The invention belongs to pharmaceutical technology fields, and in particular to a kind of pharmaceutical composition of esomeprazole magnesium, the pharmaceutical composition include: esomeprazole magnesium, sodium bicarbonate, sodium diethyldithiocarbamate.Experiments have shown that pharmaceutical composition of the present invention is prepared into preparation, esomeprazole magnesium dissolution rate is significantly improved, and has better stability.
Description
Technical field
The invention belongs to pharmaceutical technology fields, and in particular to the pharmaceutical composition and its preparation of a kind of esomeprazole magnesium and
The preparation method of preparation.
Background technique
Esomeprazole is the S- isomers of Omeprazole, reduces gastric acid secretion to mechanism of action by the rake of specificity,
For the specific inhibitor of proton pump in parietal cell.Site of action and mechanism are the height that esomeprazole secretes sour micro-pipe in parietal cell
Concentration and it is converted into active form in acid environment, to inhibit the H at the position+/k+- ATP (proton pump), to basal gastric acid secretion
Gastric acid secretion with stimulation generates inhibition.
Esomeprazole magnesium is the proton pump inhibitor that first development is isomers, by AstraZeneca pharmaceutical Co. Ltd
It develops, is ratified to list by FDA in March, 2005, dosage form is injection, the resistance to letter of trade name.It has been widely used in facing
Bed is the choice drug for treating the acid related disorders such as peptic ulcer, gastroesophageal reflux disease.Esomeprazole magnesium as magnesium salts,
Favorable solubility in water.Esomeprazole magnesium is alkaline matter simultaneously, is stablized to alkali, meets acid and is easily degraded, also unstable to oxygen
It is fixed, therefore the esomeprazole magnesium preparation listed before this is enteric coated preparations, protects a drug from acid degradation using enteric coated,
But it has delayed the absorption of drug and the initial inhibiting effect to gastric acid, is unfavorable for treating and releasing patient suffering in time.
Chinese patent CN102078616A discloses a kind of esomeprazole sodium bicarbonate composition, wherein esomeprazole
Magnesium salts 20-40mg, sodium bicarbonate 1100-1680mg and other adjunct ingredients are incorporated into a kind of fixed unit dosage forms, the combination
Object works comparatively fast, but acid resistance is weaker, influences dissolution of the esomeprazole in acid.
Summary of the invention
In order to solve the above technical problems, applicant is with sodium bicarbonate, sodium diethyldithiocarbamate by research
Auxiliary material is prepared into preparation, and the dissolution rate in acid significantly improves, and guarantees that the stability of product, the quality of the pharmaceutical preparations are met the quality standard
Requirement.
What the present invention was achieved through the following technical solutions.
A kind of pharmaceutical composition of esomeprazole magnesium, pharmaceutical composition include: esomeprazole magnesium, sodium bicarbonate,
Sodium diethyldithiocarbamate.
Pharmaceutical composition described above, contains: esomeprazole magnesium, sodium bicarbonate, diethyldithiocar bamic acid

Specific embodiment
Test example 1: screening test
1 group of drug: esomeprazole magnesium 4g, sodium bicarbonate 72.1g;
2 groups of drug: esomeprazole magnesium 4g, sodium bicarbonate 72.1g, sodium diethyldithiocarbamate 0.1g;
3 groups of drug: esomeprazole magnesium 4g, sodium bicarbonate 72.1g, sodium diethyldithiocarbamate 0.2g;
Preparation method: (1) crossing 80 meshes for esomeprazole magnesium, sodium bicarbonate, crosslinked polyvinylpyrrolidone 6.5g, mixes
It closes;(2) sodium diethyldithiocarbamate is added into step (1) resulting mixture, is uniformly mixed;(3) to step (2)
Copolyvidone 45g, granulation are added in resulting mixture;(4) magnesium stearate 0.65g is added to the mixture of step (3), mixes
, granule is obtained.
Two the second method of the annex XC measurements of version in 2010 of [dissolution determination] Chinese Pharmacopoeia.
Each prescription dissolution determination result of table 1
Dissolution rate (%) | Prescription 1 | Prescription 2 | Prescription 3 | Prescription 4 |
Esomeprazole magnesium | 85.3 | 99.8 | 99.9 | 94.3 |
Sodium bicarbonate | 92.4 | 99.9 | 99.9 | 96.7 |
Conclusion: as seen from the above table, the dissolution of esomeprazole magnesium granule after sodium diethyldithiocarbamate is used
Property significantly improves, but when in sodium diethyldithiocarbamate weight a certain range esomeprazole magnesium granule solubility
It reduces instead.
Test example 2: influence factor test
[related substance] is protected from light operation.It takes this product fine powder appropriate (being approximately equivalent to esomeprazole magnesium 20mg), sets 100ml amount
