TRELSTAR is a white to slightly yellow lyophilized cake. When reconstituted, TRELSTAR has a milky appearance. It contains a pamoate salt of triptorelin, a synthetic decapeptide agonist analog of gonadotropin releasing hormone (GnRH). The chemical name of triptorelin pamoate is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-tryptophyl-L-leucyl- L-arginyl-L-prolylglycine amide (pamoate salt). The empirical formula is C64H82N18O13 C23H16O6 and the molecular weight is 1699.9. The structural formula is:
