Abstract
The surface deposition of papaverine on the previously emphasized papaverine-Veegum complex has been prepared. In this way, a simple therapeutic system as been obtained. In this system, the drug lays both in the interlayer, as in the complex, and on the carrier surface. Papaverine was released according to a zero order kinetics after the release of an initial rapid dose (priming dose).The in vitro results obtained with the Sartorius Simulator according to Stricker suggested both an absorption according to a zero order kinetics and the acievement in a short time of constant papaverine concentrations in the gastro-intestinal tract.
