Which drug used by the anxious patient in the above case is classified as a GABA agonist?
Show answer and explanation
Correct answer: A. Clonazepam
- A. Correct. Clonazepam is a benzodiazepine that acts as a positive allosteric modulator of GABA-A receptors, enhancing the effect of GABA (the primary inhibitory neurotransmitter) — effectively a GABA agonist/enhancer.
- B. Aspirin inhibits COX enzymes to reduce prostaglandin synthesis; it has no GABA-related mechanism.
- C. Lisinopril is an ACE inhibitor that prevents conversion of angiotensin I to angiotensin II; no GABA mechanism.
- D. Atenolol is a selective beta-1 adrenergic blocker with no GABA mechanism.
