Formulation and Evaluation of Bilayer Floating Matrix Tablets For Captopril

The importance of the present investigation was to formulate a bilayer-floating tablet (BFT) for captopril using direct compression technology. The release layer contained captopril and various polymers such as HPMC-K15M, PVP-K30 and Carbopol 934p, alone or in combination with the drug. HPMC, K-grade and effervescent mixture of citric acid and sodium bicarbonate formed the floating layer. The f...

Formulation and in-vitro Evaluation of Captopril Floating Matrix Tablets Using HPMC 50cps

In the present investigation a gas powered tablets (floating tablets) of Captopril were prepared to increase the gastric retention time in order to improve the therapeutic effect of the drug by increasing its bioavailability. Captopril is antihypertensive drug, it is soluble in water; its maximum absorption is from the stomach and upper part of the intestine. The Gas powered tablets were prepar...

Formulation Optimization and In-vitro Evaluation of Oral Floating Captopril Matrix Tablets using Factorial Design

Purpose: To develop a zero-order sustained release floating formulation of captopril, and optimize its drug release for enhanced oral bioavailability. Methods: A relatively new approach, 3 full factorial design, was used to formulate floating captopril matrix tablets and to systematically optimize its drug release using varying levels of xanthan gum and hydroxypropyl methylcellulose (HPMC) K100...

Formulation and Evaluation of Sustained Release Matrix Tablets of Glipizide

      The purpose of this study was to develop a new monolithic matrix tablet to completely deliver glipizide in a zero order manner over a sustained period. Two approaches were examined using drug in a formulation that contain polymer like hydroxylpropyl methyl-cellulose K 100 (HPMCK) and Eudragit L 100. The granules were prepared by wet granulation method and thereby formulated as F-1, F-2. F...
