Which antibiotics are examples of aminopenicillins?

• A. Amoxicillin, Ampicillin
• B. Penicillin G
• C. Cefazolin
• D. Azithromycin

Answer: (A)

Aminopenicillins are a subgroup of penicillins that include an amino group, which broadens their activity to cover more Gram-negative bacteria while keeping strong activity against many Gram-positive organisms. The classic examples are amoxicillin and ampicillin. Amoxicillin is commonly given orally and is favored for outpatient use, while ampicillin is typically given by injection. These two are broader in spectrum than penicillin G, which is a natural penicillin. Cefazolin is a cephalosporin, not an aminopenicillin, and azithromycin is a macrolide, a different antibiotic class entirely.
