PAGASYS 180MG INJ (PEGINTERFERON)

The mechanism of action of PEGINTERFERON 180mg Injection involves its ability to mimic the biological effects of naturally occurring interferon. Interferons are proteins produced by the body's immune system in response to viral infections. PEGINTERFERON is a modified form of interferon alpha-2a, where polyethylene glycol (PEG) is attached to the interferon molecule. This modification increases the drug's half-life and slows its clearance from the body, allowing for less frequent dosing. Upon administration, PEGINTERFERON binds to specific cell surface receptors, triggering a cascade of intracellular signaling events. It induces the expression of various genes involved in antiviral responses, including those encoding enzymes that degrade viral RNA and proteins that inhibit viral replication. Additionally, it modulates the immune system by enhancing the activity of natural killer cells, macrophages, and T lymphocytes, thereby improving the body's ability to recognize and eliminate infected cells. The overall effect is a potent antiviral and immunomodulatory response, making PEGINTERFERON effective in treating certain viral infections and specific types of cancer.
