Abstract

The invention discloses Lansoprazole medicinal composition tablets and a preparation method thereof. The Lansoprazole medicinal composition tablets comprise the following components in part by mass: 20 to 30 parts of Lansoprazole medicinal composition tablets, 400 to 450 parts of sodium bicarbonate, 100 to 150 parts of calcium hydrophosphate, 600 to 700 parts of magnesium hydroxide, 250 to 500 parts of filler, 40 to 50 parts of disintegrating agent, 50 to 100 parts of flavoring agent, 80 to 100 parts of bonding agent and 20 to 25 parts of lubricating agent. In the Lansoprazole medicinal composition tablets disclosed by the invention, sodium bicarbonate, calcium hydrophosphate and magnesium hydroxide are used in place of enteric coating, the secretion of gastric acid can be inhibited, the Lansoprazole can be prevented from being decomposed by gastric acid, the medicines can be absorbed quickly, and peak concentration can be reached quickly.

Description

technical field [0001] The invention relates to a lansoprazole pharmaceutical composition and a preparation method thereof, in particular to a lansoprazole pharmaceutical composition tablet and a preparation method thereof. Background technique [0002] Lansoprazole (Labsoprazole) is the second proton pump inhibitor anti-ulcer drug in the world after omeprazole. It is a strong inhibitor of the intramembrane proton pump secreted by the parietal cell tip, but Lansoprazole is insoluble In water, it is unstable under acidic conditions and is easily destroyed in gastric acid. The tablets or capsules made in the prior art are slowly absorbed after oral administration, and have low bioavailability and poor stability. [0003] Lansoprazole is usually prepared into enteric-coated tablets or enteric-coated capsules at present, promptly wraps with enteric-coated at the outermost layer of micropill, adds one deck isolation coat between ball core and enteric-coated, to improve formulati...
