Aims: The aim this research work is to formulate and evaluate thermoreversible gel of antifungal agent Clotrimazole for treatment of vaginal infection.
Place and Duration of Study: Department of Biopharmaceutics, Government College of Pharmacy, Karad, Maharashtra, India, between June 2009 and July 2010.
Methodology: Different Formulations of thermoreversible gel of antifungal agent Clotrimazole were prepared by using various concentrations of ethanol, PEG 400, sodium dodecyl sulphate, polycarbophil and pluronic F 127 and pluronic F 68. The gel formulations were subjected for evaluation on the basis of rheological behaviour, mucoadhesive behaviour, in-vitro performance.
Results: The results indicate that Polymers such as polycarbophil, PEG- 400 in various concentrations to prepare formulations were found to release drug for period over 12 hrs. Without getting dislodged. The formulations have satisfactory rheological behavior and their diffusion profile is comparable to the marketed gel formulation. Significant difference was observed in the rheological behavior of formulations. Gel strength, spreadability, mucoadhesive strength of formulation B and C were desirable. Drug diffusion of formulation B and C were 95.2% release after 11 hrs 98.5% release after 11 hrs, respectively which was good as compared to marketed formulation showing drug diffusion of 102.2% after 10 hrs.
Conclusion: On basis of the results we concluded that developed thermoreversible gel of Clotrimazole will be better alternative to conventional dosage form Clotrimazole & will improve patient compliance.
