Which suffix is commonly found in penicillin-type antibiotics?

• A. Nium
• B. Cillin
• C. Micin
• D. Sone

Answer: (B)

Penicillin-type antibiotics are usually identified by the suffix -cillin. This naming pattern signals the penicillin family, which shares a beta-lactam core that disrupts bacterial cell wall synthesis. Examples like penicillin itself and its derivatives—ampicillin, amoxicillin, oxacillin, nafcillin, and piperacillin—all carry this suffix, helping clinicians recognize their class and related spectrum of activity. Other suffixes point to different drug families (for instance, -mycin or -micin for certain antibiotics like macrolides and aminoglycosides, and -sone associated with corticosteroids), so -cillin is the clue that links to penicillin-type antibiotics.
