DEVELOPMENT AND IN VITRO DISSOLUTION STUDY OF BINARY AND TERNARY SOLID DISPERSIONS OF ACECLOFENAC
Objective: The poor aqueous solubility of the drug exhibits in variable dissolution rate and hence poor bioavailability. Aceclofenac is poorly water soluble drug. The aim of the present study was to improve the water solubility and the dissolution rate of Aceclofenac by solid dispersion technique using different water soluble polymers. The term solid dispersions refer to the dispersions of one or more active ingredients in an inert carrier or matrix at solid state.
Methods: In this study, binary solid dispersion of Aceclofenac were prepared by fusion method using Polyethylene glycol 6000 (PEG 6000), Polyethylene glycol 4000 (PEG 4000), Poloxamer as carrier. Different drug-carrier weight ratio was used for this study. The effect of the carrier on the solubility and in-vitro dissolution were studied.
Results: It was found the drug was released 26.86% after 5 minutes and only 40.19% within 60 mins from active Aceclofenac on the other hand the release pattern of Aceclofenac from the binary solid dispersion formulations containing PEG 6000 in 1:5 ratio (Formulation coding: A5) showed the best result in comparison of other binary and ternary solid dispersion formulations which was 62.29% after 5 min and 83.03% within 60 mins. The hydrophilic polymers used for the preparation of solid dispersion are showed significant increase in the solubility of Aceclofenac.
Conclusion: This research showed that when Aceclofenac was dispersed in suitable water-soluble carriers such as PEG 6000, PEG 4000, Poloxamer, its dissolution were enhanced compared with pure drug.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
