Drug Mode 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.

Drug Interactions ::

Reduces clearance of theophylline. Enhanced myelosuppression with other myelosuppressive drugs (e.g. zidovudine). Drugs metabolised by CYP450 pathway (monitor for changes in pharmacologic or adverse effects of concomitant drug). Increased risk of toxicity of centrally acting drugs. Increased risk of renal failure with interleukin-2.
