About
Gemcitabine, the active ingredient in this injection, is a potent antineoplastic agent belonging to the class of nucleoside analogs. It functions as a prodrug that is intracellularly metabolized into active diphosphate and triphosphate nucleosides. These active metabolites interfere with DNA synthesis and repair mechanisms by inhibiting DNA polymerase and ribonucleotide reductase, respectively. This disruption leads to DNA strand termination and ultimately induces apoptosis in rapidly dividing cancer cells. Administered intravenously, Gemcitabine is a cornerstone in the treatment of various solid tumors, demonstrating significant efficacy in controlling disease progression and improving patient outcomes.
Its mechanism of action targets the cellular machinery essential for cancer cell proliferation, making it a valuable component in chemotherapy regimens. The drug's ability to incorporate into DNA and RNA, thereby disrupting their normal function, underscores its cytotoxic effects. Due to its systemic nature, it affects both cancerous and rapidly dividing healthy cells, leading to a characteristic spectrum of side effects that require careful management.
