[Relationship between clinical efficiency of cefoperazone and the value of area under the time concentration curve in infectious diseases].
Clinical efficiency and side effects of cefoperazone (CPZ) against 40 infectious diseases in the field of internal medicine were studied. In addition, relationship between clinical efficiency and the value of area under the time concentration curve (AUC) was evaluated. It was possible to evaluate clinical responses in 36 cases of 40 infections; Responses were excellent in 15, good in 16, fair in 3 and poor in 2. An overall efficacy rate was 86.1%. A high dose of CPZ (2 g X 2/day) produced a higher efficacy rate than a low dose of the drug (1 g X 2/day) [95.8% (23/24 cases) vs. 66.7% (8/12 cases)] but the difference was not statistically significant. It was possible to evaluate bacteriological efficacy in 32 cases. Bacteria were eradicated in 29 (90.6%) and decreased in 3. The value of AUC in the high dose group was significantly higher than that in the low dose group. Values of AUC in cases of excellent or good clinical responses tended to be higher than values in cases of fair or poor responses. Side effects were noted in 4 cases, but they were not serious and improvements were observed without withdrawal of the drug except 1 case.
