Cơ Chế Tác Dụng :
PEGylation is a technology for the chemical attachment of polyethylene glycol (PEG) polymer chains to a broad range of drug substances such as peptides and proteins including antibody fragments; small molecules, and other drugs. Infergen is a bio-engineered type I interferon alpha that is FDA-approved for the treatment of patients with chronic hepatitis C infections.
The effect of PEGylation is to increase drug circulation time in the bloodstream, improve drug solubility and stability, and reduce immunogenicity. The potential advantages of PEGylation are to decrease dosing frequency, improve drug efficacy and safety, improve stability, and simplify drug formulation.
Chỉ Định :
Investigated for use/treatment in hepatitis (viral, C).
