DEVELOPMENT AND IN VITRO DISSOLUTION STUDY OF BINARY AND TERNARY SOLID DISPERSIONS OF ACECLOFENAC
Journal Title: UNKNOWN - Year 2019, Vol 4, Issue 1
Abstract
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. 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. 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. Keywords: Aceclofenac, in-vitro dissolution, PEG 4000, PEG 6000, poloxamer, solid dispersion.
