufficiency have a greater risk of developing hyperkalemia.
Management
Patients should receive dietary counseling and be advised to not use potassium-containing salt substitutes or over-the-counter potassium supplements without consulting their physician. If salt substitutes are used concurrently, regular monitoring of serum potassium levels is recommended. Patients should also be advised to seek medical attention if they experience symptoms of hyperkalemia such as weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs.

Disease interactions
48 potential interactions Applies to: 38 conditions, including Heart Failure, Seizures, Diarrhea, Breast Cancer, and Hypotension.
Acute Alcohol Intoxication
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Acute Alcohol Intoxication.
The use of most miscellaneous antipsychotics is contraindicated in patients with severe central nervous system depression or comatose states from any cause (e.g., lesion, disease, drug or alcohol induced).
Alcoholism
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Alcoholism.
The use of neuroleptic agents is contraindicated in patients with acute alcohol intoxication exhibiting depressed vital signs. The central nervous system depressant effects of neuroleptic agents may be additive with those of alcohol. Severe respiratory depression and respiratory arrest may occur. Therapy with neuroleptic agents should be administered cautiously in patients who might be prone to acute alcohol intake.
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Alcoholism.
Antipsychotics can lower the seizure threshold and trigger seizures in a dose-dependent manner. Seizures have been reported in patients receiving antipsychotic therapy and may occur in epileptic patients even with maintenance of routine anticonvulsant treatment. Therapy with antipsychotics should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. High dosages should be avoided if possible.
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Alcoholism.
Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.
Altered Consciousness
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Altered Consciousness.
The use of neuroleptic agents is contraindicated in comatose patients and patients with severe central nervous system depression. Neuroleptic agents may potentiate the CNS and respiratory depression in these patients.
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Altered Consciousness.
The use of most miscellaneous antipsychotics is contraindicated in patients with severe central nervous system depression or comatose states from any cause (e.g., lesion, disease, drug or alcohol induced).
Angioedema
Major:
telmisartan
Telmisartan has a major potential interaction with Angioedema.
The use of these agents is contraindicated in patients with a history of angioedema related to previous angiotensin-converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB) therapy or in patients with hereditary angioedema. Patients with a history of angioedema unrelated to these agents may be at increased risk of angioedema while receiving angiotensin II receptor (AR) antagonists. Patients should be advised to immediately report any signs or symptoms suggestive of angioedema (swelling of face, extremities, eyes, lips, or tongue, or difficulty swallowing or breathing) and to stop taking the medication until otherwise directed by their physician. Emergency therapy and/or measures to prevent airway obstruction are required for angioedema involving the tongue, glottis, or larynx. Treatment with angiotensin II receptor (AR) antagonists should be discontinued permanently if angioedema develops in association with therapy.
Biliary Obstruction
Moderate:
telmisartan
Telmisartan has a moderate potential interaction with Biliary Obstruction.
Telmisartan is primarily eliminated by biliary excretion, and only a minute amount is excreted in the urine. Dosage adjustments are not necessary in patients with renal impairment unless they are also volume-depleted, in which case therapy should be initiated under medical supervision. Patients with hepatic impairment or biliary obstruction may require a dosage adjustment. The manufacturer recommends administering telmisartan therapy with caution in patients with liver disease or biliary obstruction.
Brain Tumor
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Brain Tumor.
Some antipsychotics such as loxapine and molindone have antiemetic effects and may mask signs of overdosage of toxic drugs, and may obscure conditions such as intestinal obstruction and brain tumor.
Breast Cancer
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Breast Cancer.
The chronic use of neuroleptic agents can cause persistent elevations in prolactin levels due to antagonism of dopamine D2 receptors. Based on in vitro data, approximately one-third of human breast cancers are thought to be prolactin-dependent. The clinical significance of this observation with respect to long-term neuroleptic therapy is unknown. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in rodent studies but not in human clinical or epidemiologic studies. Until further data are available, therapy with neuroleptic agents should be administered cautiously in patients with a previously detected breast cancer. Caution is also advised in patients with preexisting hyperprolactinemia. Hyperprolactinemia may suppress hypothalamic gonadotrophin releasing hormone (GnRH), resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds; however, the clinical significance of elevated serum prolactin levels is unknown for most patients. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male patients.
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Breast Cancer.
Antipsychotic drugs can elevate serum prolactin concentrations, and this elevation persists during chronic administration. This should be considered if therapy will be prescribed in patients with previously detected breast cancer as one-third of human breast cancers are prolactin-dependent in vitro. Associated disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported. Appropriate laboratory testing and follow-up is advised.
Cardiovascular Conditions and Disorders
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Loxapine should be administered cautiously to patients with cardiovascular disease as increased pulse rates and transient hypotension have been reported. In the presence of severe hypotension requiring vasopressor therapy, the preferred drugs may be norepinephrine and angiotensin, as usual doses of epinephrine may be ineffective as loxapine inhibits its vasopressor effect.
Central Nervous System Disorders
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Central Nervous System Disorders.
Antipsychotics can lower the seizure threshold and trigger seizures in a dose-dependent manner. Seizures have been reported in patients receiving antipsychotic therapy and may occur in epileptic patients even with maintenance of routine anticonvulsant treatment. Therapy with antipsychotics should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. High dosages should be avoided if possible.
Cerebrovascular Insufficiency
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Cerebrovascular Insufficiency.
Neuroleptic agents may cause hypotension (including orthostatic hypotension), reflex tachycardia, increased pulse rate, syncope and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include hypertension, edema, arrhythmias, thrombophlebitis, myocarditis, angina, myocardial infarction, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation, diffuse T-wave flattening, and ST segment depression. Therapy with neuroleptic agents should be administered cautiously in patients with severe cardiovascular disease, pheochromocytoma, a predisposition to hypotension, or conditions that could be exacerbated by hypotension such as a history of myocardial infarction, angina, or ischemic stroke. Close monitoring of cardiovascular status, including ECG changes, is recommended at all dosages. If parenteral therapy is given, patients should be in a supine position during administration and for at least 30 to 60 minutes afterwards. Patients who experience orthostatic hypotension should be cautioned not to rise too abruptly. Occasionally, when severe, hypotension may require treatment with vasoconstrictive agents such as norepinephrine or phenylephrine. Epinephrine should not be used, however, since neuroleptic agents can reverse its vasopressor effects and cause a further lowering of blood pressure.
Dehydration
Major:
telmisartan
Telmisartan has a major potential interaction with Dehydration.
Angiotensin II receptor (AR) antagonists can cause symptomatic hypotension in patients with an activated renin-angiotensin system, such as volume- and/or sodium-depleted patients. Therapy with AR antagonists should be administered cautiously in such patients and in those predisposed to hypovolemic or hyponatremic states (e.g., patients on diuretic therapy, especially if high doses were used or if recently instituted; those on dietary salt restriction; renal dialysis patients). Volume and/or sodium depletion should be corrected prior to initiating therapy with AR antagonists, and the patient should be hemodynamically stable. Ideally, patients at risk for excessive hypotension should initiate AR antagonist therapy under close medical supervision, preferably with a lower dose, and followed closely for the first 2 weeks of treatment and whenever the dosage of AR antagonist or diuretic is increased.
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Dehydration.
Neuroleptic agents may cause hypotension (including orthostatic hypotension) and associated reflex tachycardia, syncope or dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few months. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension. Therapy with neuroleptic agents should be administered cautiously in patients with conditions that would predispose them to hypotension, such as hypovolemia or dehydration (e.g., due to severe diarrhea or vomiting). In addition, neuroleptic agents can interfere with the body's ability to regulate core body temperature, occasionally producing hyperthermia during strenuous exercise, exposure to hot weather, and concomitant treatment with anticholinergic medications. Patients who are dehydrated may be particularly susceptible.
Dementia
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Dementia.
Elderly patients with dementia- related psychosis treated with antipsychotic drugs are at increased risk of death. Most of these drugs are not approved for the treatment of patients with dementia- related psychosis.
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Dementia.
Antipsychotic drugs are not approved for the treatment of patients with dementia-related psychosis. Older patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death; although the causes were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. A causal relationship with antipsychotic use has not been established. In controlled trials in older patients with dementia-related psychosis, patients randomized to risperidone, aripiprazole, and olanzapine had higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, compared to patients treated with placebo.
Diabetes Mellitus
Major:
telmisartan
Telmisartan has a major potential interaction with Diabetes Mellitus.
The coadministration of some angiotensin II receptor blocker agents with aliskiren is contraindicated in patients with diabetes.
Diarrhea
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Diarrhea.
Neuroleptic agents may cause hypotension (including orthostatic hypotension) and associated reflex tachycardia, syncope or dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few months. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension. Therapy with neuroleptic agents should be administered cautiously in patients with conditions that would predispose them to hypotension, such as hypovolemia or dehydration (e.g., due to severe diarrhea or vomiting). In addition, neuroleptic agents can interfere with the body's ability to regulate core body temperature, occasionally producing hyperthermia during strenuous exercise, exposure to hot weather, and concomitant treatment with anticholinergic medications. Patients who are dehydrated may be particularly susceptible.
Gastrointestinal Obstruction
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Gastrointestinal Obstruction.
Most neuroleptic agents have anticholinergic activity, to which elderly patients are particularly sensitive. Clozapine and low- potency agents such as chlorpromazine and thioridazine tend to exhibit the greatest degree of anticholinergic effects in the class, while haloperidol as well as the newer, atypical agents like quetiapine, risperidone and ziprasidone have generally been associated with very low frequencies of anticholinergic adverse effects. Therapy with neuroleptic agents should be administered cautiously in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders.
Glaucoma, Narrow Angle
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Glaucoma, Narrow Angle.
Because of the possible anticholinergic action, loxapine should be used cautiously in patients with glaucoma or with a tendency to urinary retention, particularly if used with any other drugs with anticholinergic effect (e.g., antiparkinson medication).
Head Injury
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Head Injury.
Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.
Heart Disease
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Heart Disease.
Neuroleptic agents may cause hypotension (including orthostatic hypotension), reflex tachycardia, increased pulse rate, syncope and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include hypertension, edema, arrhythmias, thrombophlebitis, myocarditis, angina, myocardial infarction, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation, diffuse T-wave flattening, and ST segment depression. Therapy with neuroleptic agents should be administered cautiously in patients with severe cardiovascular disease, pheochromocytoma, a predisposition to hypotension, or conditions that could be exacerbated by hypotension such as a history of myocardial infarction, angina, or ischemic stroke. Close monitoring of cardiovascular status, including ECG changes, is recommended at all dosages. If parenteral therapy is given, patients should be in a supine position during administration and for at least 30 to 60 minutes afterwards. Patients who experience orthostatic hypotension should be cautioned not to rise too abruptly. Occasionally, when severe, hypotension may require treatment with vasoconstrictive agents such as norepinephrine or phenylephrine. Epinephrine should not be used, however, since neuroleptic agents can reverse its vasopressor effects and cause a further lowering of blood pressure.
Heart Failure
Moderate:
telmisartan
Telmisartan has a moderate potential interaction with Heart Failure.
Angiotensin II receptor (AR) antagonists can cause renal impairment in patients whose renal function depends on the activity of the renin-angiotensin-aldosterone system. In addition, symptomatic hypotension can occur in susceptible individuals, which may compromise renal and myocardial perfusion. In patients with severe congestive heart failure (CHF), treatment with AR antagonists has been associated with oliguria and/or progressive azotemia and, rarely, renal failure, myocardial ischemia, and death. Therapy with AR antagonists should be initiated cautiously in patients with severe CHF, especially when accompanied by volume and/or sodium depletion. In patients who experience a decline in renal function, discontinuation of AR antagonist therapy is usually not required provided there is symptomatic improvement of the heart failure and renal deterioration is well-tolerated. Transient hypotension is also not a contraindication to further treatment with AR antagonists, since therapy can usually be reinstated without difficulty after blood pressure stabilizes.
Hemodialysis
Major:
telmisartan
Telmisartan has a major potential interaction with Hemodialysis.
Angiotensin II receptor (AR) antagonists can cause symptomatic hypotension in patients with an activated renin-angiotensin system, such as volume- and/or sodium-depleted patients. Therapy with AR antagonists should be administered cautiously in such patients and in those predisposed to hypovolemic or hyponatremic states (e.g., patients on diuretic therapy, especially if high doses were used or if recently instituted; those on dietary salt restriction; renal dialysis patients). Volume and/or sodium depletion should be corrected prior to initiating therapy with AR antagonists, and the patient should be hemodynamically stable. Ideally, patients at risk for excessive hypotension should initiate AR antagonist therapy under close medical supervision, preferably with a lower dose, and followed closely for the first 2 weeks of treatment and whenever the dosage of AR antagonist or diuretic is increased.
History - Cerebrovascular Disease
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with History - Cerebrovascular Disease.
Neuroleptic agents may cause hypotension (including orthostatic hypotension), reflex tachycardia, increased pulse rate, syncope and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include hypertension, edema, arrhythmias, thrombophlebitis, myocarditis, angina, myocardial infarction, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation, diffuse T-wave flattening, and ST segment depression. Therapy with neuroleptic agents should be administered cautiously in patients with severe cardiovascular disease, pheochromocytoma, a predisposition to hypotension, or conditions that could be exacerbated by hypotension such as a history of myocardial infarction, angina, or ischemic stroke. Close monitoring of cardiovascular status, including ECG changes, is recommended at all dosages. If parenteral therapy is given, patients should be in a supine position during administration and for at least 30 to 60 minutes afterwards. Patients who experience orthostatic hypotension should be cautioned not to rise too abruptly. Occasionally, when severe, hypotension may require treatment with vasoconstrictive agents such as norepinephrine or phenylephrine. Epinephrine should not be used, however, since neuroleptic agents can reverse its vasopressor effects and cause a further lowering of blood pressure.
History - Myocardial Infarction
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with History - Myocardial Infarction.
Neuroleptic agents may cause hypotension (including orthostatic hypotension), reflex tachycardia, increased pulse rate, syncope and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include hypertension, edema, arrhythmias, thrombophlebitis, myocarditis, angina, myocardial infarction, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation, diffuse T-wave flattening, and ST segment depression.

Epinephrine should not be used, however, since neuroleptic agents can reverse its vasopressor effects and cause a further lowering of blood pressure.
Hyperkalemia
Moderate:
telmisartan
Telmisartan has a moderate potential interaction with Hyperkalemia.
Drugs that inhibit the renin-angiotensin, such as angiotensin II receptor antagonist system can cause hyperkalemia. Concomitant use of these agents with drugs that increase potassium levels may increase the risk of hyperkalemia. Use caution when using these agents together and monitor serum potassium periodically.
Hyperprolactinemia
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Hyperprolactinemia.
Antipsychotic drugs can elevate serum prolactin concentrations, and this elevation persists during chronic administration. This should be considered if therapy will be prescribed in patients with previously detected breast cancer as one-third of human breast cancers are prolactin-dependent in vitro. Associated disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported. Appropriate laboratory testing and follow-up is advised.

Ideally, patients at risk for excessive hypotension should initiate AR antagonist therapy under close medical supervision, preferably with a lower dose, and followed closely for the first 2 weeks of treatment and whenever the dosage of AR antagonist or diuretic is increased.
Hypotension
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Hypotension.
Neuroleptic agents may cause hypotension (including orthostatic hypotension), reflex tachycardia, increased pulse rate, syncope and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension.

Intestinal Obstruction
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Intestinal Obstruction.
Some antipsychotics such as loxapine and molindone have antiemetic effects and may mask signs of overdosage of toxic drugs, and may obscure conditions such as intestinal obstruction and brain tumor.
Liver Disease
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Liver Disease.
Most neuroleptic agents are extensively metabolized by the liver. The plasma concentrations of these agents may be increased and the half-lives prolonged in patients with impaired hepatic function. Therapy with neuroleptic agents should be administered cautiously in patients with significant liver disease. Lower initial dosages and slower titration may be appropriate.
Moderate:
telmisartan
Telmisartan has a moderate potential interaction with Liver Disease.
Telmisartan is primarily eliminated by biliary excretion, and only a minute amount is excreted in the urine. Dosage adjustments are not necessary in patients with renal impairment unless they are also volume-depleted, in which case therapy should be initiated under medical supervision. Patients with hepatic impairment or biliary obstruction may require a dosage adjustment. The manufacturer recommends administering telmisartan therapy with caution in patients with liver disease or biliary obstruction.
Neuroleptic Malignant Syndrome
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Neuroleptic Malignant Syndrome.
Neuroleptic Malignant Syndrome (NMS), a potentially fatal symptom complex, has been reported in association with the use of antipsychotic drugs. The diagnostic evaluation is complicated and the management requires immediate discontinuation of the antipsychotic therapy and intensive symptomatic treatment and medical monitoring. If a patient that has recovered from NMS requires antipsychotic drug treatment again, the reintroduction of therapy should be carefully considered as NMS recurrences have been reported.
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Neuroleptic Malignant Syndrome.
The central dopaminergic blocking effects of neuroleptic agents may precipitate or aggravate a potentially fatal symptom complex known as neuroleptic malignant syndrome (NMS). NMS is observed most frequently when high-potency agents like haloperidol are administered intramuscularly, but may occur with any neuroleptic agent given for any length of time. Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status and autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). Additional signs may include elevated creatine phosphokinase, myoglobinuria, and acute renal failure. Neuroleptic agents should not be given to patients with active NMS and should be immediately discontinued if currently being administered in such patients. In patients with a history of NMS, introduction or reintroduction of neuroleptic agents should be carefully considered, since NMS may recur.
Neutropenia
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Neutropenia.
The use of antipsychotics has been associated with events of leukopenia, neutropenia and agranulocytosis. Possible risk factors include preexisting low white blood cell count, and history of drug induced leukopenia/neutropenia. Patients with these risk factors should have complete blood count monitored frequently during the first few months of therapy. Patients should also be monitored for any signs or symptoms of infection. Treatment should be discontinued in any patient who develops a sore throat, fever, stomatitis, or other signs of infection along with a low WBC count or severe neutropenia (ANC < 1000/mm3).
Parkinsonism
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Parkinsonism.
The use of neuroleptic agents is associated with pseudo-parkinsonian symptoms such as akinesia, bradykinesia, tremors, pill-rolling motion, cogwheel rigidity, and postural abnormalities including stooped posture and shuffling gait. The onset is usually 1 to 2 weeks following initiation of therapy or an increase in dosage. Older neuroleptic agents such as haloperidol are more likely to induce these effects, and their use may be contraindicated in patients with Parkinson's disease or parkinsonian symptoms.
Renal Dysfunction
Moderate:
telmisartan
Telmisartan has a moderate potential interaction with Renal Dysfunction.
Telmisartan is primarily eliminated by biliary excretion, and only a minute amount is excreted in the urine. Dosage adjustments are not necessary in patients with renal impairment unless they are also volume-depleted, in which case therapy should be initiated under medical supervision. Patients with hepatic impairment or biliary obstruction may require a dosage adjustment. The manufacturer recommends administering telmisartan therapy with caution in patients with liver disease or biliary obstruction.
Moderate:
telmisartan
Telmisartan has a moderate potential interaction with Renal Dysfunction.
Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system and by diuretics. Patients whose renal function may depend in part on the activity of the renin-angiotensin system (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion) may be at particular risk of developing acute renal failure with these agents. Monitor renal function periodically in these patients. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function with these agents.
Respiratory Arrest
Major:
Adasuve
The loxapine in Adasuve has a major potential interaction with Respiratory Arrest.
The use of neuroleptic agents is contraindicated in comatose patients and patients with severe central nervous system depression. Neuroleptic agents may potentiate the CNS and respiratory depression in these patients.
Seizures
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Seizures.
Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.
Tachyarrhythmia
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Tachyarrhythmia.
Loxapine should be administered cautiously to patients with cardiovascular disease as increased pulse rates and transient hypotension have been reported. In the presence of severe hypotension requiring vasopressor therapy, the preferred drugs may be norepinephrine and angiotensin, as usual doses of epinephrine may be ineffective as loxapine inhibits its vasopressor effect.
Tardive Dyskinesia
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Tardive Dyskinesia.
Tardive dyskinesia (TD) has occurred in patients treated with antipsychotic drugs; the syndrome consists of potentially irreversible, involuntary, dyskinetic movements. The risk appears highest in older patients (particularly older women) but it is not possible to predict which patients are likely to develop TD; whether antipsychotic drugs differ in their potential to cause TD is unknown. The risk of TD and the likelihood that it will become irreversible increase with the duration of therapy and the total cumulative dose. The syndrome can develop after relatively brief treatment periods, even at low dosages; it may also occur after discontinuation of therapy. TD may remit (partially or completely) upon discontinuation of antipsychotic therapy, although antipsychotic therapy itself may suppress (or partially suppress) signs/symptoms of TD, possibly masking the underlying process; the effect of symptomatic suppression on the long-term course of TD is unknown. In patients with preexisting drug-induced TD, initiating or increasing the dosage of antipsychotic therapy may temporarily mask the symptoms of TD but could eventually worsen the condition. In patients requiring chronic therapy, the lowest dose and shortest duration of therapy producing a satisfactory clinical response are recommended; the need for continued therapy should be reassessed periodically. If signs/symptoms of TD occur during antipsychotic therapy, discontinuation of the offending agent should be considered; however, some patients may require treatment despite the presence of TD.
Urinary Tract Obstruction
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Urinary Tract Obstruction.
Because of the possible anticholinergic action, loxapine should be used cautiously in patients with glaucoma or with a tendency to urinary retention, particularly if used with any other drugs with anticholinergic effect (e.g., antiparkinson medication).
Vomiting
Moderate:
Adasuve
The loxapine in Adasuve has a moderate potential interaction with Vomiting.
Neuroleptic agents may cause hypotension (including orthostatic hypotension) and associated reflex tachycardia, syncope or dizziness, particularly during initiation of therapy or rapid escalation of dosage. Tolerance to the hypotensive effects often develops after a few doses to a few months. Rarely, fatal cardiac arrest has occurred secondary to severe hypotension. Therapy with neuroleptic agents should be administered cautiously in patients with conditions that would predispose them to hypotension, such as hypovolemia or dehydration (e.g., due to severe diarrhea or vomiting). In addition, neuroleptic agents can interfere with the body's ability to regulate core body temperature, occasionally producing hyperthermia during strenuous exercise, exposure to hot weather, and concomitant treatment with anticholinergic medications. Patients who are dehydrated may be particularly susceptible.
