Abstract
Early postmarketing phase vigilance for pazufloxacin mesilate (PZFX) was conducted from September 2002 to March 2003 based on “Guidelines for Implementation of Early Postmarketing Phase Vigilance Surveillance for Prescription Drugs, etc.(December 27, 2000).”
We first organized information delivery to provide monthly updates on adverse drug reactions to physicians and pharmacists working at all hospitals where PZFX was used.
A total of 203 adverse drug reactions in 180 patients were reported. Serious adverse reactions (43), most of which were already reported for other new quinolones, such as ciprofloxacin and ofloxacin, were observed in 40 patients.
