Itraconazole is an azole-based antifungal drug containing three azoles, like fluconazole. It inhibits cytochrom P450-dependent enzymes and impairs the biosynthesis of ergosterol. It can be used to treate apergillosis, blasoplasmosis, cryptococcal meningitis, histoplasmosis and onychomycosis.
Mechanism of action
Like other azole-based antifungal agents, itraconazole interacts with 14--demethylase, a cytochrome P-450 enzyme necessary to convert lanosterol to ergosterol, an essential component of fungal cell membranes, by stopping sterol C-14 -demethylation. 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/or phospholipid biosynthesis[1].
Drug interactions
The azole-based antifungal agents have many drug interactions and some can be sever. This section is under construction, see ketoconazole for a partial list of drug interactions.
Chemical information
The IUPAC name for itraconazole is 2-butan-2-yl-4-[4-[4-[4-[[(2R,4S)-2-(2,4-dichlorophenyl)-2-(1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]piperazin-1-yl]phenyl]-1,2,4-triazol-3-one, and its chemical formula, C35H38Cl2N8O4, gives a molecular mass of 705.6334 g/mol.
