: a glycoprotein produced by recombinant DNA technology that is identical in amino acid sequence to human erythropoietin, stimulates the production of red blood cells, and is administered by injection especially to treat anemia (such as that associated with chronic kidney failure or chemotherapy) or to reduce the need of some noncardiac surgery-related blood transfusions ◆Epoetin is synthesized in several forms designated alfa, beta, delta, omega, and zeta using hamster ovary cells into which the gene coding for erythropoietin has been inserted. The epoetin designated alfa is marketed under the trademarks Epogen and Procrit and the epoetin designated beta is marketed under the trademark Mircera.
