Background: Natural gums and mucilage which hydrates and swells on contact with aqueous media are used as additives in the formulation of hydrophilic drug delivery system. Aim: The purpose of this study was to develop a new monolithic matrix system for complete delivery of Pioglitazone hydrochloride (HCl), in a zero-order manner over an extended time period using processed Aloe vera gel mucilage (PAG) as a release modifier. Materials and Methods: The matrices were prepared by dry blending of selected ratios of polymer and ingredients using direct compression technique. Physicochemical properties of dried powdered mucilage of A. vera were studied. Various formulations of pioglitazone HCl and A. vera mucilage were prepared using different drug: Polymer ratios viz., 1:1, 1:2, 1:3, 1:4, 1:5 for PAG by direct compression technique. Results: The formulated matrix tablets were found to have better uniformity of weight and drug content with low statistical deviation. The swelling behavior and in vitro release rate characteristics were also studied. Conclusion: The study proved that the dried A. vera mucilage can be used as a matrix forming material for controlled release of Pioglitazone HCl matrix tablets.
