Gentamicin pharmacokinetics in rats with reduced renal parenchyma
Abstract:
Pharmacokinetics of intramuscular gentamicin was observed in healty rats, in rats with renal parenchyma reduced to 1/5 of normal and in rats after bilateral nephrectomy. The results obtained support the assumption that in rats gentamicin is excreted only through the kidneys. Reduction of the renal parenchyma to 1/5 of normal is associated with extention of biological half-life only to double the control value. The results support the hypothesis that in the given experimental conditions gentamicin excretion in residual nephrons increases.
