Abstract

The invention discloses an omeprazole hydrotalcite composite tablet and a preparation process thereof. The omeprazole hydrotalcite composite tablet is of a three-layer composite structure of an omeprazole tablet core layer, an enteric layer and a hydrotalcite layer which are sequentially pressed from inside to outside. The preparation process comprises the following steps: firstly, pressing omeprazole and auxiliary materials into a tablet core; then, directly carrying out secondary pressing by using hydroxypropyl methylcellulose phthalate and the tablet core, and pressing the enteric layer; and finally, carrying out third-time pressing on hydrotalcite, the auxiliary materials and the tablet core subjected to secondary pressing to obtain a pressed tablet of an omeprazole, enteric layer and hydrotalcite quick-acting layer. After a patient takes the composite tablet, the hydrotalcite layer in the medicine is rapidly disintegrated, the concentration of gastric acid is rapidly reduced, the pain of the patient is reduced, then the omeprazole wrapping the enteric layer enters the intestinal tract to be released, the gastric acid release capacity of gastric cells is reduced, and the symptoms are treated firstly and then the cost is reduced.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to an omeprazole aluminum magnesium carbonate composite tablet and a preparation process thereof. Background technique [0002] Oral tablet delivery is a matter of concern as the average human lifespan increases and swallowing ability declines with age. It is estimated that about 50% of the population has difficulty swallowing tablets and capsules, affecting compliance with drug therapy. Usually, patients with omeprazole and aluminum magnesium carbonate need to take them separately, which will cause the pain of taking the medicine twice. [0003] At present, most prazole drugs are coated to form an enteric layer. The coating cannot cover all the coating liquid, and there will be a large loss. At the same time, the air discharged from the coating machine will cause large pollution. , Even with air cleaning equipment, the air pollution problem cannot be completely eliminat...
