Tofranil belongs to which class of medications?

• A. SSRI
• B. MAOI
• C. Tricyclic antidepressant
• D. SNRI

Answer: (C)

Tofranil is a tricyclic antidepressant. This class works mainly by blocking the reuptake of norepinephrine and serotonin, increasing their levels in the synaptic gap to help improve mood. They also block several receptor types, including muscarinic (leading to dry mouth, constipation, urinary retention, blurred vision), histamine H1 (causing sedation), and alpha-adrenergic receptors (risk of orthostatic hypotension). These broad effects explain why TCAs have more side effects and safety concerns, especially in overdose, compared with newer antidepressants. In contrast, SSRIs selectively increase serotonin with fewer anticholinergic effects, SNRIs affect both serotonin and norepinephrine with a different side-effect profile, and MAOIs inhibit monoamine breakdown with dietary restrictions. Because of these distinctions, Tofranil is classified as a tricyclic antidepressant.
