Mygem 1gm Injection

About

Gemcitabine, the active component of Mygem 1gm Injection, is a potent nucleoside analog antimetabolite widely utilized in various chemotherapy regimens. Its mechanism of action involves intracellular metabolism to active diphosphate and triphosphate forms. Gemcitabine diphosphate acts as a potent inhibitor of ribonucleotide reductase, an enzyme critical for synthesizing deoxyribonucleotides, which are essential precursors for DNA replication and repair. Concurrently, gemcitabine triphosphate is incorporated directly into the DNA strand, leading to chain termination and effectively disrupting DNA synthesis and repair processes. This dual inhibitory effect on DNA synthesis and repair makes gemcitabine highly effective against rapidly dividing cancer cells, inducing apoptosis and inhibiting tumor growth. Administered intravenously, it is a cornerstone in the treatment of several solid tumors, often used alone or in combination with other antineoplastic agents to achieve optimal therapeutic outcomes and improve patient prognosis.
