Description

A kind of R-lansoprazole slowbreak capsule and preparation method thereof
Technical field
The invention belongs to technical field of medicine, be specifically related to a kind of R-lansoprazole slowbreak capsule and preparation method thereof.
Background technology
The molecular formula of R-lansoprazole (dexlansoprazole) is:
Chemistry is by name: (+)-2-[(R)-[[3-methyl-4-(2,2,2-trifluoro ethoxy)-2-pyridine radicals] methyl] sulfinyl]-1H-benzimidazole.
R-lansoprazole is proton pump inhibitor class antiulcerative newly developed, its oral formulations is the exploitation of Japanese Takeda Pharmaceutical Company Limited, commodity are called Kapilax, sustainable gastric acid secretion inhibiting, so can improve GERD symptom, effect significantly and better tolerance, obtains U.S. FDA in January, 2009 and ratifies " heartburn " symptom and the erosive esophagitis that cause for Non-erosive GERD, and for the treatment that maintains of erosive esophagitis.
R-lansoprazole belongs to and draws azole PPIs antiulcerative, in R-lansoprazole structure, there is the chemical constitution of sulfinyl benzimidazole, its stability is subject to light, heavy metal ion, the impact of the many factors such as oxidisability and reproducibility composition, especially in the time of acid condition, can there is destructive variation in the chemical constitution of R-lansoprazole, there is variable color and polymerism, thereby R-lansoprazole is unstable in the diluent of slant acidity, make after oral formulations, drug absorption need be passed through medicine disintegrate dispose procedure, and because causing R-lansoprazole to destroy, decomposes in gastric acid in stomach, and reduction drug effect speed and bioavailability, how making R-lansoprazole capsule mainly under intestinal environment, discharge is very large key point.
Summary of the invention
The invention provides a kind of R-lansoprazole slowbreak capsule and preparation method thereof.
The present invention is by the following technical solutions:
A kind of R-lansoprazole slowbreak capsule, is equipped with two kinds of micropills in capsule, the mass ratio of the first micropill and the second micropill is 1:1-4;
The first micropill is followed successively by celphere, medicated layer, sealing coat and enteric layers from inside to outside, and the mass parts of celphere is 800 parts, and the composition of medicated layer and mass parts are R-lansoprazole: 300 parts,

The preparation method of R-lansoprazole slowbreak capsule, comprises the following steps when preparation:
(1) prepare the first micropill:
A, get each raw material in proportion;
B, each component of medicated layer is mixedly configured into medicated layer coating solution, medicated layer coating solution is added medicine to celphere, dry;
C, bag sealing coat, be mixedly configured into sealing coat coating solution by each component of sealing coat, and the ball core medicine-feeding of sealing coat coating solution to step b gained is dry;
D, bag enteric layers, be configured to enteric layers coating solution by each component of enteric layers, and the ball core medicine-feeding of enteric layers coating solution to step c gained is dry;
(2) prepare the second micropill
Identical with the preparation process of the first micropill;
