Drug interactions
Moderate drug interactions
Moderate:
bitolterol maprotiline
Applies to: bitolterol and maprotiline
Using bitolterol together with maprotiline can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a rare side effect.
You may be more susceptible if you have:
- a heart condition called congenital long QT syndrome
- other cardiac diseases
- conduction abnormalities
- electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting)
The risk may exist even when bitolterol or similar medications are given by oral inhalation directly into the lungs, and more so if these products are overused. Do not exceed the dose and frequency of use recommended on the product label or prescribed by your doctor.
Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications.
You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications.
It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Disease interactions
43 potential interactions Applies to: 31 conditions, including High Blood Pressure, Depression, Bipolar Disorder, Heart Attack, and Seizures.
Alcoholism
Major:
maprotiline
Maprotiline has a major potential interaction with Alcoholism.
The use of maprotiline is contraindicated in patients with seizure disorders. Maprotiline, a tetracyclic antidepressant, has a greater propensity to cause seizures than the tricyclic antidepressants. The majority of reported cases of maprotiline- related seizures occurred in patients without a history of seizures, although confounding factors were present in some, including the administration of concomitant medications known to lower seizure threshold, rapid dosage escalation, and exceeding the recommended dosage range. Therapy with maprotiline should be administered cautiously in patients with predisposing factors for seizures, such as head trauma, CNS abnormalities, and alcoholism.
Bipolar Disorder
Major:
maprotiline
Maprotiline has a major potential interaction with Bipolar Disorder.
A major depressive episode can be the initial presentation of bipolar disorder. Patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder prior to initiating treatment with a tetracyclic antidepressant. This screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that tetracyclic antidepressants are not approved for use in bipolar depression.
Moderate:
maprotiline
Maprotiline has a moderate potential interaction with Bipolar Disorder.
Tricyclic antidepressants (TCAs) may aggravate symptoms of psychosis in schizophrenic patients, particularly those with paranoid symptomatology. Depressed patients, usually those with bipolar disorder, may experience a switch from depression to mania or hypomania. These occurrences have also been reported rarely with the tetracyclic antidepressant, maprotiline. Therapy with these agents should be administered cautiously in patients with schizophrenia, bipolar disorder, or a history of mania.
Cardiovascular Conditions and Disorders
Major:
maprotiline
Maprotiline has a major potential interaction with Cardiovascular Conditions and Disorders.
Tricyclic and tetracyclic antidepressants (TCAs) may cause orthostatic hypotension, reflex tachycardia, syncope, and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Imipramine appears to have the greatest propensity to induce these effects, while secondary amines such as nortriptyline may do so less frequently. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, collapse and sudden death have occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include tachycardia, arrhythmias, heart block, hypertension, thrombosis, thrombophlebitis, myocardial infarction, strokes, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation. Therapy with TCAs should be avoided during the acute recovery phase following myocardial infarction, and should be administered only with extreme caution in patients with hyperthyroidism, a history of cardiovascular or cerebrovascular disease, or a predisposition to hypotension. Close monitoring of cardiovascular status, including ECG changes, is recommended at all dosages. Many of the newer antidepressants, including bupropion and the selective serotonin reuptake inhibitors (SSRIs), are considerably less or minimally cardiotoxic and may be appropriate alternatives.
Major:
maprotiline
Maprotiline has a major potential interaction with Cardiovascular Conditions and Disorders.
Maprotiline should be administered with extreme caution in patients with history of myocardial infarction, and history or presence of cardiovascular disease because of the possibility of conduction defects, arrhythmias, myocardial infarction, strokes and tachycardia.
Central Nervous System Disorders

Cerebrovascular Insufficiency
Major:
maprotiline
Maprotiline has a major potential interaction with Cerebrovascular Insufficiency.
Tricyclic and tetracyclic antidepressants (TCAs) may cause orthostatic hypotension, reflex tachycardia, syncope, and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Imipramine appears to have the greatest propensity to induce these effects, while secondary amines such as nortriptyline may do so less frequently. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, collapse and sudden death have occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include tachycardia, arrhythmias, heart block, hypertension, thrombosis, thrombophlebitis, myocardial infarction, strokes, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation. Therapy with TCAs should be avoided during the acute recovery phase following myocardial infarction, and should be administered only with extreme caution in patients with hyperthyroidism, a history of cardiovascular or cerebrovascular disease, or a predisposition to hypotension. Close monitoring of cardiovascular status, including ECG changes, is recommended at all dosages. Many of the newer antidepressants, including bupropion and the selective serotonin reuptake inhibitors (SSRIs), are considerably less or minimally cardiotoxic and may be appropriate alternatives.
Major:
maprotiline
Maprotiline has a major potential interaction with Cerebrovascular Insufficiency.
The use of tetracyclic antidepressants (TCAs) has occasionally been associated with significant orthostatic hypotension secondary to the alpha-1 adrenergic blocking effects of these drugs. Therapy with TCAs should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with TCAs. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.
Dehydration
Major:
maprotiline
Maprotiline has a major potential interaction with Dehydration.
Tricyclic and tetracyclic antidepressants (TCAs) may cause orthostatic hypotension, reflex tachycardia, syncope, and dizziness, particularly during initiation of therapy or rapid escalation of dosage.

A major depressive episode can be the initial presentation of bipolar disorder. Patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder prior to initiating treatment with a tetracyclic antidepressant. This screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that tetracyclic antidepressants are not approved for use in bipolar depression.
Major:
maprotiline
Maprotiline has a major potential interaction with Depression.
Adult and pediatric patients with depression and other psychiatric disorders may experience worsening of their symptoms and may have the emergence of suicidal thoughts and behavior. Patients should be monitored appropriately and observed closely for worsening of their symptoms, suicidality or changes in their behavior, especially during the first few months of treatment, and at times of dose changes. Families and caregivers should be advised of the need for close observation and communication with the treating physician. Discontinuing the medication should be considered if symptoms are persistently worse, or abrupt in onset. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Diabetes Mellitus
Moderate:
bitolterol
Bitolterol has a moderate potential interaction with Diabetes Mellitus.
Adrenergic bronchodilators may cause increases in blood glucose concentrations. These effects are usually transient and slight, but may be significant with dosages higher than those normally recommended. Large doses of IV albuterol (not commercially available in the U.S.) and terbutaline sulfate have been reported to cause exacerbation of preexisting diabetes mellitus and ketoacidosis. Therapy with adrenergic bronchodilators should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate. Systemic adverse effects are minimized, but not abolished, by administration of these agents via oral inhalation.
Moderate:
maprotiline
Maprotiline has a moderate potential interaction with Diabetes Mellitus.
Both elevation and lowering of blood sugar levels have been reported with the use of some tricyclic antidepressants (TCAs). Rarely, these effects have also occurred with maprotiline, a tetracyclic antidepressant. Patients with diabetes should be monitored for worsening control of blood glucose when treated with these agents, particularly during dosage escalation or whenever dosage has been altered.
Diarrhea
Major:
maprotiline
Maprotiline has a major potential interaction with Diarrhea.
The use of tetracyclic antidepressants (TCAs) has occasionally been associated with significant orthostatic hypotension secondary to the alpha-1 adrenergic blocking effects of these drugs.

Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with TCAs. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.
Gastrointestinal Obstruction
Major:
maprotiline
Maprotiline has a major potential interaction with Gastrointestinal Obstruction.
Tricyclic and tetracyclic antidepressants (TCAs) have anticholinergic activity, to which elderly patients are particularly sensitive. Tertiary amines such as amitriptyline and trimipramine tend to exhibit greater anticholinergic effects than other agents in the class. Therapy with TCAs 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. In patients with angle-closure glaucoma, even average doses can precipitate an attack. Glaucoma should be treated and under control prior to initiation of therapy with TCAs, and intraocular pressure monitored during therapy.
Glaucoma, Narrow Angle
Moderate:
maprotiline
Maprotiline has a moderate potential interaction with Glaucoma, Narrow Angle.
Tetracyclic antidepressants as other type of antidepressants have an effect on pupil size causing dilation. This effect can potentially narrow the eye angle resulting in increased intraocular pressure and angle closure glaucoma, especially in predisposed patients. These drugs should be used with caution in patients with anatomically narrow angle or history of glaucoma.
Glaucoma/Intraocular Hypertension
Major:
maprotiline
Maprotiline has a major potential interaction with Glaucoma/Intraocular Hypertension.
Tricyclic and tetracyclic antidepressants (TCAs) have anticholinergic activity, to which elderly patients are particularly sensitive. Tertiary amines such as amitriptyline and trimipramine tend to exhibit greater anticholinergic effects than other agents in the class. Therapy with TCAs 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. In patients with angle-closure glaucoma, even average doses can precipitate an attack. Glaucoma should be treated and under control prior to initiation of therapy with TCAs, and intraocular pressure monitored during therapy.
Heart Attack
Major:
maprotiline
Maprotiline has a major potential interaction with Heart Attack.
The manufacturer does not recommend the use of maprotiline during the acute phases of myocardial infarction.
Heart Disease
Moderate:
bitolterol
Bitolterol has a moderate potential interaction with Heart Disease.
Adrenergic bronchodilators can stimulate cardiovascular beta- 1 and beta- 2 receptors, resulting in adverse effects such as tachycardia, palpitation, peripheral vasodilation, blood pressure changes, and ECG changes (e.g., flattening of the T wave; prolongation of the QT interval; ST segment depression). Direct stimulation of cardiac tissues is mediated by beta- 1 receptors and thus less likely to occur with beta-2-selective agents such as albuterol. However, beta-2-selectivity is not absolute and can be lost with larger doses. High dosages of these agents have been associated with precipitation or aggravation of angina, myocardial ischemia, and cardiac arrhythmias. Therapy with adrenergic bronchodilators should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, and/or underlying cardiovascular disorders such as coronary insufficiency, cardiac arrhythmias, or hypertension. The recommended dosages should not be exceeded.
High Blood Pressure
Moderate:
