Formulation and Evaluation of Sublimed Mouth Dissolving Tablets of Aceclofenac

  Aceclofenac is a non-steroidal anti-inflammatory, analgesic and antipyretic drug used in the treatment of rheumatic arthritis, post-traumatic pain, masculo-skeletal and joint disorder. Problem with this drug is poor solubility in water hence poor bioavailability after oral administration. The objective of the research work was to develop and evaluate mouth dissolving tablets of Aceclofenac by using sublimation technique. The sublimation technique is used to increase the porosity of the tablets in which camphor was used as subliming agents which in turn forms the porous structure on the surface of tablets after sublimation. Aspartame was used as sweetening agent. The formulated tablets were evaluated for different parameters like weight variation, hardness, friability, drug content, disintegration time, wetting time, water absorption ratio, and In-vitro dissolution studies. Based on the results, formulation F-3 & F-6 containing Crosprovidon and Kyron T-314 10% concentration as superdisintegrants showed the least wetting time of about 17 & 13 sec, disintegration time of 25 & 18 sec and drug release of about 89.13 & 99.14% within 180 sec respectively and was found to be promising and selected as the optimized formulations. From the results, it was concluded that mouth dissolving tablets with improved Aceclofenac dissolution could be prepared by sublimation of tablets containing suitable subliming agent.
