Ropegra (180mcg/ml) 1 Vial Injection

Peginterferon alfa-2a is a modified form of interferon alfa-2a. It exerts its therapeutic effects by binding to specific cell surface receptors, leading to the activation of intracellular signaling pathways. This triggers a cascade of events, including the induction of antiviral proteins that interfere with viral replication, the enhancement of immune cell activity to combat viral infections, and the inhibition of cell proliferation, which can suppress tumor growth. The pegylation process increases the drug's half-life, allowing for less frequent dosing compared to unmodified interferon alfa.
