title: Pharmacokinetic studies of theophylline in cats.
abstract: The pharmacokinetics of theophylline were determined in adult cats and the data were fitted to a two-compartment model. Single intravenous and multiple oral doses of aminophylline were used. The mean plasma theophylline half-life (t1/2) following the single intravenous dose was 7.8 h and the mean apparent specific volume of distribution (V'd(area] was 0.46 1/kg. The absorption half-life (t1/2ab) was 0.5 h and the bioavailability was 96% following oral administration. There was excellent agreement between the predicted and observed plasma theophylline concentrations following multiple oral doses.
