How many of the following drugs is/are example(s) of broad spectrum antibiotic? Ofloxacin, Penicillin G, Terpineol, Salvarsan

Answer: 1

Solution

Let's classify each compound:
  • Ofloxacin: A fluoroquinolone antibiotic that is effective against both Gram-positive and Gram-negative bacteria — broad spectrum antibiotic
  • Penicillin G: Primarily effective against Gram-positive bacteria — narrow spectrum antibiotic
  • Terpineol: An organic compound used as a fragrance and flavoring agent, not an antibiotic
  • Salvarsan: An arsenic-based drug used specifically against syphilis (Treponema pallidum) — narrow spectrum

Only 1 drug (Ofloxacin) is a broad spectrum antibiotic.
