Fundamental and clinical studies on imipenem/cilastatin sodium (MK-0787/MK-0791) were performed in pediatric patients with infections. Results obtained were summarized below. The mean plasma half-life of MK-0787 was 0.84 hour with a dosage of 10 mg/kg and 0.90 hour with a dosage of 20 mg/kg. Mean plasma half-lives of MK-0791 were 0.40 hour and 0.71 hour for dosages of 10 mg/kg and 20 mg/kg, respectively. Urinary recovery of both MK-0787 and MK-0791 was high. The antibacterial activity of MK-0787 against clinically isolated organisms was determined. The MK-0787 was bactericidal against a broad spectrum of both Gram-positive and Gram-negative pathogens. The MK-0787/MK-0791 was administered to 32 pediatric patients with various infections. The overall clinical efficacy rate was 96.9%. Side effects observed were loose stools in one patient, diarrhea in another and slight elevations of platelet and direct bilirubin, and eosinophilia were observed in 3 patients, respectively.
