title: [Pharmacokinetic studies on micronomicin in dogs. Comparison of intramuscular and drip intravenous administration models].
abstract: The pharmacokinetics of micronomicin (MCR) were studied in dogs after intramuscular (i.m.) and drip intravenous (d.i.v., 0.5, 1 and 2 hours) administration (10 mg/kg). After i.m. administration, the plasma levels of MCR followed a one-compartment open model, and after d.i.v. administration it followed a two-compartment open model. The peak plasma levels of MCR after i.m., 0.5, 1 and 2 hours d.i.v. administration were 28.7 +/- 6.5, 36.7 +/- 3.6, 30.2 +/- 5.1 and 20.3 +/- 2.3 mcg/ml, respectively. The pharmacokinetic parameters (T1/2, AUC, Kel, Vd and Cl) of MCR except Cmax and Tmax were not differentiated by the route of administration. Urinary recovery of MCR after d.i.v. administration was equal to that of MCR after i.m. administration.
