Procarbazine is an alkylating agent used for the treatment canine lymphoma. Procarbazine is T cell-specific and crosses the blood-brain barrier[1].

It also has immunosuppressive effects.

Recommended dose is 25 - 50 mg/m2 per day on a 21 day cycle.

Procarbazine can sometimes cause neurotoxicity, but myelosuppression (thrombocytopenia, leukopenia) seems to be the major limiting factor.
