Design and Evaluation of Press Coated Formulation of Aceclofenac and Comparison with Marketed Preparations.

The primary objective of the studies is to investigate whether compression coating could be used to produce tablets providing maximum drug plasma concentration 6 to 8 hours after an evening dose taken at approximately 22:00. Fast Dispersible core tablets containing Aceclofenac were prepared using super disintegrants like Ac-Di-Sol, Crospovidone, and Sodium starch glycolate through wet granulation method and evaluated for various parameters. Prepared press-coated tablets were characterized for physical parameters, drug content, lag time, in vitro drug release characteristics. Aceclofenac formulation tablets of batch F4 containing combination Methocel K4M and Methocel K100M showed desired lag time along with drug release as compared to other formulations. The Comparative dissolution study of an optimized formulation containing Aceclofenac was carried with marketed preparations also showed good results.
