Abstract:
Introduction: Pantoprazole is a very suitable drug for the treatment of numerous
acid-related conditions in humans and mammals. Owing to its short half-life (0.9 - 1.9 h), it is
ideal for sustained release formulation.
Methods: This study was aimed at developing pantoprazole gastroretentive (GR) controlledrelease
tablets and to determine the effects of this formulation and processing parameters on
drug release and other critical quality attributes of directly compressed tablets produced using
different matrix-forming polymers, namely, Hydroxypropyl methylcellulose (HPMC), chitosan,
sodium alginate, maize starch, kappa- carrageenan, and propyl vinyl pyrrolidine PVP K-
30 when formulated into effervescent Floating Drug Delivery Systems (FDDS).
Results: The buoyancy lag time of less than 5 seconds and a total floating time of more than 12
hours for all batches is a good indication of achieved floatation for FDDS.
Conclusion: Validation processes initiated with the five batches indicated that the polymer
blends had the potential for the formulation of pantoprazole FDDS and, hence, could enhance
patient compliance and better treatment outcomes due to their sustained release potentials.
