Abstract
Gastro retentive delivery systems are designed to be retained in the stomach for a prolonged time and release their active ingredients and thereby enable sustained and prolonged input of the drug to the upper part of the gastrointestinal (GI) tract. The goal of any drug delivery system is to provide a therapeutic amount of drug to proper site in the body to achieve promptly and then maintain a desired drug concentration. Baclofen is a gamma-aminobutyric acid (GABA) agonist used as a skeletal muscle relaxant used for the relief of painful and uncomfortable muscle spasms caused by a variety of conditions. Twelve different formulation of Baclofen floating beads were successfully developed using emulsion solvent diffusion method. The beads had good yield and showed high, drug entrapment efficiency. The flow properties of beads were within the acceptable range and therefore would be easily filled into capsules. Study concludes successfully delivery of Baclofen by the means of floating beads.
