This is an injectable medication.
Pegylated interferon beta-1a is a “pegylated" form of interferon, meaning that polyethylene glycol is attached to the interferon molecules to allow them to maintain their biologic effects in the body for longer periods of time. Because the biologic effects in the body last longer, dosing can occur at less frequent intervals.
This medication is manufactured by a biotechnological process from one of the naturally-occurring interferons (a type of protein). It is made up of exactly the same amino acids (major components of proteins) as the interferon beta found in the human body.
Plegridy is approved by the FDA for the treatment of patients with relapsing forms of MS.
