<section class="Section" data-sectioncode="34089-3"><a name="LINK_5183b945-513a-4488-a22d-c0ffe891c515"></a><a name="section-10"></a><h1>11 DESCRIPTION</h1>SUPPRELIN LA is a sterile, non-biodegradable, diffusion-controlled, hydrogel polymer reservoir containing histrelin acetate, a synthetic nonapeptide analog of the naturally occurring gonadotropin releasing hormone (GnRH) possessing a greater potency than the natural sequence hormone. SUPPRELIN LA is designed to deliver approximately 65 mcg histrelin acetate per day over 12 months.The SUPPRELIN LA implant looks like a small thin flexible tube and consists of a 50-mg histrelin acetate drug core inside a 3.5 cm by 3 mm, cylindrical, hydrogel polymer reservoir (Figure 1). The implant may appear partially to completely full with variation in color from off-white to light brown. The color may be uneven within the core.Figure 1. SUPPRELIN LA Implant Diagram (not to scale)<img alt="hydrogel figure" src="supprelin-la-16.jpg"/>The chemical name of histrelin acetate is: L-Pyroglutamyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-N-benzyl-D-histidyl-L-leucyl-L-arginyl-L-proline N-ethylamide, acetate salt. The molecular formula for histrelin acetate is C66H86N18O12 x 2 CH3COOH and its molecular weight is 1443.70 (or 1323.52 as free base). Histrelin is also chemically described as 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-Nt-benzyl-D-histidyl-L-leucyl-L-arginyl-N-ethyl-L-prolinamide diacetate. The chemical structure of the free base (histrelin) is represented below in Figure 2. Figure 2. Structure of Histrelin<div class="Figure"><img alt="Structure of Histrelin" src="supprelin-la-17.jpg"/></div>The drug core also contains the inactive ingredient stearic acid NF. The hydrogel polymer reservoir is a hydrophilic cartridge composed of 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, trimethylolpropane trimethacrylate, benzoin methyl ether, Perkadox-16, and Triton X-100. Each implant is packaged hydrated in a glass vial containing 2 mL of sterile 1.8% sodium chloride solution, so that it is primed for immediate release of the drug upon insertion.A single use, sterile, Insertion Tool is provided along with the implant that can be used for the placement of the SUPPRELIN LA implant into the subcutaneous tissue of the inner aspect of the upper arm. The Insertion Tool is enclosed in a sterile bag and is provided separately from the implant in the Implantation Kit [see Recommended Procedure for Implant Insertion and Removal (<a href="#LINK_58e35f5f-d1d7-4604-857f-a84f8c3d63cb">2.2</a>)].</section>
