[Clinical trial of netilmicin in infections of respiratory organs and studies on its penetration into pleural fluid II. (author's transl)].
To 10 cases with respiratory infections, 200 mg, twice daily, of netilmicin was administered without other antibiotics and the following results were obtained. 1) Netilmicin was administered to 2 cases of pneumonia and 8 cases of bronchitis for 7 to 30 days, and 4 remarkably effective and 6 effective cases were observed, that is, netilmicin was effective in all cases. 2) Abnormal laboratory test values were found in 2 cases; 1 case showed slightly elevated creatinine value, and 1 case showed slightly increase GTP value, and these values were normalized rapidly without any treatment after discontinuation of netilmicin administration. Netilmicin 100 mg was intramuscularly injected to 15 patients with pleural effusion to see the time-course distribution of the drug to serum and to pleural fluid by determining the concentration of netilmicin. 1) Netilmicin concentrations in serum reached the peak at 30 minutes after the intramuscular injection and it gradually decreased, while in the pleural fluid, it reached the peak at 3 hours after the injection, and the peak value in the pleural fluid in average was 2.63 +/- 1.98 micrograms/ml, and it was still detectable at 24 hours after the injection. 2) The ratio of netilmicin concentrations in the serum and pleural fluid at the peak was 31.7 +/- 23.4%, and distribution of netilmicin into the pleural fluid was considered to be high enough.
