Drug Mode of Action ::  

Temozolomide, a triazene, is an inactive prodrug. It is chemically hydrolysed to 3-methyl-(triazen-1-yl) imidazole-4-carboxamide (MTIC), the active metabolite of dacarbazine. The cytotoxicity of MTIC is believed to be due alkylation of DNA, mainly at the O6 and N7 positions of guanine.

Drug Interactions ::

Valproic acid, other myelosuppressive agents.
