Interferon alfa (INN) or HuIFN-alpha-Le, trade name Multiferon, is a pharmaceutical drug composed of natural interferon alpha (IFN-α), obtained from the leukocyte fraction of human blood following induction with Sendai virus. Interferon alfa contains several naturally occurring IFN-α subtypes and is purified by affinity chromatography. Although the pharmaceutical product is often simply called "interferon alpha" or "IFN-α" like its endogenous counterpart, the product's International nonproprietary name (INN) is interferon alfa (the spelling of 'alfa' with 'f' reflects INN naming conventions).
Interferon alfa is used in a variety of treatments, including certain forms of leukemia, malignant melanoma, non-Hodgkin's lymphoma,[3] hepatitis B, and hepatitis C.[4][5][6] It is typically administered as an injection under the skin.[1]
