Optimisation of aceclofenac fast dissolving tablets employing starch xanthate using 23 factorial design

Abstract

The present study involves in the evaluation of starch xanthate as a superdintegrant in the formulation of fast dissolving tablets of poorly soluble drugs employing 23factorial design. By using gelatinization process starch xanthate was synthesized. Then the synthesized starch xanthate was evaluated under physical and micromeritic methods. To develop starch xanthate as a superdisintegrant, fast dissolving tablet of aceclofenac was prepared by direct compression method employing starch xanthate in different proportions in each case employing 23 factorial design. All the prepared fast dissolving tablets were evaluated for drug content, hardness, friability, disintegration time and other dissolution characteristics like PD10, DE5 and K1. The prepared starch xanthate was found to be fine, free flowing slightly crystalline powder. Starch xanthate shown good swelling in water. The swelling index was 50% and all micrometric properties shown good flow and compressibility needed for solid dosage from manufacturing. All the formulated fast dissolving tablets employing starch xanthate were of good quality with regard to drug content, hardness and friability and fulfilled the official (IP/USP) requirements of compressed tablets with regard to the above mentioned physical properties. Starch xanthate was found to be a superdisintegrant which enhanced the dissolution efficiency when combined with croscarmellose sodium, with the aceclofenac and hence it could be utilized in the formulation of fast dissolving tablets to provide immediate release of the contained drug within 10 minutes.
