[Clinical evaluations of tobramycin in treatment of chronic complicated urinary tract infections by intravenous drip infusion administration (author's transl)].
1. Clinical pharmacology The pharmacological studies on tobramycin (TOB) were studied in clinical patients. The peak serum levels following intravenous drip infusion (i.v.d.) administration of TOB 60 mg were 4.62 mcg/ml in 0.5 hour and 4.09 mcg/ml in 1 hour respectively which achieved at the discontinuance of the drug. In 1 case, the concentration in serum and urinary recovery were determined when 60 mg of TOB was given twice a day in i.v.d. at an interval of 5 hours. The peak serum level was 4.11 mcg/ml at the first administration, and 4.96 mcg/ml at the second. No significant accumulation of the drug was observed. The urinary recovery of TOB during 0 approximately 11.5 hours was 44%. 2. Clinical results Tobramycin was administered in a dose of 60 approximately 120 mg once or twice a day by i.v.d. against 18 cases of chronic complicated UTI. The duration of treatment varied but generally 5 days. An overall excellent or moderate effect was seen in 81%. 3. Clinical chemistry The clinical abnormal values from laboratory tests of renal, hepatic function and peripheral hematology in patients treated with TOB were observed in 2 cases. In 1 case BUN increase (17.6 leads to 23 mg/dl) and in the other GOT and GPT elevations (GOT 24.1 leads to 66.7 u, GPT 26.2 u leads to 68.8 u). The abnormal values, however, returned to normal within 2 weeks after the discontinuance of the drug. 4. Clinical tolerance Adverse reactions were encountered in 2 cases. The 1 case yielded skin rash with itching in the second day after therapy. The other case complained of general itching with mild headache 2 days after starting therapy. In the above cases TOB treatment was discontinued, soon after appearing these symptoms. The complete recovery was recognized within 2 days in each case. 5. Summary Based on the clinical pharmacology and clinical studies, intravenous drip infusion administration of tobramycin can be given safely and effectively in treatment of chronic complicated UTI.
