darbepoetin alfa

View Patient Information
A recombinant analog of the endogenous cytokine erythropoietin, an erythropoiesis-stimulating protein. Due to the addition of two carbohydrate chains, darbepoetin alfa exhibits a three-fold greater half-life than does erythropoietin. Similar to erythropoietin, darbopoietin alfa binds to and activates epoetin receptors, thereby inducing the differentiation and maturation of erythrocyte progenitors, stimulating endothelial cell proliferation, and stimulating B-cell proliferation and immunoglobulin production.
