  • Abstract

    Indomethacin (IM) is one of the most widely used non-steroidal anti-inflammatory active pharmaceutical agent. However, its limited aqueous solubility and poor flowability creates bioavailability and formulation related problems. Role of various water-soluble carriers was studied for dissolution enhancement of a poorly soluble model drug, Indomethacin, using solid dispersion approach. Solid dispersions of Indomethacin with lactose monohydrate and different polymers Polyethylene glycol- 6000(PEG), Hydroxy Propyl Methyl Cellulose (HPMC), Polyvinyl Pyrrolidine (Povidone-30), and Beta Cyclodextrin (BCD) were prepared by kneading method. In the present investigation by keeping the constant amount of lactose monohydrate the effect of different hydrophilic polymers on solubility and dissolution were studied. The prepared solid dispersions were evaluated for content, saturation solubility, and dissolution and flowability parameters. Powdered solid dispersion with lactose monohydrate and used hydrophilic polymers showed approximately 10-20 fold increases in solubility over the pure drug. The all prepared solid dispersions shows improvement in dissolution profile and flowability compared to the raw indomethacin. Thus, the bioavailability of this poorly water-soluble drug and their flowability was greatly enhanced by formulation as solid dispersions with different hydrophilic polymers.
