Treatment of acute gynecologic infections with trovafloxacin. Trovafloxacin Surgical Group.

BACKGROUND

Trovafloxacin, a broad-spectrum fourth-generation quinolone with gram-positive and gram-negative aerobic and anaerobic bacterial activity, is available in oral and intravenous formulations. The objective of this prospective, multicenter, double-blind, randomized study was to compare the efficacy of trovafloxacin with that of cefoxitin, an approved drug for treatment of acute gynecologic infections, together with amoxicillin/clavulanic acid as oral follow-on treatment.

METHODS

Patients with a clinical diagnosis of acute pelvic infection received either intravenous alatrofloxacin with oral trovafloxacin follow-on (trovafloxacin) or a combined regimen of cefoxitin followed by amoxicillin/clavulanic acid for a maximum of 14 days. The primary endpoint was clinical response to therapy on follow-up at day 30.

RESULTS

Clinical success rates were comparable between the trovafloxacin (n = 107) and comparative (n = 119) groups at study end (90% vs. 86%, respectively; 95% confidence interval, -4.5, 12.5). Among clinically evaluable patients, clinical success rates for infections involving Enterococcus species were higher with trovafloxacin than with the comparative regimen at the end of treatment (96% and 85%) and at study end (96% and 86%).

CONCLUSION

Intravenous alatrofloxacin followed by oral trovafloxacin for a maximum of 14 days of total therapy was efficacious in the treatment of acute pelvic infections.
