Moxalactam for treatment of pelvic infections after cesarean delivery.

Moxalactam was given to 136 women for treatment of uterine infections after cesarean delivery. After an intravenous loading dose of 2 g, 36 women received 3 g daily and 100 were given 6 g daily. The clinical success rates of these two regimens were 86% and 89%, respectively; however, in four of five women for whom treatment with the 3-g daily dose failed, extensive surgery was necessary for cure. A total of 395 pathogens was isolated from these women with polymicrobial infections, and almost 90% were susceptible to moxalactam at less than or equal to 32 micrograms/ml. Adverse effects of therapy were minimal. Thus, moxalactam given initially as a dosage of 6 g daily is effective for treatment of women with pelvic infections after cesarean delivery.
