RETACRIT™ Description (epoetin alfa-epbx)

11 DESCRIPTION

Epoetin alfa-epbx is an erythropoiesis-stimulating agent. Epoetin alfa-epbx is a 165-amino acid glycoprotein manufactured by recombinant DNA technology. It has a molecular weight of approximately 30,400 daltons and is produced in Chinese Hamster Ovary (CHO) cell line. The product contains the identical amino acid sequence of isolated natural erythropoietin.

RETACRIT (epoetin alfa-epbx) injection for intravenous or subcutaneous administration is a sterile, clear, colorless solution in vials in multiple formulations.

Each 1 mL single-dose vial of 2,000, 3,000, 4,000, and 10,000 Units of epoetin alfa-epbx contains calcium chloride dihydrate (0.01 mg), glycine (7.5 mg), isoleucine (1 mg), leucine (1 mg), L-glutamic acid (0.25 mg), phenylalanine (0.5 mg), polysorbate 20 (0.1 mg), sodium chloride (2.4 mg), sodium phosphate dibasic anhydrous (4.9 mg), sodium phosphate monobasic monohydrate (1.3 mg), and threonine (0.25 mg), in Water for Injection, USP. Sodium hydroxide and hydrochloric acid may be added to adjust the pH (pH 7.0 – 7.5).

Each 1 mL single-dose vial of 40,000 Units of epoetin alfa-epbx contains calcium chloride dihydrate (0.01 mg), glycine (7.5 mg), isoleucine (1 mg), leucine (1 mg), L-glutamic acid (0.25 mg), phenylalanine (0.5 mg), polysorbate 20 (0.1 mg), sodium chloride (2.2 mg), sodium phosphate dibasic anhydrous (5.7 mg), sodium phosphate monobasic monohydrate (1.5 mg), and threonine (0.25 mg), in Water for Injection, USP.
