Baclofen immediate release mode of administration exhibit sharp plasma peaking that results in the emergence of side effects like hypotension. This research employs preformulation studies to design an optimum dosage form for baclofen to enhance therapeutic outcomes. These studies include partition coefficient and ex-vivo permeation studies. Partition coefficient was found to be 1.27 at pH 7.4. Permeation studies confirmed the presence of specialized transport mechanism through the GIT. It was concluded that an ideal formulation of baclofen should provide slow-release of the drug to avoid sharp peaking. Modified-release floating extrudates of baclofen were prepared using Carbopol 934 and HPMC with different gas-forming agents. Different release-retarding materials (Eudragit L100, Eudragit RS100 and Cetyl alcohol) were used as ingredients in the binder solutions. The prepared extrudates were assessed for their drug content, floating ability, friability properties and in vitro release properties. The prepared extrudates recorded buoyance characteristics for 24 h with a floating lag time varying from 0 to 73.34 sec. The optimized extrudates manifested extended baclofen release for up to 8 h compared to 0.2 h for marketed baclofen tablets. This approach was found efficient to provide greater bioavailability and minimize hypotension associated with commercial baclofen tablets.
