Itraconazole inhibits Cytochrome P-450 dependent enzymes resulting in impairment of the biosynthesis of ergosterol, a major component of the cell membrane of yeast and fungal cells. Being integral to the proper functioning of the cell membrane, inhibition of the synthesis of ergosterol leads to a cascade of abnormalities in permeability, membrane bound enzyme activity, and co-ordination of chitin synthesis leading to inhibition of growth, abnormal cell wall formation and accumulation of intracellular lipids and membranous vesicles.
SUBA (Super Bio-available) technology is a novel technology for enhancing the bioavailability of poorly soluble drugs. This technology utilizes a solid dispersion of drug in a polymer that improves the dissolution of poorly soluble drugs compared to their normal crystalline form. SUBA technology Itraconazole is an orally active triazole antifungal drug that has demonstrated a broad spectrum of activity and favorable pharmacokinetic profile.
