A comparison of treatment outcomes for moxifloxacin versus ofloxacin/metronidazole for first-line treatment of uncomplicated non-gonococcal pelvic inflammatory disease

Abstract

Large randomized controlled trials support the efficacy of moxifloxacin for the treatment of uncomplicated pelvic inflammatory disease (PID). This study compares the clinical outcome and tolerability of treatment with moxifloxacin 400 mg once a day or ofloxacin 400 mg plus metronidazole 400 mg both twice daily in patients diagnosed with PID. A retrospective case-notes review was performed on patients diagnosed clinically with PID before and after local guidelines were changed to recommend moxifloxacin as first-line treatment for uncomplicated PID. Before the guidelines changed, 114/134 (85%) patients received the recommended first-line therapy versus 206/257 (80%) after the change, P = 0.3. There was no difference in the clinical outcomes between the two groups; significant improvement/resolved 77% versus 70%; marginal improvement 3% versus 11%; no change/worse 20% versus 18%, P = 0.14. Moxifloxacin is confirmed to be an effective alternative to ofloxacin/metronidazole for the treatment of PID in a large urban genitourinary clinic setting.
