PPT-Gastro retentive Drug Delivery Systems

Gastro retentive Drug Delivery Systems Gastro retentive systems can remain in the gastric region for several hours and hence significantly prolong the gastric residence time of drugs Prolonged gastric retention. Introduction . When a drug is taken by a patient, the resulting biological effects, for example lowering of blood pressure, are determined by the pharmacological properties of the drug. These biological effects are usually produced by an interaction of the drug with specific receptors at the drug’s site of action.. 1. /59. CONTENTS. 2. /59. INTRODUCTION. APPROACHES. EVALUATION.
