Diethylpropion is classified as which type of agent?

• A. Monoclonal antibody
• B. Anorexiants, Sympathomimetic Amine Anorectic
• C. GLP-1 receptor antagonist
• D. Serotonin receptor antagonist

Answer: (B)

This item tests pharmacologic classification of a weight‑loss agent. Diethylpropion is an anorexiant that falls into the category of sympathomimetic amines. It works by stimulating the central nervous system to increase norepinephrine signaling, which dampens appetite and reduces food intake. This mechanism—action on the adrenergic system to curb hunger—distinguishes it from biologic therapies like monoclonal antibodies, which are large proteins targeting specific molecules, and from GLP‑1 receptor antagonists, which block a gut-brain hormonal pathway. It also isn’t a serotonin receptor antagonist, which would block serotonin signaling rather than drive adrenergic effects. So the best classification is an anorexiant, specifically a sympathomimetic amine anorectic.
