Abstract
Se estudian las características farmacocinéticas de propofol en 6 potrillos de 10 a 15 días de edad. Se determinaron parámetros farmacocinéticos de propofol, cuantificando sus concentraciones sanguíneas en función del tiempo por HPLC, tras su administración de 2,4 mg/kg por vía endovenosa al grupo de animales. Los datos de concentración se interpretaron por un modelo abierto de 2 compartimentos, obteniéndose, entre otros, los valores de t1/2a, t1/2b, Vdc, Vdss, Vdb, Cltotal y MRT. El análisis de los parámetros farmacocinéticos del propofol, indican que éste posee una rápida y pronta distribución a los tejidos y una rápida eliminación del organismo. Los parámetros farmacocinéticos obtenidos contribuyen a efectuar cálculos para una correcta dosificación
Pharmacokinetic variables of propofol were studied in 8 foals. Plasma levels of propofol at different time after a single intravenous dose of 2.4 mg/kg bw, were determined by HPLC. An open two compartments model was used to evaluate plasma levels of propofol and values of t1/2a, t1/2b, Vdc, Vdss, Vdb, Cltotal y MRT were obtained. Propofol pharmacokinetic disposition showed a rapid distribution and removal from organic tissues, and the reported pharmacokinetic variables contribute to determine the appropriate dose to be given
