Mechanism of Action
Pegfilgrastim is a covalent conjugate of filgrastim and monomethoxypolyethyleneglycol (PEG). It is a colony-stimulating factor which binds to specific cell surface receptors of haematopoietic cells, thereby stimulating proliferation, differentiation, commitment, and end cell functional activation. Pegfilgrastim has delayed renal clearance and prolonged half-life relative to filgrastim as a result of conjugation with PEG.
