Itraconazole, an azole antifungal agent. Itraconazole is a 1:1:1:1 racemic mixture of four diastereomers (two enantiomeric pairs), each possessing three chiral centers. It may be represented by the following structural formula and nomenclature: (±)-1-sec-Butyl-4-[p-[4-[p-[[2R * ,4S * )-2-(2,4-dichloro phenyl)-2-(1H-1, 2, 4-triazol-1 ylmethyl)-1,3- dioxolan-4 yl]methoxy]phenyl]-1-piperazinyl]phenyl]- Δ 2 -1, 2, 4-triazolin-5- one or 4-[4-[4-[4-[[Cis-2-(2,4-dichlorophenyl)-2-(1H-1,2,4- triazol-1-ylmethyl)-1,3-dioxolan-4 yl]methoxy] phenyl]piperazin-1-yl] phenyl]-2-[(1RS)-1-methyl propyl]-2,4-dihydro-3H-1,2,4-triazol-3-one Itraconazole has a molecular formula of C 35 H 38 Cl 2 N 8 O 4 and a molecular weight of 705.63. It is a white or almost white powder. It is freely soluble in methylene chloride, sparingly soluble in tetrahydrofuran, very slightly soluble in alcohol, practically insoluble in water. It has a pKa of 3.70 (based on extrapolation of values obtained from methanolic solutions) and a log (n-octanol/ aq. Buffer of pH: 8.1) partition coefficient of 5.66 at pH 8.1. Itraconazole oral solution contains 10 mg of itraconazole USP per mL, solubilized by hydroxypropyl-β-cyclodextrin (400 mg/mL) as a molecular inclusion complex. Itraconazole oral solution is clear, colorless to yellowish brown liquid with a target pH of 2. Other ingredients are ascorbic acid, hydrochloric acid, propylene glycol, purified water, non crystallizing sorbitol solution, saccharin sodium, sodium hydroxide, ART Cherry flavor. structute
