Which drug class is used to treat infections caused by bacteria that are responsive to antibiotics?

• A. Anti-impotence
• B. Anti-infective
• C. Antimigraine
• D. Antiprotozoal

Answer: (B)

Bacterial infections that respond to antibiotic therapy are treated with anti-infectives. This broad class covers drugs used to treat infections caused by various pathogens, including bacteria that are susceptible to antibiotics. Antibiotics are the subset that specifically target bacteria, but since the question points to infections that can be treated with such drugs, the overarching category here is anti-infectives. The other options address unrelated conditions—erectile dysfunction, migraines, or protozoal infections—so they don’t fit the scenario of treating bacterial infections with antibiotics.
