Dacarbazine

Overview
Dacarbazine (da-KAR-ba-zeen) (brand names DTIC, DTIC-Dome; also known as DIC or Imidazole Carboxamide) is an antineoplastic chemotherapy drug used in the treatment of various cancers, among them malignant melanoma and Hodgkin lymphoma. Antineoplastic drugs are drugs which interfere with cell growth and impede the formation of new tissue - in this case, tumor tissue. These drugs are also known as cytotoxic drugs. Dacarbazine belongs to the family of chemicals known as alkylating agents. Dacarbazine is normally administered by injection (a shot) or intravenous infusion (IV) under the immediate supervision of a doctor or nurse.

History
Dacarbazine gained FDA approval in May 1975 as DTIC-Dome. The drug was initially marketed by Bayer.

Side effects
Like many chemotherapy drugs, dacarbazine may have numerous serious side effects, because it interferes with normal cell growth as well as cancer cell growth. Among the most serious possible side effects are birth defects to children conceived or carried during treatment; sterility, possibly permanent; or immune suppression (reduced ability to fight infection or disease). Like most powerful drugs, it may produce more common side effects like nausea, fatigue, headache, etc.

Common uses
As of mid-2006, dacarbazine is commonly used as a single agent in the treatment of metastatic melanoma, and as part of the ABVD chemotherapy regimen to treat Hodgkin lymphoma.

Experimental
Dacarbazine + Oblimersen. In clinical trials for malignant melanoma.

Suppliers
