Mechanism of Action

Interferon alfa-2a has antiviral, antitumour and immunomodulatory activity. It inhibits replication of a wide range of RNA and DNA viruses. It also exerts antiproliferative effects on normal and malignant cells. Interferon alfa-2a suppresses antibody formation through an effect on B-lymphocytes and inhibits onset of delayed hypersensitivity. Absorption: >80% is absorbed (IM); peak plasma concentrations within 4-8 hr (IM). Metabolism: Excretion: Via urine (negligible amounts); 3.7-8.5 hr (elimination half-life).
