Darbepoetin alfa / d ɑːr b ə ˈ p oʊ ɪ t ɪ n / is a re-engineered form of erythropoietin containing 5 amino acid changes (N30, T32, V87, N88, T90) resulting in the creation of 2 new sites for N-linked carbohydrate addition. It has a 3-fold longer serum half-life compared to epoetin alpha and epoetin beta.
Erythropoietin (/ ɪ ˌ r ɪ θ r oʊ ˈ p ɔɪ. ɪ t ɪ n,-r ə-,-p ɔɪ ˈ ɛ t ɪ n,-ˈ iː t ɪ n /; [1] [2] [3] EPO), also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted mainly by the kidneys in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow.
Darbepoetin alfa, which early literature during its development often termed as novel erythropoiesis-stimulating protein (NESP), is a form created by five substitutions (Asn-30, Thr-32, Val-87, Asn-88 and Thr-90) that create two new N-glycosylation sites. [24]
Epoetin theta, sold under the brand name Biopoin among others, is a copy of the human hormone erythropoietin. [1] [2]The most common side effects include shunt thrombosis (clots that can form in blood vessels of patients on dialysis, a blood clearance technique), headache, hypertension (high blood pressure), hypertensive crisis (sudden, dangerously high blood pressure), skin reactions ...

Sales of Aranesp and Epogen were down 11% and 17%, respectively, yet newer products were able to overcome the anemia drug's never-ending slump, resulting in an overall 8% increase in product sales.
Epoetin alfa, sold under the brand name Epogen among others, is a human erythropoietin produced in cell culture using recombinant DNA technology. [ 8 ] [ 9 ] Epoetin alfa is an erythropoiesis-stimulating agent. [ 8 ]
Epoetin beta , sold under the brand name Neorecormon among others, is a synthetic, recombinant [4] form of erythropoietin, a protein that promotes the production of red blood cells. It is an erythropoiesis-stimulating agent (ESA) that is used to treat anemia , commonly associated with chronic kidney failure and cancer chemotherapy .
