Inclusion complexes of pioglitazone HCl were prepared with ¦Â-cyclodextrin using various methods (physical mixing, kneading method, co-precipitation). The main aim of the present invention is to study the effect of the method of preparation on the dissolution profiles of pioglitazone HCl-¦Â-Cyclodextrin inclusion complexes . The phase solubility profile of pioglitazone HCl with ¦Â-cyclodextrin was classified as AL-type and stability constant with 1:1 molar ratio was 115.45, calculated from the phase solubility diagram. Formation of the inclusion complex between pioglitazone HCl and ¦Â-cyclodextrin was confirmed by the Fourier Transform Infrared (FT-IR) spectroscopy. The dissolution profile of inclusion complexes were determined and compared with those of pioglitazone HCl alone and its physical mixtures. The dissolution rate of the pioglitazone HCl-¦Â-cyclodextrin inclusion complex prepared by the co-precipitation method was six times higher when compared with the pure drug. The method of complexation of pioglitazone HCl in ¦Â-CD increased the dissolution rate of the drug in the following order: Coppt > KM > PM >Drug. %K Inclusion complex %K pioglitazone HCl %K ¦Â-cyclodextrin %U http://www.asiapharmaceutics.info/article.asp?issn=0973-8398;year=2010;volume=4;issue=2;spage=168;epage=172;aulast=Beloshe
