Diazepam and midazolam provide which therapeutic effect?

• A. Analgesia
• B. Sedative
• C. Antagonism
• D. Antipyretic

Answer: (B)

Benzodiazepines such as diazepam and midazolam produce sedation by enhancing the effect of the neurotransmitter GABA at the GABA-A receptor. This makes neurons less excitable, leading to a calming, drowsy state often described as sedation, along with anxiolysis and sometimes amnesia. This is why they’re used to calm patients and help with procedures or before anesthesia. They do not provide analgesia (pain relief) or fever reduction, and “antagonism” isn’t a therapeutic effect of these drugs—reversal is possible with an antagonist like flumazenil, but that’s not a therapeutic action of the benzodiazepines themselves.
