What are two examples of second generation fluoroquinolones?

• A. Ciprofloxacin and Ofloxacin
• B. Levofloxacin and Moxifloxacin
• C. Norfloxacin and Ofloxacin
• D. Ciprofloxacin and Levofloxacin

Answer: (A)

Second generation fluoroquinolones are the ones developed after the first wave to give stronger activity against Gram-negative bacteria, including Pseudomonas, while still being orally bioavailable. Ciprofloxacin and ofloxacin are classic examples of this generation, due to their potent Gram-negative coverage and proven use in a range of infections where those organisms are a concern. As generations advanced, later drugs like levofloxacin and moxifloxacin expanded activity to include more Gram-positive organisms and anaerobes, which is why they’re categorized as later generations rather than second generation.
