Procarbazine is a chemotherapy medication used for the treatment of Hodgkin's lymphoma and brain cancers. For Hodgkin's it is often used together with chlormethine, vincristine, and prednisone while for brain cancers such as glioblastoma multiforme it is used with lomustine and vincristine. It is typically taken by mouth. Common side effect include low blood cell counts and vomiting. Other side effects include tiredness and depression. It is not recommended in people with severe liver or kidney problems. Use in pregnancy is known to harm the baby. Procarbazine is in the alkylating agents family of medication. How it works is not clearly known. Procarbazine was approved for medical use in the United States in 1969. It is on the World Health Organization's List of Essential Medicines. In the United Kingdom a month of treatment cost the National Health Service 450 to 750 pounds. When used to treat Hodgkin's lymphoma, it is often delivered as part of the BEACOPP regimen that includes bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine (tradename Oncovin), prednisone, and procarbazine. The first combination chemotherapy developed for Hodgkin's lymphoma (HL), MOPP also included procarbazine (ABVD has supplanted MOPP as standard first line treatment for HL, with BEACOPP as an alternative for advanced/unfavorable HL). Alternatively, when used to treat certain brain tumors (malignant gliomas), it is often dosed as PCV when combined with lomustine (often called CCNU) and vincristine. Dose should be adjusted for kidney disease or liver disease. Very common (greater than 10% of people experience them) adverse effects include loss of appetite, nausea and vomiting. Other side effects of unknown frequency include reduction in leukocytes, reduction in platelets, reduction in neutrophils, which can lead to increased infections including lung infections; severe allergy-like reactions that can lead to angioedema and skin reactions; lethargy; liver complications including jaundice and abnormal liver function tests; reproductive effects including reduction in sperm count and ovarian failure.
