Isoconazole is commercially available as a cream (Travogen, Travocort + diflucortolone valerate). It has been approved in many countries since 1980. The ovules are out of commerce.
Structure and properties
Isoconazole (C18H14Cl4N2O, Mr = 416.1 g/mol) is present in drugs as a racemate and as isoconazole nitrate, a white powder that is very sparingly soluble in water. It is an imidazole and dichlorophenyl derivative. Isoconazole is structurally closely related to econazole (pevaryl).
