Busulfan is a chemotherapy drug used for treatment of certain canine cancers. It has potent effects on bone marrow, resulting in suppression of bone marrow production of erythrocytes and leukocytes.

At doses of 10 - 30 mg/kg, busulfan produces a severe but in most cases reversible myelotoxicity[1].

This drug has been used for myeloblastic leukaemia, with limited responses[2].

It has also been used in combination with prednisolone to maintain remission in dogs with essential thrombocytopenia[3].

At high doses (10 mg/kg) it is myeloablative and is used prior to bone marrow transplantation in dogs with leucocyte adhesion deficiency[4].

Recommended dose rate is 3 - 4 mg/m2 or 0.1 mg/kg given orally every 24 hours.
