Which drug is listed under Other Antibiotics in the material?

• A. Amoxicillin
• B. Ofloxacin
• C. Minocycline
• D. Rifampicin

Answer: (D)

This item tests grouping antibiotics by class and recognizing which drugs fall outside the common class categories. Rifampicin belongs to the rifamycin family, which has a distinct mechanism—inhibiting bacterial DNA-dependent RNA polymerase—and a characteristic PK profile of strong hepatic enzyme induction and autoinduction. Because of its unique mechanism and classification, it is placed in a broad “Other Antibiotics” category in many materials. The other drugs listed—amoxicillin (a beta-lactam penicillin), ofloxacin (a fluoroquinolone), and minocycline (a tetracycline)—fit into their respective well-known antibiotic classes and so appear in those sections rather than in “Other Antibiotics.”
