Omeprazole enteric coated tablet and preparation method thereof

The invention provides an omeprazole enteric coated tablet and a preparation method thereof. The enteric coated tablet is formed by an inner tablet core and an outer enteric coating, wherein the inner tablet core takes omeprazole as active constituent. No protective isolating layer is arranged between the tablet core and the enteric coating. The inner tablet core is made of omeprazole cyclodextrin inclusion compound and other pharmaceutically acceptable auxiliary materials. The enteric coating contains no plasticizer and the dosage of the enteric coating accounts for 5 percent to 15 percent of the weight of the tablet. The invention has the advantages that the stability and the dissolution of omeprazole are improved, the dosage of basic materials and the dosage of all kinds of inert auxiliary materials are greatly reduced, omeprazole can be stably and rapidly released in the intestinal tract and the bioavailability is improved.
