The solubility behaviour of drugs remains one of the most challenging aspects in formulation and development. The Complexation with cyclodextrins is very efficient technique for enhancement of solubility and used to improve the dissolution properties and bioavailability of poorly water soluble drugs. Today 40% of all new chemical entities suffer from poor aqueous solubility. It is generally recognized that low solubility or dissolution rate often become a rate limiting step in absorption of poorly water soluble drugs from gastro intestinal tract and compromise oral bioavailability. Aceclofenac was the drug candidate selected to improve its solubility and dissolution. An attempt was made to prepare complexation with β-CD and HP-β-CD. Complexes of β-CD and HP-β-CD in 1:1 molar ratios were prepared using three methods viz. kneading, solvent evaporation and microwave irradiation techniques. 1:1 (ACE: β-CD) complex tablet with kneading method showed more than 98% of drug release within 120 min in phosphate buffer pH 7.4 as dissolution medium. 1:1 (ACE:HP-β-CD) complex tablet with solvent evaporation method showed more than 95% of drug release within 120 min in phosphate buffer pH 7.4 as dissolution medium. 1:1 (ACE-β-CD) complex tablet with kneading method showed more than 81% of drug release within 120 min in 0.1N HCL pH 1.2 as dissolution medium. Release parameter t50% of developed and pure drug formulation indicated that the developed formulation has faster dissolution rate as compared to pure drug formulation
