Which drug is brand name Biaxin?

• A. Clarithromycin
• B. Azithromycin
• C. Erythromycin
• D. Fidaxomicin

Answer: (A)

Biaxin is the brand name for clarithromycin, a macrolide antibiotic. Clarithromycin works by binding to the 50S ribosomal subunit of bacteria, blocking the translocation step of protein synthesis, which hinders bacterial growth. This mechanism is shared among macrolides, but each drug has its own brand and specific uses, dosing, and spectrum. Understanding this helps you recognize brand versus generic names: azithromycin is a different macrolide (brand names include Zithromax), erythromycin is an older macrolide with its own brand/generic forms, and fidaxomicin is a newer drug used mainly for Clostridioides difficile infections.
