To the Editor: Norfloxacin (Noroxin, Merck Sharp & Dohme, West Point, Pennsylvania) was the first of the fluorinated quinolone group of antimicrobial agents to be released by the Food and Drug Administration. Noroxin is a fluorinated quinolone derivative structurally related to nalidixic acid (NegGram, Winthrop/Breon, New York, New York). Nalidixic acid was originally synthesized in 1962 and is the prototype of a class of drugs known as quinolones. When compared with nalidixic acid, norfloxacin has a quinolone ring in place of a 1,8-napthyridine molecule. The addition of a 1-piperazinyl group at the 7-position of the quinolone ring confers antipseudomonal activity
