Among the patient's medications, which is a GABA agonist?
Show answer and explanation
Correct answer: B. Clonazepam
Benzodiazepines (diazepam, clonazepam, midazolam, lorazepam) are positive allosteric modulators of the GABA-A receptor — they increase the frequency of ClÔü╗ channel opening. Carbamazepine and phenytoin work through sodium-channel blockade.
