Embodiment 1

[0027] Embodiment 1 prescription:

[0028]

[0029] Preparation Process:

[0030] Preparation of Blank Ball Cores

[0031] Crush the sucrose and pass through an 80-mesh sieve. Under the condition of high-speed rotation in the centrifugal granulator, gradually spray the adhesive made by adding sucrose, then pass through a 50-mesh sieve, collect the wet blank sugar pellets, and then dry them;

[0032] Drug-containing layer preparation:

[0033] Slowly add hypromellose under stirring in purified water, add vonoprazan fumarate after dissolution is complete, add purified water to the required amount, stir evenly, pass through a 60-mesh sieve to obtain the coating solution, and blank The ball core is placed in a fluidized bed coating device to carry out bottom spraying and drug coating, drying, and passing through a 40-mesh sieve to obtain micro-pills of the main drug layer;

[0034] Isolation layer preparation:

[0035] Slowly add hypromellose under stirring in purified wat...

Abstract

The invention relates to a vonoprazan fumarate enteric-coated capsule and a preparation method thereof, particularly relates to a pellet type vonoprazan fumarate enteric-coated capsule and a preparation method thereof, and belongs to the technical field of medicines. The vonoprazan fumarate enteric-coated capsule sequentially comprises a hollow pill core, a main drug layer, an isolation layer, an enteric layer and a capsule layer from inside to outside, wherein the weight of the main drug layer is 80-130 percent of that of the hollow pill core, the weight of the isolation layer is 10-30 percent of the total weight of the hollow pill layer and the main drug layer, and the weight of the enteric layer is 30-80 percent of the total weight of the hollow pill layer, the main drug layer and the isolation layer. Each capsule contains 10-20mg of vonoprazan. By adopting the technical scheme, the dispersion of vonoprazan fumarate is improved, and the dissolution rate is increased.

Description

technical field [0001] The invention relates to a vonoprazan fumaric acid enteric-coated composition and a preparation method thereof, in particular to a pellet-shaped vonoprazan fumaric acid capsule and a preparation method thereof, which belong to the technical field of medicine. Background technique [0002] Vonoprazan fumarate, its chemical name is: 1-[5-(2-fluorophenyl)-1-(pyridine-3-sulfonyl)-1H-pyrrol-3-yl]-N-methyl Methylamine fumarate, molecular formula: C 17 h 16 FN 3 o 2 S·C 4 h 4 o 4 , molecular weight: 461.4. The chemical formula is shown in formula I. [0003] Formula I [0004] Vonoprazan fumarate belongs to a new class of inhibitors of potassium ion (K) competitive acid blockers (P-CAB), which has a strong and long-lasting inhibitory effect on gastric acid secretion. In one step, it also has an early termination effect on gastric acid secretion by inhibiting the binding effect of K on H,K-ATPase (proton pump). For erosive esophagitis, gastric ulc...
