Black Box Warning
|
Suicidality and Antidepressant Drugs
See full prescribing information for complete Boxed Warning.
Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of trimipramine maleate or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Trimipramine maleate is not approved for use in pediatric patients.

Pharmacology
Mechanism of Action
Trimipramine maleate is an antidepressant with an anxiety-reducing sedative component to its action. The mode of action of trimipramine maleate on the central nervous system is not known. However, unlike amphetamine-type compounds it does not act primarily by stimulation of the central nervous system. It does not act by inhibition of the monoamine oxidase system. The single-dose pharmacokinetics of trimipramine was evaluated in a comparative study of 24 elderly subjects and 24 younger subjects; no clinically relevant differences were demonstrated based on age or gender.
Structure
Trimipramine maleate is 5-(3-dimethylamino-2-methylpropyl)-10, 11-dihydro-5H-dibenz (b,f) azepine acid maleate (racemic form).
Trimipramine maleate capsules contain trimipramine maleate equivalent to 25 mg, 50 mg or 100 mg of trimipramine as the base. Inactive Ingredients: Each capsule contains lactose monohydrate and magnesium stearate. The capsule shell contains the following ingredients: D&C Yellow 10 (25 mg and 50 mg), FD&C Blue #1 (25 mg, 50 mg and 100 mg), FD&C Red #40 (50 mg), gelatin, and titanium dioxide. The capsules are imprinted in black ink that contains: alcohol, D&C yellow No.10 aluminum lake, FD&C blue No. 2/indigo carmine aluminum lake, FD&C blue No. 1/brilliant blue FCF aluminum lake, FD&C red No. 40/allura red AC aluminum lake, propylene glycol, iron oxide black and shellac glaze. Trimipramine maleate is prepared as a racemic mixture which can be resolved into levorotatory and dextrorotatory isomers. The asymmetric center responsible for optical isomerism is marked in the formula by an asterisk. Trimipramine maleate is an almost odorless, white or slightly cream-colored, crystalline substance, melting at 140°-144°C. It is very slightly soluble in ether and water, is slightly soluble in ethyl alcohol and acetone, and freely soluble in chloroform and methanol at 20°C.
