An interpretation of the drug release from monolithic water-swellable and soluble polymer tablets is presented. A convenient parameter, alpha, which compares the drug-diffusive conductance in the gel layer with the swelling and dissolving characteristics of the unpenetrated polymer was used
The testing of oxyethyltheophylline solutions for injection involved the separate study of their constituents, theophylline and ethophylline, particular attention being given to the behaviour of both these active agents under thermal stress in acid or alkaline medium. Acids exert little

Adenosine induced by hypoxia exerts various effects via different types of receptors. Recently, hypoxia was shown to be a strong inducer of vascular endothelial growth factor, a secreted endothelial cell specific mitogen. In this report, we studied on effects of

Two different types of derivatives of theophylline (Th-H) incorporating ethyleneoxy groups into the promoiety have been synthesized. One is a soft alkyl type where N-methyl-N-methoxyethyleneoxycarbonylaminomethyl chlorides have been used to alkylate Th-H in the 7 position. The other is in
