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 white to off-white practically odourless crystalline powder. It is soluble in chloroform, in dehydrated alcohol and in alcohol, sparingly soluble in ether and practically insoluble in water. The octanol/water partition coefficient of naproxen at pH 6.48 is 1.5. The chemical name for esomeprazole is bis(5-methoxy-2-[(S)-[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole-1-yl) magnesium amorphous. Esomeprazole 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) 2 Mg with molecular weight of 713.1. The structural formula is: The esomepraozle magnesium USP is a white to pale cream colored powder. It is slightly soluble in methanol and soluble in N,N-Dimethyl formamide and practically insoluble in heptane and 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

The active ingredients of naproxen and esomeprazole magnesium delayed-release tablets are naproxen which is an NSAID and esomeprazole magnesium which is a Proton Pump Inhibitor (PPI). Naproxen and esomeprazole magnesium delayed-release tablets (naproxen and esomeprazole magnesium) is combination of a nonsteroidal anti-inflammatory drug and a PPI available as an oval, yellow, multi-layer, delayed-release tablet combining an enteric-coated naproxen core and an immediate-release esomeprazole magnesium layer surrounding the core. Each strength contains either 375 mg of naproxen and 20 mg of esomeprazole (equivalent to 22.3 mg esomeprazole magnesium trihydrate) or 500 mg of naproxen and 20 mg of esomeprazole (equivalent to 22.3 mg esomeprazole magnesium trihydrate) for oral administration. The inactive ingredients are colloidal silicon dioxide, croscarmellose sodium, hypromellose, iron oxide yellow, magnesium oxide, magnesium stearate, methacrylic acid and ethyl acrylate copolymer dispersion, talc, plasacryl, polyethylene glycol, polysorbate 80, povidone, titanium dioxide. 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
