Mechanism of Action

Gemcitabine is a synthetic pyrimidine nucleoside and cytarabine analogue which is metabolised intracellularly to active diphosphate and triphosphate nucleosides. It inhibits DNA synthesis by inhibiting DNA polymerase and ribonucleotide reductase. It also induces apoptosis and is primarily active against cells in the S-phase, but may also arrest cells at the G1-S border. Metabolism: Rapidly cleared from the blood and metabolised by cytidine deaminase in the liver, kidney, blood, and other tissues after IV admin. Excretion: Mainly excreted in the urine. Half life ranges from 42-94 minutes.

Special Precautions

Children, hepatic and renal impairment. May impair ability to drive or operate machinery. Discontinue on 1st sign of microangiopathic haemolytic anaemia. Prolonged infusion time (>60 minutes) and more frequent than wkly dosing may increase toxicity. Monitor CBC before every dose. Increased risk of haemolytic uraemic syndrome and/or thrombocytcpenic purpura which may lead to irreversible renal failure.
