Peginterferon alfacon-2 is a synthetic, pegylated form of interferon alpha used as an antiviral and immunomodulatory agent, primarily developed for the treatment of chronic hepatitis C infection. Its clinical use has largely been replaced by direct acting antivirals, but it was previously approved as part of combination therapy for hepatitis C.
Pharmacokinetics
No published literature reporting specific pharmacokinetic parameters such as clearance, volume of distribution, or absorption rate constants for peginterferon alfacon-2 in humans could be identified. Approximate estimates have been suggested based on available information for similar pegylated interferons.
