DESCRIPTION

Antagon™ (ganirelix acetate) Injection is a synthetic decapeptide with high antagonistic activity against naturally occurring gonadotropin-releasing hormone (GnRH). Ganirelix acetate is derived from native GnRH with substitutions of amino acids at positions 1, 2, 3, 6, 8, and 10 to form the following molecular formula of the peptide: N-acetyl-3-(2-napthyl)-D-alanyl-4-chloro-D-phenylalanyl-3-(3-pyridyl)-D-alanyl-L-seryl-L-tyrosyl-N ⁹ ,N ¹⁰ -diethyl- D-homoarginyl-L-leucyl-N ⁹ ,N ¹⁰ -diethyl-L-homoarginyl-L-prolyl-D-alanylamide acetate. The molecular weight for ganirelix acetate is 1570.4 as an anhydrous free base.

Antagon™ is supplied as a colorless, sterile, ready-to-use, aqueous solution intended for SUBCUTANEOUS administration only. Each sterile, prefilled syringe contains 250 µg/0.5 mL of ganirelix acetate, 0.1 mg glacial acetic acid, 23.5 mg mannitol, and water for injection adjusted to pH 5.0 with acetic acid, NF and/or sodium hydroxide, NF.
