[Pharmacokinetics of astromicin intravenous drip infusion in patients with renal disorders].

Astromicin (ASTM), a new aminoglycoside antibiotic, was administered to 7 patients with renal disorders. Concentrations of ASTM in blood were determined for pharmacokinetic analysis. ASTM was administered by intravenous drip infusion over 1 hour at a dose of 200 mg to each of 6 patients and at a dose of 100 mg to 1 patient. Renal function was observed by the clearance of intrinsic creatinine (Ccr) as the indicator. Concentrations of ASTM in blood became higher and retention times longer as degrees of the loss of renal function were larger. Although ASTM is proved to be one of drugs with the highest degree of safety compared with other existing aminoglycoside antibiotics, it should be administered with care to patients with renal disorders.
