Pegylated interferon alfa-2b is a drug used to treat melanoma, as an adjuvant therapy to surgery. Also used to treat hepatitis C (typically, in combination with ribavarin), it is no longer recommended due to poor efficacy and adverse side-effects. Subcutaneous injection is the preferred delivery method. Belonging to the alpha interferon family of medications, the molecule is PEGylated to prevent breakdown. Approval for medical use in the United States was granted in 2001. It is on the World Health Organization's List of Essential Medicines as a therapy for chronic hepatitis C. Medical uses Hepatitis Till around 2010, PEGylated interferon alfa-2b in combination with ribavirin, was part of the standard regimen used in management of hepatitis C. Ribivarin helped in increasing the Sustained Virologic Response (SVR) even more. Developed by Schering-Plough, the drug was approved by Food and Drug Administration (FDA) of the United States in 2001, and has been on the World Health Org ...
