Pharmacokinetics of thiamylal in cats.
Pharmacokinetics of thiamylal were determined after 13.2 mg of thiamylal/kg of body weight was administered IV to 6 healthy cats. Blood samples were obtained for 12 hours. Disposition of thiamylal best conformed to 2 multicompartmental models, a 2-compartment (n = 1) and a 3-compartment (n = 5) open pharmacokinetic model. The pharmacokinetic values were calculated for the overall best-fitted model, a mixed 2- and 3-compartmental model. The first or rapid distribution half-life was 1.91 minutes and a second, or slower, distribution half-life was 26.51 minutes. The elimination half-life was 14.34 hours. The apparent volume of distribution was 3.61 +/- 1.8463 L/kg, whereas the apparent volume of the central compartment was 0.46 +/- 0.2034 L/kg, and the total clearance was 0.135 +/- 0.0616 L/kg/h.
