Dacarbazine (DTIC), also known as imidazole carboxamide, is an antineoplastic agent, which is used in the treatment of metastatic malignant melanoma. In addition, this drug also is indicated for Hodgkin’s disease as a second-line therapy when used in combination with other effective agents. Dacarbazine works by methylating guanine at the O-6 and N-7 positions. Guanine is one of the four nucleotides that makes up DNA. The alkylated DNA strands stick together such that cell division becomes impossible. This affects cancer cells more than healthy cells because cancer cells divide faster. Dacarbazine is bioactivated in liver by demethylation to "MTIC" and then to diazomethane, which is an alkylating agent. Symptoms of anorexia, nausea, and vomiting are the most frequently noted of all toxic reactions. Over 90% of patients are affected with the initial few doses.

Sample Use Guides

Malignant Melanoma: the recommended dosage is 2 to 4.5 mg/kg/day for 10 days. Treatment may be repeated at 4 week intervals Hodgkin's Disease: The recommended dosage of Dacarbazine for Injection, USP in the treatment of Hodgkin’s disease is 150 mg/square meter body surface/day for 5 days, in combination with other effective drugs. Treatment may be repeated every 4 weeks.5 An alternative recommended dosage is 375 mg/square meter body surface on day 1, in combination with other effective drugs, to be repeated every 15 days
Route of Administration: Intravenous
The effect of alkyating agent dacarbazine (DTIC) and imexon, alone and in combination, was evaluated for growth inhibition (MTT), radiolabeled drug uptake, cellular thiol content (HPLC), and DNA strand breaks (Comet assay). Growth inhibition in vitro was additive with the two drugs. There was no effect on drug uptake or on the number of DNA strand breaks. There was a >75% reduction in cellular glutathione and cysteine with imexon but not DTIC. Co-administration of the two drugs in mice caused an increase in the area under the curve of both drugs, but the combination was not effective in reducing human A375 melanoma tumors in vivo.
