YOSPRALA
(aspirin and omeprazole) Tablets

DRUG DESCRIPTION

The active ingredients of YOSPRALA are aspirin which is an antiplatelet agent and omeprazole which is a PPI.

YOSPRALA (aspirin and omeprazole) is an oval, blue-green, multi-layer film-coated, delayed release tablet consists of an enteric coated delayed-release aspirin core surrounded by an immediate-release omeprazole layer for oral administration. Each delayed-release tablet contains either 81 mg aspirin and 40 mg omeprazole printed with 81/40, or 325 mg aspirin and 40 mg omeprazole printed with 325/40.

The excipients used in the formulation of YOSPRALA are all inactive and United States Pharmacopeia/National Formulary (USP/NF) defined. The inactive ingredients in YOSPRALA include: microcrystalline cellulose, corn starch, pre-gelatinized starch, colloidal silicon dioxide, stearic acid, methacrylic acid copolymer dispersion, triethyl citrate, glyceryl monostearate, polysorbate 80, titanium dioxide, hydroxypropyl methycellulose, polyethylene glycol, polydextrose, triacetin, yellow iron oxide, FD&C Blue #2, talc, sodium phosphate dibasic anhydrous, carnauba wax and povidone.

Aspirin is acetylsalicylic acid and is chemically known as benzoic acid, 2-(acetyloxy). Aspirin is an odorless white needle-like crystalline or powdery substance. When exposed to moisture, aspirin hydrolyzes into salicylic and acetic acids and gives off a vinegary odor. It is highly lipid soluble and slightly soluble in water. Aspirin irreversibly inhibits platelet COX-1.

Omeprazole is a white to off-white crystalline powder which melts with decomposition at about 155 °C. It is a weak base, freely soluble in ethanol and methanol, and slightly soluble in acetone and isopropanol and very slightly soluble in water. The stability of omeprazole is a function of pH; it is rapidly degraded in acid media, but has acceptable stability under alkaline conditions.

Omeprazole is a substituted benzimidazole, 5-methoxy-2-[[(4-methoxy-3, 5-dimethyl-2- pyridinyl) methyl] sulfinyl]-1H- benzimidazole, a compound that inhibits gastric acid secretion.
