From Dog

Itraconazole is a triazole antimycotic drug used in severe fungal infections in dogs[1] that are non-responsive to amphotericin B, terbinafine, or other azole drugs such as fluconazole or ketoconazole.

Itraconazole inhibits the fungal-mediated synthesis of ergosterol, resulting in fungal cell wall leakage of ions and resultant death.

This drug has also been used for treatment of systemic mycoses such as intestinal pythiosis[2].

Recommended dose rate is 10 mg/kg every 24 hours for 4 weeks (dermatophytes) or 4 - 6 months (systemic mycoses).
