NCI Drug Dictionary


gemcitabine hydrochloride  Patient Information
The hydrochloride salt of an analogue of the antimetabolite nucleoside deoxycytidine with antineoplastic activity. Gemcitabine is converted intracellularly to the active metabolites difluorodeoxycytidine di- and triphosphate (dFdCDP, dFdCTP). dFdCDP inhibits ribonucleotide reductase, thereby decreasing the deoxynucleotide pool available for DNA synthesis; dFdCTP is incorporated into DNA, resulting in DNA strand termination and apoptosis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
