choriogonadotropin alfa - Generic Medications

Ovidrel ® PreFilled Syringe (choriogonadotropin alfa injection) is a sterile liquid preparation of choriogonadotropin alfa (recombinant human Chorionic Gonadotropin, r-hCG). Choriogonadotropin alfa is a water soluble glycoprotein consisting of two non-covalently linked subunits - designated α and β - consisting of 92 and 145 amino acid residues, respectively, with carbohydrate moieties linked to ASN-52 and ASN-78 (on alpha subunit) and ASN-13, ASN-30, SER-121, SER-127, SER-132 and SER-138 (on beta subunit). The primary structure of the α - chain of r-hCG is identical to that of the α - chain of hCG, FSH and LH. The glycoform pattern of the α - subunit of r-hCG is closely comparable to urinary derived hCG (u-hCG), the differences mainly being due to the branching and sialylation extent of the oligosaccharides. The β - chain has both O- and N-glycosylation sites and its structure and glycosylation pattern are also very similar to that of u-hCG. The production process involves expansion of genetically modified Chinese Hamster Ovary (CHO) cells from an extensively characterized cell bank into large scale cell culture processing. Choriogonadotropin alfa is secreted by the CHO cells directly into the cell culture medium that is then purified using a series of chromatographic steps. This process yields a product with a high level of purity and consistent product characteristics including glycoforms and biological activity. The biological activity of choriogonadotropin alfa is determined using the seminal vesicle weight gain test in male rats described in the "Chorionic Gonadotrophins" monograph of the European Pharmacopoeia. The in vivo biological activity of choriogonadotropin alfa has been calibrated against the third international reference preparation IS75/587 for chorionic gonadotropin. Ovidrel ® PreFilled Syringe is a sterile, liquid intended for subcutaneous (SC) injection. Each Ovidrel ® PreFilled Syringe is filled with 0.515 mL containing 257.5 µg of choriogonadotropin alfa, 28.1 mg mannitol, 505 µg 85% O-phosphoric acid, 103 µg L-methionine, 51.5 µg Poloxamer 188, Sodium Hydroxide (for pH adjustment), and Water for Injection to deliver 250 µg of choriogonadotropin alfa in 0.5 mL. The pH of the solution is 6.5 to 7.5. Therapeutic Class: Infertility

Chorionic gonadotropin, a gonadotropin, is a polypeptide hormone produced by the human placenta and obtained from the urine of pregnant persons. Chorionic gonadotropin is a purified preparation composed of an alpha and a beta subunit. The alpha subunit is essentially identical to the alpha subunits of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha subunit of human thyroid-stimulating hormone (TSH). The beta subunits of these hormones differ in amino acid sequence. PREGNYL ® (chorionic gonadotropin) for injection is a sterile, dried powder for intramuscular injection after reconstitution. Each multiple-dose vial is only for use in one patient and contains 10,000 USP units of chorionic gonadotropin with dibasic sodium phosphate (4.4 mg) and monobasic sodium phosphate (5 mg). If required, pH is adjusted with sodium hydroxide and/or phosphoric acid. Each package also contains a 10-mL vial of solvent containing: water for injection with 0.56% sodium chloride and 0.9% BENZYL ALCOHOL (preservative), WHICH IS NOT FOR USE IN NEWBORNS. If required, pH is adjusted with sodium hydroxide and/or hydrochloric acid.
