IN VITRO DISSOLUTION ENHANCEMENT OF ALBENDAZOLE BY PREPARATION OF INCLUSION COMPLEXS WITH HP- ß CYCLODEXTRIN
Journal Title: Pharma Science Monitor-An International Journal Pharmaceutical Sciences - Year 2011, Vol 2, Issue 1
Abstract
With the introduction of combinatorial chemistry and high throughput screening, the properties of new chemical entities shifted towards higher molecular weight and increasing lipophilicity that results in decreasing aqueous solubility. It is not surprising that many drug candidates have poor water solubility since the initial selection of drug candidates are based on activity alone. Other physiochemical and biopharmaceutical properties such as permeability, biopharmaceutics and metabolism are rarely considered during the selection process. The aim of this study was to increase dissolution rate of albendazole poorly soluble drugs from BCS class II by complexation process. Complexation was prepared using cyclodextrine. Different techniques were employed for preparation of complexation with cyclodextrin like physical mixture, cogrinding, kneading technology, solvent coevaporation. The physical properties of the prepared solid mass of ABZ was characterized by in vitro dissolution studies, UV-V spectroscopy, Fourior transform infrared spectroscopy, differential scanning calorimetry (DSC) and Xray powder differaction spectroscopy. Additionaly, phase solubility studies were performed to support the in vitro dissolution study. The results of Fourior transform infrared spectroscopy shows the compatibility of drug with cyclodextrin, while differential scanning calorimetry (DSC) and X-ray powder differaction spectroscopy showed the confirmation of complexation of cyclodextrin with Abz.
