Method for treating anemia using long-acting epo preparation

The present invention relates to a method for treating anemia using a long-acting EPO preparation and, more specifically, to a method for treating an anemia patient through verification of the safe and long-acting optimum effective dosage and usage when a fusion polypeptide containing EPO and immunoglobulin hybrid Fc is administered to the anemia patient. The administration of the fusion polypeptide leads to excellent long-lasting power compared with existing EPO products, and can be effectively used in the treatment of the anemia patient through the dosage and usage suitable to minimize side effects of the cardiovascular system, which may be caused by a rapid elevation reaction of hemoglobin as an anemia treatment effect.
