IMPROVEMENT OF DISSOLUTION PROPERTIES OF ALBENDAZOLE FROM DIFFERENT METHODS OF SOLID DISPERSION
SOLID DISPERSION METHOD
Poor aqueous solubility of drugs results in poor absorption and bioavailability. The objective of Solid dispersion technology is to increase the dissolution properties of highly lipophilic drugs, by using different hydrophilic carriers thereby improving their bioavailability. This technology is useful for enhancing the dissolution, absorption and therapeutic efficacy of drugs in dosage forms. Albendazole is a broad-spectrum antihelminthic agent used for the treatment of a variety of parasitic worm infestations. It is practically insoluble in water but slightly soluble in solvents like chloroform, methanol, ethyl acetate, and acetonitrile. The aim of our study was to improve the dissolution profile of Albendazole using HPMC K 100 LV, Kollidon VA64 and Mannitol as carriers by solid dispersion techniques. From the prepared solid dispersion, formulation code CSF5 showed better result where carrier was HMPC K 100 LV at 1:10 ratio in solvent evaporation method. Among the carrier used here to conduct our study, HPMC K 100 LV showed better result for both kneading and solvent evaporation methods. And among the method employed here, solvent evaporation method showed better solubility of drug at 60 min also at 1:10 ratio which was 78.86%.
