Ofloxacin in the treatment of uncomplicated gonorrhea and chlamydial genital infection

: The subjects were 149 patients (96 men, 53 women) with gonorrhea only (n = 66), chlamydial infection only (n = 48), or both gonorrhea and chlamydial infection (n = 35). All patients with gonorrhea were culture positive; all isolates cultured before treatment were sensitive to ofloxacin. Chlamydial infection was diagnosed by culture, inclusions being identified by indirect immunofluorescence. The patients with gonorrhea received a single dose of 400 mg of ofloxacin. Clinical and microbiologic cure was evident in 86 of 88 patients evaluated at seven days after treatment and in 71 of 72 patients at 14 days. Three patients developed postgonococcal urethritis; the cause was chlamydial in two. The patients with chlamydial infection received 200 mg of ofloxacin twice daily for seven days. Clinical and microbiologic cure was evident in all 78 patients evaluated one day after treatment and in 73 of 74 patients at 14 days. Side effects were reported by 11 patients. It is concluded that ofloxacin is a safe and effective treatment for uncomplicated gonorrhea in patients with and without concurrent chlamydial infections.
