Navelbine (50mg/5ml) 1 Vial Injection

Vinorelbine 50mg injection primarily acts as a mitotic inhibitor, disrupting microtubule formation during cell division. It binds to tubulin, preventing its assembly into microtubules, which are essential for chromosome segregation and spindle formation. This interference leads to cell cycle arrest at the metaphase stage, inhibiting cell proliferation and inducing apoptosis in rapidly dividing cancer cells. By destabilizing the mitotic spindle, vinorelbine disrupts the normal process of cell division, ultimately resulting in the inhibition of tumor growth.
