possessing three chiral centers. The structure is similar

to that of the imidazole ketoconazole.

Absorption, Distribution, and Excretion. Itraconazole (SPORANOX,

others) is available as a capsule and a solution in hydroxypropylβ-cyclodextrin

for oral use. The capsule form of the drug is best

absorbed in the fed state, but the oral solution is better absorbed in

the fasting state, providing peak plasma concentrations >150% of

those obtained with the capsule. Itraconazole is metabolized in the

liver. It is both a substrate for and a potent inhibitor of CYP3A4.

Itraconazole is present in plasma with an approximately equal concentration

of a biologically active metabolite, hydroxy-itraconazole.

Bioassays may report up to 3.3 times as much itraconazole in plasma

as do physical methods such as high-performance liquid chromatography,

depending on the susceptibility of the bioassay organism to

hydroxy-itraconazole. The native drug and metabolite are >99%
