Amphotericin B

From Dog

Amphotericin B is an antimycotic drug used in severe fungal infections in dogs[1] that are non-responsive to terbinafine, or azole drugs such as itraconazole, fluconazole or ketoconazole.

Amphotericin B binds with ergosterol, a component of fungal cell membranes, forming a transmembrane channel that leads to ion leakage and fungal cell death.

This drug has also been used for treatment of Leishmania infantum infections[2].

Recommended dose rate is 0.5 mg/kg three times weekly, given as an intravenous or subcutaneous injection.
