PEGINTRON 50MCG INJ

Peginterferon alpha-2b is a modified form of interferon alpha-2b, where polyethylene glycol (PEG) is attached to the interferon molecule. This modification increases its half-life and slows down its clearance from the body. The mechanism of action involves binding to specific cell surface receptors, triggering a cascade of intracellular signaling events. It stimulates the production of various immune system components, including interferon-stimulated genes, which have antiviral, antiproliferative, and immunomodulatory effects. Specifically, it interferes with viral replication, enhances the activity of natural killer cells and T-lymphocytes, and inhibits the proliferation of cells, thereby suppressing viral infections and inhibiting tumor cell growth.
