Preparation and Evaluation of Sustained Release Hydrogel Alginate Beads of Meclizine Hydrochloride

Abstract

Oral controlled drug delivery systems represent the foremost widespread kind of sustained drug delivery systems for the plain blessings of oral route of drug administration. Suchsystemsrelease the drug with constant or variable unleash rates. The oral controlled releasesystems show a typical pattern of drug unleash within which the drug concentration is maintained inthe therapeutic window for a chronic amount of your time (sustained release), thereby guaranteeingsustained therapeutic action. They are used as single dosage form. Present work involvespreparation and analysis of sustained release beads of beads of Meclizine Hydrochloride using Sodium alginate as natural polymer as well as Hydroxyl Propyl Methyl Cellulose K15, Sodium CMC. The technique employed for preparation of beads of the drug is ionotropic gelation.
