title: Pharmacokinetics of methyprylon following a single oral dose.
abstract: Single oral doses of 300 mg of methyprylon were administered to 10 healthy volunteers. Plasma concentrations of methyprylon and its dehydro metabolite were measured using a recently developed HPLC assay. Plasma concentration-time data were fitted to a two-compartment model with either first-order absorption, zero-order absorption, or two consecutive, discontinuous, first-order absorption rate constants. Based on the criteria of visual inspection, the correlation coefficient, standard deviations of the parameter estimates, and the residual sum of squares, it was concluded that the zero-order absorption model fit the data best. Mean (+/- SD) values for the half-life (9.2 +/- 2.2 h), apparent clearance, (11.91 +/- 4.42 mL/h/kg) and apparent steady-state volume of distribution, (0.97 +/- 0.33 L/kg) were found.
