Gemcitabine
Pharmacology
Gemcitabine is an antineoplastic anti-metabolite. Anti-metabolites masquerade as purine or pyrimidine - which become the building blocks of DNA. They prevent these substances becoming incorporated in to DNA during the "S" phase (or DNA synthesis phase of the cell cycle), stopping normal development and division. Gemcitabine blocks an enzyme which converts the cytosine nucleotide into the deoxy derivative. In addition, DNA synthesis is further inhibited because Gemcitabine blocks the incorporation of the thymidine nucleotide into the DNA strand.

Patient Information
General �� Patients receiving therapy with Gemzar should be monitored closely by a physician
experienced in the use of cancer chemotherapeutic agents. Most adverse events are reversible and
do not need to result in discontinuation, although doses may need to be withheld or reduced.
There was a greater tendency in women, especially older women, not to proceed to the next
cycle.
Laboratory Tests �� Patients receiving Gemzar should be monitored prior to each dose with a
complete blood count (CBC), including differential and platelet count. Suspension or
modification of therapy should be considered when marrow suppression is detected.
