History
editPefloxacin was developed in 1979 and approved in France for human use in 1985.[1]
Licensed uses
edit- Uncomplicated gonococcal urethritis in males.[2]
- Bacterial infections in the gastrointestinal system.[2]
- Genitourinary tract infections.[2]
- Gonorrhoea, however, this use is no longer effective due to bacterial resistance.[3]
Pefloxacin has been increasingly used as a veterinary medicine to treat microbial infections.[4]
Mode of action
editPefloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It functions by inhibiting DNA gyrase, a type II topoisomerase, and topoisomerase IV,[5] which is an enzyme necessary to separate, replicated DNA, thereby inhibiting cell division.
Adverse effects
editTendinitis and rupture, usually of the Achilles tendon, are class-effects of the fluoroquinolones, most frequently reported with pefloxacin.[6] The estimated risk of tendon damage during pefloxacin therapy has been estimated by the French authorities in 2000 to be 1 case per 23,130 treatment days as compared to ciprofloxacin where it has been estimated to be 1 case per 779,600.[7]
