TCAs (applies to Endep) anticholinergic effects

Major Potential Hazard, High plausibility. Applicable conditions: Glaucoma/Intraocular Hypertension, Urinary Retention, 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.

TCAs (applies to Endep) cardiovascular disease

Major Potential Hazard, High plausibility. Applicable conditions: Hyperthyroidism, Cerebrovascular Insufficiency, History - Cerebrovascular Disease, History - Myocardial Infarction, Hypotension, Dehydration, Arrhythmias

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.

TCAs (applies to Endep) pheochromocytoma

Major Potential Hazard, Moderate plausibility.

Tricyclic and tetracyclic antidepressants (TCAs) may potentiate the effects of circulating catecholamines. Enhanced sympathetic activity can provoke hypertensive crises in patients with pheochromocytoma or other tumors of the adrenal medulla, such as some neuroblastomas. Therapy with TCAs should be administered cautiously in patients with these tumors.

Tricyclic antidepressants (applies to Endep) cardiovascular disease

Major Potential Hazard, Moderate plausibility.

Tricyclic antidepressants should be used with extreme caution in patients with evidence of cardiovascular disease because of the possibility of fluctuations in the blood pressure, arrhythmias, conduction defects, tachycardia, myocardial infarction and stroke. This also applies to patients who have family history of sudden death, cardiac dysrhythmias, or conduction disturbances. In some cases a gradual dose titration is recommended.

Tricyclic antidepressants (applies to Endep) depression

Major Potential Hazard, Moderate plausibility.

Adult and pediatric patients with depression 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.

Tricyclic antidepressants (applies to Endep) seizure disorders

Major Potential Hazard, Moderate plausibility. Applicable conditions: Alcoholism, CNS Disorder

Tricyclic antidepressants (TCAs), can lower the seizure threshold and trigger seizures. These drugs should be used with extreme caution in patients with a history of seizures, or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. Daily dose restrictions might apply for specific antidepressants. Physicians are encouraged to get additional dosing recommendations on the manufacturer's prescribing information.

TCAs (applies to Endep) bone marrow suppression

Moderate Potential Hazard, Low plausibility. Applicable conditions: Bone Marrow Depression/Low Blood Counts

The use of tricyclic and tetracyclic antidepressants (TCAs) has rarely been associated with bone marrow suppression. Leukopenia, agranulocytosis, thrombocytopenia, anemia, eosinophilia, purpura, and pancytopenia have been reported with some TCAs. Patients with preexisting bone marrow suppression or blood dyscrasias receiving TCAs should be monitored closely during therapy for further decreases in blood counts.

TCAs (applies to Endep) diabetes

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: 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.

TCAs (applies to Endep) renal/liver disease

Moderate Potential Hazard, High plausibility. Applicable conditions: Renal Dysfunction

Tricyclic and tetracyclic antidepressants (TCAs) are known to undergo metabolism in the liver. Some of the metabolites, such as those of imipramine, clomipramine and desipramine, may be pharmacologically active. Many of the metabolites are also excreted by the kidney. There are very limited data concerning the use of TCAs in patients with renal and/or liver disease. Therapy with TCAs should be administered cautiously in patients with significantly impaired renal or hepatic function. Dosage adjustments may be necessary.

TCAs (applies to Endep) schizophrenia/bipolar disorder

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Mania

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.

TCAs (applies to Endep) tardive dyskinesia

Moderate Potential Hazard, Moderate plausibility.

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. As with other drugs that possess anticholinergic activity, TCAs may aggravate tardive dyskinesia or induce previously suppressed symptoms. Patients with tardive dyskinesia requiring therapy with TCAs should be monitored for exacerbation of the condition.

Tricyclic antidepressants (applies to Endep) bipolar disorder screening

Moderate Potential Hazard, Moderate plausibility.

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 tricyclic antidepressant. This screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that tricyclic antidepressants are not approved for use in treating bipolar depression.

Tricyclic antidepressants (applies to Endep) glaucoma

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Glaucoma (Narrow Angle)

Tricyclic 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. Doxepin hydrochloride capsules are contraindicated in patients with glaucoma.

Tricyclic antidepressants (applies to Endep) liver/renal disease

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Renal Dysfunction, Liver Disease

In general, tricyclic antidepressants should be used with caution in patients with liver or renal disease, as these drugs are metabolized and excreted through the liver and kidneys. Dose selection, especially in the elderly patients that might have liver or renal dysfunction, should usually be limited to the smallest effective total daily dose. Some tricyclic antidepressants such as clomipramine and nortriptyline have occasionally been associated with elevations in SGOT (AST) and SGPT (ALT), and other hepatic adverse events such as jaundice. Although serious liver injury has only been reported rarely, therapy with these drugs should be administered cautiously in patients with preexisting liver disease and periodic monitoring of liver enzyme levels is recommended.
