The erythropoietin analogs currently used to treat anemia in the United States are
epoetin alfa (sold under the names Procrit and Epogen) and
darbepoetin alfa (which is a more glycosylated form of epoetin, sold under the name Aranesp). There are similar biologic agents, such as
Mircera (a monoPEGylated erythropoietin-beta), sold by
Roche in Europe,
Chugai in Japan, and VFMCRP in the United States. ==References==
