The active ingredient in the proton pump inhibitor esomeprazole magnesium delayed-release capsules, USP for oral administration is bis (5-methoxy-2-[(S)-[(4-methoxy-3, 5-dimethyl-2-pyridinyl) methyl]sulfinyl]-1 H -benzimidazole-1-yl) magnesium trihydrate. Esomeprazole is the S- isomer of omeprazole, which is a mixture of the S- and R- isomers. (Initial U.S. approval of esomeprazole magnesium: 2001). Its molecular formula is C 34 H 36 MgN 6 O 6 S 2 • 3H 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. Esomeprazole magnesium is supplied as Esomeprazole magnesium delayed-release capsules, USP. Each delayed-release capsule contains 20 mg, or 40 mg of esomeprazole (present as 22.3 mg, or 44.5 mg esomeprazole magnesium trihydrate) in the form of enteric-coated pellets with the following inactive ingredients: Colloidal silicon dioxide, hypromellose, magnesium stearate, meglumine, methacrylic acid and ethyl acrylate copolymer dispersion, mono & diglycerides, poloxamer, sugar spheres, talc and triethyl citrate.
