From Dog

Fluconazole 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 itraconazole or ketoconazole.

Fluconazole 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 5 - 15 mg/kg every 12 - 24 hours orally for 4 weeks (dermatophytes) or 4 - 6 months (systemic mycoses).
