Abstract

The objective of this research is a bioadhesive two layers controlled release tablets. The drug

release and the physical properties of tablet formulations using two polymers (Carrageenan 934

and Eudragit RL PO) at three levels and at a combination of different ratios of the two polymers

were evaluated. Formulation containing 40% total polymer level and a ratio of 1 Carrageenan to

1 Eudragit RLPO was the best formulationa. This formulation was tested in different dissolution

medium and at different rotational speed. The drug release was 96.3% in phosphate buffer pH

7.4; 59.1% in 0.1 N HCl and 46.4% in distilled water.

This study demonstrates the significance of the combination of two polymers for obtaining

controlled release bioadhesive matrix and enhancing the characteristic of each polymer.
