Abstract

To determine the optimal clinical dose of meropenem (MEPM), a new carbapenem antibiotic for injection, in bacterial pneumonia, a dose-finding study was conducted by the blind method using imipenem/cilastatin (IPM/CS) as the control drug. Patients were given 0.5 g of MEPM a day (L-group) or 1.0 g of MEPM a day (H-group), or 1.0 g/1.0 g of IPM/CS a day (IM-group) for 14 days as a rule. Almost all patients had bacterial pneumonia, but some had pulmonary suppuration, or mycoplasmal pneumonia or primary atypical pneumonia. The results as evaluated by the committee were as follows; 1. In the case of bacterial pneumonia, the clinical efficacy rate was 95.7% (22/23) in the L-group, 79.3% (23/29) in the H-group and 84.0% (21/25) in the IM-group. There was a significant difference between the L-group and the H-group. In the total population, the clinical efficacy rate was 89.3% (25/28) in the L-group, 80.6% (25/31) in the H-group and 79.3% (23/29) in the IM-group. There were no significant differences among the 3 groups. 2. Bacteriologically, the eradication rate was 70% (7/10) in the L-group, 100% (13/13) in the H-group and 75% (6/8) in the IM-group. There were no significant differences among the 3 groups. 3. Side effects were observed in 1 of 35 patients in the H-group and 1 of 32 patients in the IM-group. None were severe, however. 4. The incidence of abnormal changes in laboratory findings was 32.1% (9/28) in the L-group, 32.4% (11/34) in the H-group and 46.4% (13/28) in the IM-group. There were no significant differences among the 3 groups. All the changes were mild in degree. 5. The usefulness rate was 89.3% (25/28) in the L-group, 77.4% (24/31) in the H-group and 73.3% (22/30) in the IM-group. There were no significant differences among the 3 groups. From the above results we concluded that a daily dose of 0.5 g was the optimal clinical dose for MEPM in bacterial pneumonia.
