Half-lifeThe IM half-life of interferon alfa-2a is 6 hours to 8 hours; the half-life for IV infusion is 3.7 hours to 8.5 hours (mean 5.1 hours).
DescriptionInterferon a (human leukocyte protein moiety reduced). A type I interferon consisting of 165 amino acid residues with lysine in position 23. This protein is produced by recombinant DNA technology and resembles interferon secreted by leukocytes. It is used extensively as an antiviral or antineoplastic agent. An oral form is being developed by Amarillo Biosciences.
Indication/DiseaseFor the treatment of chronic hepatitis C, hairy cell leukemia, AIDS-related Kaposi's sarcoma, and chronic myelogenous leukemia. Also for the treatment of oral warts arising from HIV infection.
PharmacodynamicsUpregulates the expression of MHC I proteins, allowing for increased presentation of peptides derived from viral antigens. This enhances the activation of CD8+ T cells that are the precursors for cytotoxic T lymphocytes (CTLs) and makes the macrophage a better target for CTL-mediated killing. Interferon alpha also induce the synthesis of several key antiviral mediators, including 2'-5' oligoadenylate synthetase (2'-5' A synthetase) and protein kinase R.
Mechanism of ActionInterferon alpha binds to type I interferon receptors (IFNAR1 and IFNAR2c) which, upon dimerization, activate two Jak (Janus kinase) tyrosine kinases (Jak1 and Tyk2). These transphosphorylate themselves and phosphorylate the receptors. The phosphorylated INFAR receptors then bind to Stat1 and Stat2 (signal transducers and activators of transcription)which dimerize and activate multiple (~100) immunomodulatory and antiviral proteins. Interferon alpha binds less stably to type I interferon receptors than interferon beta.
ToxicityInterferon alfa-2 may cause serious adverse effects such as anemia; autoimmune diseases, including vasculitis, arthritis, hemolytic anemia, and erythematosus syndrome; cardiotoxicity; hepatotoxicity; hyperthyroidism or hypothyroidism; transient ischemic attacks; leukopenia; neurotoxicity; peripheral neuropathy; and thrombocytopenia. Some lesser side effects that may not need medical attention include blurred vision, change in taste or metallic taste, cold sores or stomatitis, diarrhea, dizziness, dry mouth, dry skin or itching, flu-like syndrome, increased sweating, leg cramps, loss of appetite, nausea or vomiting, skin rash, unusual tiredness, weight loss, and partial loss of hair.

Prescribed ForIntramuscular; Subcutaneous
Chemical Name6000000 unit / mL
FormulationRoferon-A (interferon alfa-2a, recombinant) is contraindicated in patients with: Hypersensitivity to Roferon-A (interferon alfa-2a, recombinant) or any of its components Autoimmune hepatitis Hepatic decompensation (Child-Pugh class B and C) before or during treatment Roferon-A (interferon alfa-2a, recombinant) is contraindicated in neonates and infants because it contains benzyl alcohol. Benzyl alcohol is associated with an increased incidence of neurologic and other complications in neonates and infants, which are sometimes fatal.
Physical Appearance lu like symptoms such as fatigue (58% to 95%), fever (25% to 92%), myalgia (68% to 71%), headache (44% to 66%), chills (23% to 64%), arthralgia/bone pain (25% to 47%), asthenia (6%), sweating (5%), leg cramps (3%), and malaise (1%). Weight loss (25% to 33%), change in taste or smell (3% to 25%), pain (24%), back pain (16%), night sweats (8%), menstrual irregularity (4%), reversible hearing loss, and tinnitus have also been reported
