Introduction to the Pharmacology of CNS Drugs Questions
Question 1 of 5
The following drug is used in treatment of benzodiazepine toxicity:
Correct Answer: B
Rationale: Flumazenil (choice B) reverses benzodiazepine toxicity (e.g., overdose) by competitively antagonizing the GABAa receptor's benzodiazepine site, countering sedation or respiratory depression. Naloxone (choice A) targets opioid overdose, not benzodiazepines. Diazepam (choice C) and Chlordiazepoxide (choice D), both benzodiazepine agonists, worsen toxicity. Flumazenil's specificity is crucial in emergencies, distinguishing it from other antidotes.
Question 2 of 5
Drug treatment of anxiety states includes the following:
Correct Answer: D
Rationale: Diazepam (choice A), a benzodiazepine, reduces anxiety via GABA. Buspirone (choice B), a 5-HT1A agonist, offers non-sedating anxiolysis. Propranolol (choice C), a beta-blocker, manages physical symptoms (e.g., tachycardia). ‘All of the above' (choice D) reflects their combined utility in anxiety, covering acute and chronic needs.
