11:16 AM – 11:27 AM EDT
Introduction: Osmotically-controlled systems are intended to deliver the drug with stable and reproducible release kinetics, unaffected by the gastro-intestinal conditions (1, 2). This study investigated the performance of glipizide push-pull osmotic pump (PPOP) tablets manufactured using different formulation strategies, focusing on their resistance to physiological forces under simulated conditions. Pharmacokinetic (PK) simulations were used to assess the impact of the manufacturing process on the predicted drug plasma profiles and estimated equivalence amongst formulations.
Learning Objectives:
At the completion of this activity, participants will know
Identify critical factors affecting the performance of oral dosage forms
Evaluate push-pull osmotic tablets using non-standard, biorelevant dissolution testing
Predict new formulations in-vivo performance based on in-vitro testing and PK simulations
