- Abstract
Objective: The study was to design a mucoadhesive pH-triggered in situ gel of itraconazole, to prolong the residence time on oral mucosa, and to reduce the frequency of application and amount of drug administrated. Materials and Methods: Six formulations containing itraconazole 1% were prepared using different concentrations (0.5 and 0.7% w/w) of carbopol 934 (CB) and in combination with different viscosity-enhancing agents such as hydroxypropyl methylcellulose (HPMC) K4M (1 and 1.5%), xyloglucan (0.5%), and hyaluronic acid (1%), to formulate a pH-triggered system that undergoes sol-to-gel transition on change in pH to the physiological pH. The formulations were evaluated for physical appearance, PH, gelation capacity, rheological properties, spreadability, mucoadhesive force, and in vitro release of drug. Results: Formula F4 (0.7% CB, 1.5% HPMC K4M) showed acceptable pH and appearance, acceptable gelling capacity, and shear thinning rheological property, good mucoadhesive force, and provided 80% release over a 6-h period. Conclusion: The developed itraconazole mucoadhesive oral in situ gel was non-irritant, retarded the release for 6 h, and it is good alternative to conventional oral gel.
