Biochem/physiol Actions

Itraconazole inhibits cytochrome P-450-dependent enzymes which results in the inhibition of ergosterol synthesis. It does so by interacting with 14-α demethylase, which is a cytochrome P-450 enzyme necessary to convert lanosterol to ergosterol. Ergosterol is a crucial compenent of fungal cell membranes. Therefore, it′s inhibition results in increased cellular permeability causing leakage of cellular contents. Itraconazole may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms, inhibit purine uptake, and impair triglyceride and phospholipid biosynthesis.

High speed electrospinning (HSES), compatible with pharmaceutical industry, was used to demonstrate the viability of the preparation of drug-loaded polymer nanofibers with radically higher productivity than the known single-needle electrospinning (SNES) setup. Poorly water-soluble itraconazole (ITRA) was formulated with PVPVA64...
