Longer-acting PEG-Epo contains a chemical bond between an amino group present in epoetin beta and methoxy polyethylene glycol (PEG) butanoic acid; the addition of PEG is responsible for an increase in serum half-life of epoetin beta, and in CKD patients on dialysis the terminal half-life of PEG-Epo after IV administration is 134h [6, 8].
