A novel itraconazole bioadhesive film for vaginal delivery: design, optimization, and physicodynamic characterization.

The purpose of this work was to design and optimize a novel vaginal drug delivery system for more effective treatment against vaginal candidiasis. Itraconazole was formulated in bioadhesive film formulations that could be retained in the vagina for prolonged intervals. The polymeric films were prepared by solvent evaporation and optimized for various physicodynamic and aesthetic properties.

Development and evaluation of sustained release gastroretentive minimatrices for effective treatment of H. pylori infection.

In the present work, sustained release gastroretentive minimatrices of amoxicillin have been designed and optimized using central composite design. Effect of amount of xanthan gum, rate controlling polymers (HPMC K100M CR/PEO coagulant (1:1)), carbopol 974P, and gas generating couple (sodium bicarbonate/citric acid (3:1)) was studied on dependent (response) variables, i.e.
