Darbepoetin alfa is a synthetic analog of erythropoietin used to stimulate erythropoiesis. It is approved for the treatment of anemia associated with chronic kidney disease (CKD) and chemotherapy-induced anemia in cancer patients. It is longer-acting than recombinant human erythropoietin due to additional sialic acid groups.
Pharmacokinetics
Pharmacokinetic parameters in adults with chronic kidney disease after intravenous and subcutaneous administration. Subjects included both male and female patients, 18 to 75 years old, with stable renal function.
