To which class of antibiotics does amoxicillin belong?

• A. Cephalosporins
• B. Macrolides
• C. Penicillins
• D. Quinolones

Answer: (C)

Amoxicillin is classified as a penicillin antibiotic, which is a group known for its effectiveness against a variety of bacterial infections. Penicillins function by inhibiting cell wall synthesis in bacteria, ultimately leading to cell lysis and death. This mechanism is crucial for their antibacterial activity and distinguishes them from other antibiotic classes. In the context of bacterial resistance and spectrum of activity, penicillins, including amoxicillin, are often used to treat common infections such as respiratory tract infections, urinary tract infections, and certain skin infections. Amoxicillin is also noted for its broad-spectrum activity, making it effective against both Gram-positive and some Gram-negative bacteria. The other classes mentioned have different mechanisms and uses. Cephalosporins are structurally and functionally related to penicillins but possess different properties and spectra of activity. Macrolides also have a distinct mechanism, typically inhibiting protein synthesis, and are often used for atypical infections. Quinolones are a separate class that primarily act on bacterial DNA synthesis. Understanding these differences helps clarify how antibiotics are categorized and their clinical applications.
