Abstract
The main objective of the present study was to enhance the solubility and dissolution rate of poorly water soluble aceclofenac using its solid dispersion with β-cyclodextrin. FTIR and DSC study was carried out to find out any incompatibility. The phase solubility of drug was carried out in 1, 2, 5, and 10% of β-cyclodextrin in distilled water. Kneading method and solvent evaporation method was use to prepared solid dispersion of aceclofenac and β-cyclodextrin. Different evaluation tests like solubility study in different solvents, PXRD and in vitro dissolution study of aceclofenac- β-cyclodextrin inclusion complex were carried out. The overall finding indicated that β-cyclodextrin is a desirable water soluble carrier, that helps in increasing solubility of drug. Due to its structural feature, β-cyclodextrin forms a good inclusion complex that decreases contact angle of drug with water molecules by increasing wetting properties. Hence, it can be concluded that, β-cyclodextrin is better water soluble carrier molecule in terms of its compatibility and increasing solubility behavior of poorly water soluble drug aceclofenac.
