Abstract
The effect of sustained-release on the pharmacokinetics of theophylline was examined by comparing two sustained-release formulations (Theo-Dur® and Theotard®) to an oral solution and i.v. preparation of the drug. Drug-level monitoring was performed by an HPLC assay. The absorption profiles of the three oral formulations were pharmacokinetically analyzed by using the Loo-Riegelman procedure. The absorption of theophylline after the administration of the Theo-Dur® and Theotard® was found to be of an apparent zero-order kinetics.
