Mezlocillin in the treatment of gonorrhea.

Mezlocillin (2 g) was administered by a single intravenous injection to 32 male patients with gonorrheal urethritis and to five female patients with gonorrheal cervicitis, none of whom had received any pre-treatment or had had any complications. The results of the treatment were "good" in 32 cases (86.5%), "fair" in three (8.1%) and "poor" in two patients (5.4%). One of the two "poor" cases showed no sensitivity to any penicillin derivative. Nausea during injection was observed twice, but the patients recovered immediately after the injection.
