Abstract

Purpose: The aim of the present study was to formulate solid dispersion (SD) of Mesalamine to enrich the aqueous solubility and dissolution rate. Mesalamine is used in the management of acute ulcerative colitis and for the prevention of relapse of active ulcerative colitis.
Materials and Methods: In the present study, Solid dispersion of Mesalamine was prepared by Fusion and Solvent evaporation method with different polymers. SD’s were characterized by % practical yield, drug content, Solubility, FT-IR, PXRD (Powder X- ray diffractometry), SEM (Scanning electron microscopy), in vitro dissolution studies and Stability studies.
Results: The percent drug release of prepared solid dispersion of Mesalamine by fusion and solid dispersion method (FM47, FM67, SE47 and SE67) in 1:7 ratio was found 81.36±0.41, 86.29±0.64, 82.45±0.57and 87.25±1.14 respectively. The aqueous solubility and percent drug release of solid dispersion of Mesalamine by both methods was significantly increased. The PXRD demonstrated that there was a significant decrease in crystallinity of pure drug present in the solid dispersions, which resulted in an increased aqueous solubility and dissolution rate of Mesalamine.
Conclusion: The significant increase in aqueous solubility and dissolution rate of Mesalamine was observed in solid dispersion as the crystallinity of the drug decreased, absence of aggregation and agglomeration, increased wetability and good dispersibility after addition of PEG 4000 and PEG 6000.
