The imprinting ink contains ammonium hydroxide, iron oxide black, propylene glycol, shellac glaze. The chemical name for naproxen is (S)-6-methoxy-α-methyl-2-naphthaleneacetic acid. Naproxen has the following structure: Naproxen has a molecular weight of 230.26 and a molecular formula of C 14 H 14 O 3 . Naproxen, USP is an odorless, white to off-white crystalline substance. It is lipid soluble, practically insoluble in water at low pH and freely soluble in water at high pH. The octanol/water partition coefficient of naproxen at pH 7.4 is 1.6 to 1.8. The chemical name for esomeprazole, USP is bis(5-methoxy-2-[(S)-[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1 H -benzimidazole-1-yl) magnesium trihydrate. Esomeprazole, USP is the S-isomer of omeprazole, which is a mixture of the S- and R- isomers. Its molecular formula is (C 17 H 18 N 3 O 3 S)2Mg x 3 H 2 O with molecular weight of 767.2 as a trihydrate and 713.1 on an anhydrous basis. The structural formula is: The magnesium salt is a white to slightly colored crystalline powder. It contains 3 moles of water of solvation and is slightly soluble in water. The stability of esomeprazole magnesium is a function of pH; it rapidly degrades in acidic media, but it has acceptable stability under alkaline conditions. At pH 6.8 (buffer), the half-life of the magnesium salt is about 19 hours at 25°C and about 8 hours at 37°C. structure1 structure2
