Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring gonadotropin-releasing hormone (GnRH). The analog possesses greater potency than the natural hormone. The chemical name is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-leucyl-L-leucyl-L-arginyl-N-ethyl-L-prolinamide acetate (salt) with the following structural formula: Where: n=1 or 2 Leuprolide acetate has a molecular weight of 1209.41 as "free base”. Leuprolide is freely soluble in water. LUTRATE DEPOT 22.5 mg for 3-month administration is available in a vial containing white to off white sterile lyophilized microspheres together with the corresponding sterile reconstitution diluent in a pre-filled syringe. When LUTRATE DEPOT and the diluent are mixed together they become a suspension intended as an intramuscular injection to be given ONCE EVERY 12 WEEKS as a single dose. Each vial of LUTRATE DEPOT 22.5 mg for 3-month administration delivers leuprolide acetate (22.5 mg), polylactic acid (188.4 mg), triethylcitrate (10.4 mg), polysorbate 80 (3.8 mg), mannitol (88.4 mg) and carmellose sodium (25 mg). The prefilled syringe containing the clear reconstitution diluent (2 mL) contains mannitol (16 mg), water for injection, and sodium hydroxide and hydrochloric acid to control pH. LUTRATE DEPOT is an extended release sterile, single dose injection in suspension form for intramuscular administration. Structure
