title: Absorption behavior of sulpiride described using Weibull functions.
abstract: Deconvolution absorption profiles of oral sulpiride formulations were calculated from plasma concentration-time data obtained in an open, 3-period study with a crossover of the 2 oral formulations in 12 healthy volunteers following single intravenous (100 mg) and oral (2 x 50 mg capsules, 200 mg tablets) application of sulpiride. A model based on 2 Weibull-functions, and applied using NONMEM, described the complex absorption profiles more satisfactorily than a first order absorption model or a model based on a single Weibull-function.
