FORMULATION AND EVALUATION OF ION EXCHANGE RESIN MATRIX TABLETS OF PROPRANOLOL
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2012, Vol 3, Issue 4
Abstract
In the present study, an attempt was made to prepare and evaluate Indion 254 ion exchange resin based matrix tablets by using sodium alginate, carrageenan and tamarind seed polyose for controlled release of propranolol HCl. The tablets were prepared by wet granulation method. The weight and drug contents of all the tablets were found to be uniform with the low SD values. The hardness and friability were within specified range. The pure drug propranolol HCl has shown complete dissolution within 60 min, whereas, drug-resin complex has shown drug release for 2.5 hrs. With the increase in concentration of carrageenan, the drug release was decreased whereas with the increase in concentration of tamarind seed polyose drug release was increased. The DSC and XRD analysis indicated that the drug was uniformly dispersed in an amorphous state in the polymer matrix. The FTIR analysis ruled out the interaction between drug and polymers used in the preparation. Swelling of the tablets decreased with an increased amount of carrageenan and it further decreased when the tablets were treated with glutaraldehyde. Swelling of the tablets increased with an increased amount of tamarind seed polyose. The in vitro drug release study indicated that the tablets containing tamarind seed polyose were capable of releasing the drug for 24 hrs. Drug release mechanism followed anomalous transport. The stability studies indicated that the formulations were stable, with respect to drug content and physical changes.
