Abstract The effect of domperidone (2 mg kg −1 ) on the pharmacokinetics of a single oral dose of theophylline (25 mg kg −1 ) was studied in the rat. Theophylline concentrations were measured serially for 12 h using an HPLC technique. Domperidone did not have any significant effect on any of the four parameters studied: peak plasma levels ( Cp max ), the time these were attained ( t max ), elimination half‐life ( t 1/2 ) and area under the plasma concentration‐time curve (AUC). Our data preliminarily suggests that domperidone may be safely coadministered with theophylline but clearly further studies in patients or relevant animal models of gastric motility disturbances are needed to reliably rule out any potential interaction between these agents.
