Which suffix indicates a Barbiturate?

Which suffix indicates a Barbiturate?

• A. Barbiturate
• B. Beta-blocker
• C. Benzodiazepine
• D. Biotin

Answer: (A)

Drug names often reveal their class by their suffix. Barbiturates typically carry the -barbital (barbiturate) naming pattern, as seen in examples like phenobarbital and pentobarbital. That naming cue indicates the drug belongs to the barbiturate class. In your list, the label Barbiturate signals this class most clearly. The other options align with different drug families: beta-blockers usually end in -olol, benzodiazepines end in -pam or -zepam, and biotin is a vitamin with a completely different naming pattern.
