The pharmacological properties of Eprex

By the nature of Eprex epoetin alfa is a glycoprotein obtained by genetic engineering. It belongs to the pharmacological agents that stimulate the formation of red blood cells - red blood cells, and is different in properties from human erythropoietin.

The mechanism of action of the drug is that it stimulates the division and differentiation of erythrocyte precursor. This effect was selective, not affecting, for example, the formation of white blood cells - leukocytes. Studies have proven that Eprex has little ability to induce the formation of antibodies to it.

There is no evidence that Eprex has teratogenic or carcinogenic properties.

If surgery is planned with extensive blood loss in adults against the background of anemia mild or moderate severity, for the prevention of extensive blood transfusions in the future and restore the normal rate of formation of red blood cells, is used Eprex.

Contraindications

If after four weeks of treatment the patient hemoglobin rose to 10g / l or more, and analyzing reticulocytes in at least 40 000 in 1 mm, it confirms the correctness of the selected dose. If fewer targets these figures, the dose for the next 4 weeks must be increased to 300 IU / kg three times a week or 60 1 000 IU weekly.

If this dose after 4 weeks of treatment achieved sufficient increase in hemoglobin and reticulocytes, the dosage is deemed sufficient, and it stops. If the increase in hemoglobin and reticulocytes increased at less than the recommended dose of numbers, the treatment was stopped.

If the increase in hemoglobin is greater than 20 g / l for a month or achieve the desired level of 120 g / L, the dose of Eprex should be reduced by 25%. The excess hemoglobin blood 120 g / l treatment with epoetin alfa for a time suspended, and resumed after reduction of hemoglobin below 120 g / l at a dosage 25% less than the original. Introduction Eprex was continued for another one month after the end of chemotherapy.

When collecting blood before planned major surgery Eprex administered intravenously after blood collection. In this case it is administered two times per week, three weeks in a row, with each visit to the doctor is taken from a portion of the patient blood and maintain it for the same patient transfusion.
