Which antidepressant class is denoted by the suffix '-pramine'?

• A. SSRI
• B. SNRI
• C. MAOI
• D. Tricyclic antidepressant (TCA)

Answer: (D)

The naming pattern helps identify the drug class here: the suffix -pramine is associated with tricyclic antidepressants. Drugs like imipramine, desipramine, amitriptyline, and clomipramine carry this ending, which has long been used to group them as TCAs. Mechanistically, TCAs block the reuptake of norepinephrine and serotonin, boosting their levels in the brain, and they often come with anticholinergic and sedative effects due to their receptor activities. Other antidepressant classes—SSRIs, SNRIs, and MAOIs—use different endings (for example, -xetine or -oxetine for many SSRIs/SNRIs, and -giline or distinct names for MAOIs), so the -pramine suffix clearly points to a tricyclic antidepressant.
