Imipenem versus moxalactam in the treatment of serious infections.

Imipenem (formerly imipemide, N-formimidoyl thienamycin, or MK0787) was compared to moxalactam in a randomized therapeutic trial involving 39 evaluable patients with serious bacterial infections. Of those treated with imipenem, 89% were cured or improved versus 60% for moxalactam (P = 0.06). Although mucocutaneous fungal infections occurred in both groups (25 and 10%, respectively), Streptococcus faecalis superinfection was seen in two patients in the moxalactam group only. Adverse drug reactions occurred with both drugs, although bleeding occurred in three patients treated with moxalactam.
