Liquisolid compact tablet of candesartan cilexetil with enhanced solubility using neusilin us2, aerosil 200 and transcutol hp

Abstract

Objective: An attempt was made to enhance solubility, dissolution and intestinal permeability of drug candesartan cilexetil by liquisolid technology. Methods: Liquisolid tablet was formulated using non-volatile solvent Transcutol HP, carrier material Neusilin US2 and coating material Aerosil 200. Appropriate quantities of excipients were calculated with the help of mathematical model to get liquisolid powder. A 32 full-factorial design was used further to optimize liquisolid powder. Results: DSC, XRD and SEM studies revealed absence of crystalline nature of drug in liquisolid powder. Liquisolid powder was further compressed into tablet and subjected to various evaluation tests such as in-vitro drug release and ex-vivo intestinal permeation study. Conclusion: Liquisolid technology was found to be promising due to enhance solubility, dissolution and permeation of candesartan cilexetil by 19.75, 3.09 and 2.4-fold, respectively.
