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.

Naproxen oral suspension, USP is available as a light-orange colored, pineapple flavored suspension containing 125 mg/5 mL of naproxen for oral administration. Naproxen is a propionic acid derivative related to the arylacetic acid group of nonsteroidal anti-inflammatory drugs. The chemical name is (S)-6-methoxy-α-methyl-2-naphthaleneacetic acid. The molecular weight is 230.26. Its molecular formula is C 14 H 14 O 3 , and it has the following chemical structure. Naproxen is an odorless, white to off-white crystalline substance. It is practically insoluble in water, soluble in ethanol and methanol. The octanol/water partition coefficient of naproxen at pH 7.4 is 1.6 to 1.8.
