Itraconazole is a triazole analogue with a broad spectrum of antifungal activity, which covers yeasts and moulds. It is active against dermatophytes, candidal and pityrosporum yeasts, as well as a number of fungi which cause subcutaneous and systemic infection. It is well absorbed and has significantly fewer side-effects than systemic imidazoles. It is a useful agent in all forms of candidal infection, and is particularly effective in pityriasis versicolor. It is a much more potent fungistatic agent than griseofulvin in dermatophytosis and is thus more effective over shorter treatment periods.
