Impact of Gastric Emptying Kinetics on Dipyridamole Dissolution Using a Gastrointestinal Simulator
Gastric emptying plays a crucial role in the dissolution and absorption of oral drugs, particularly those with pH-dependent solubility, such as dipyridamole. This study evaluates the impact of gastric emptying kinetics on dipyridamole dissolution using a Gastrointestinal Simulator. A dynamic dissolu...

Gastric emptying plays a crucial role in the dissolution and absorption of oral drugs, particularly those with pH-dependent solubility, such as dipyridamole.

Results indicate that dissolution behavior is significantly influenced by the rate and pattern of gastric emptying, affecting drug solubility and potential bioavailability. The Weibull model provided a more flexible fit to experimental data, but the external control shows that significant differences exist between theorical and experimental gastric volumes.
