Abstract
The invention belongs to the technical field of medicinal preparation and relates to a compound zinc gluconateand ibuprofen granule capable of curing the cold and a preparation method thereof. The compound zinc gluconateand ibuprofen granule is composed of brufen cyclodextrin clathrate compound, gluconic acid zinc, chlorpheniramine, diluents and adhesives, wherein dosage molar ratio of brufen and cyclodextrin in the brufen cyclodextrin clathrate compound is 1:1 to 1:2, weight ratio of the brufen, gluconic acid zinc and chlorpheniramine is 1:(0.4-0.8):(0.01-0.03), dosage of the diluents is 15% to 40% of the whole weight of the compound zinc gluconateand ibuprofen granule, and dosage of the adhesives is 2% to 6% of the whole weight of the compound zinc gluconateand ibuprofen granule. The compound zinc gluconateand ibuprofen granule is good in taste, simultaneously resolves the problem that brufen blood concentration is large in fluctuation after patients take the compound zinc gluconateand ibuprofen granule, and effectively reduces side effects.
Description
Technical field
The invention belongs to technical field of medicine, relate to a kind of Compound Zinc cloth granule for the treatment of flu and preparation method thereof, Compound Zinc cloth granule that particularly the ibuprofen blood concentration fluctuation is less, side effect is little in a kind of rear patient's body of taking medicine and preparation method thereof.
Background technology
Ibuprofen (Ibuprofen) is one of the most successful ntipyretic analgesic medicine of development in recent years, and China has classified ibuprofen as the pillar product of realizing that the antipyretic analgesic breed structure upgrades.It except antiinflammatory action, again tool ease pain significantly, antipyretic effect and good safety; Its antiinflammation is than the large 16-32 of aspirin times, and large 20 times of refrigeration function, the large 16-32 of analgesic activity are doubly; The effect of bringing down a fever is than the principal item in the antipyretic analgesic---and aspirin, acetaminophen are fast and lasting.The patient takes behind this medicine often by the untoward reaction of symptom of digestive tract, comprises dyspepsia, stomach burn feeling, stomachache, feels sick, vomiting.Zinc gluconate (Zinc Gluconate) is separated into zinc ion and gluconic acid in vivo, participates in synthetic and multiple Enzyme Production and the activation of ribonucleic acid and DNA (deoxyribonucleic acid), and the effect that strengthens cytophagous phagocytic activity is arranged.Current research shows that zinc ion all has obvious curative effect at aspects such as preventing cold virus breeding, shortening flu pathogenic process.Chlorphenamine maleate (Chlorphenamine Maleate) is antihistaminic, has competitive blocking histamine H1 receptor and to antfhistamine effect, it also has the effect of anti-M cholinoceptor, reduce the nasal mucosa secretion, can obviously eliminate the watery nasal discharge, sneeze, the nasal congestion that are caused by flu, shed tears and throat's allergic symptom such as itch.
Ibuprofen, zinc gluconate and chlorphenamine maleate use in conjunction have significant synergism when treatment common cold or influenza, be a comprehensive compound medicine of therapeutic effect.For the compound preparation of these three medicines, gone on the market or bibliographical information arranged Compound Zinc cloth granule, zinc cloth sheet (conventional tablet), Luo Fen Portugal zinc that quick dispersible tablet and compound soft capsule preparation arranged.Yet, because the Half-life in vivo of ibuprofen is 1.8-2 hour, the adult need take 150 milligrams at every turn, take every day 3 times, cause the dosage of ibuprofen in the existing Compound Zinc granule large, and the ibuprofen in the preparation discharges too fast in human body, causes blood concentration fluctuation larger, has brought comparatively serious dyspepsia, stomach burn feeling, stomachache, feels sick, the side effect such as vomiting.Therefore, need the Compound Zinc cloth preparation that the ibuprofen blood concentration fluctuation is less, side effect is little in a kind of rear patient's body of taking medicine of invention.
Summary of the invention
The purpose of this invention is to provide a kind of Compound Zinc cloth granule for the treatment of flu.
Another object of the present invention provides the preparation method of the Compound Zinc cloth granule for the treatment of flu.
The present invention is achieved through the following technical solutions.
One, a kind of Compound Zinc cloth granule for the treatment of flu, a kind of Compound Zinc cloth granule for the treatment of flu, it is characterized in that: formed by ibuprofen cyclodextrin clathrate, zinc gluconate, chlorphenamine maleate, diluent and binding agent, the consumption mol ratio of ibuprofen and cyclodextrin is 1:1～1:2 in the wherein said ibuprofen cyclodextrin clathrate, the weight ratio of ibuprofen, zinc gluconate and chlorphenamine maleate is 1:0.4-0.8:0.01-0.03, the diluent consumption accounts for 15%～40% of granule gross weight, and binder dosage accounts for 2%～6% of granule gross weight.
Described cyclodextrin is beta-schardinger dextrin-.
Further, the weight ratio of described ibuprofen, zinc gluconate and chlorphenamine maleate is 1:0.5:0.01.
Described diluent is selected from one or more of microcrystalline Cellulose, micropowder silica gel, Icing Sugar and sucrose.
Described binding agent is selected from hydroxypropyl cellulose or/and sodium carboxymethyl cellulose.
Two, the preparation method of the Compound Zinc cloth granule for the treatment of flu of the present invention comprises the steps:
(1) with 50 ℃ of ibuprofen, zinc gluconate, chlorphenamine maleate, beta-schardinger dextrin-, diluent and binding agents dry 3 hours respectively, it was for subsequent use to cross 100 mesh sieves;
(2) beta-schardinger dextrin-is added water, under 45 ~ 60 ℃ temperature conditions, stir under the rotating speed of 750r/min ~ 3000r/min and make saturated aqueous solution;
(3) ibuprofen being dissolved in weight ratio is 50% acetonitrile solution, and then the speed with 1 ~ 3mL/min is added drop-wise in the saturated beta-schardinger dextrin-aqueous solution of above-mentioned preparation, and continuation was stirred 3 hours after finishing, and spray drying makes cyclodextrin clathrate;
(4) described cyclodextrin clathrate is crossed 100 mesh sieves, then with zinc gluconate, chlorphenamine maleate, diluent, binding agent mix homogeneously after soft material processed, cross 20 mesh sieves wet granular processed, 45 ~ 60 ℃ of wet granulars is fully dry, cross 20 mesh sieve granulate and obtain Compound Zinc cloth granule.
Compared with prior art, the present invention has following advantage and marked improvement:
1, overcome the problem that ibuprofen can't steadily discharge in the Compound Zinc cloth granule of prior art.Compound Zinc cloth granule of the present invention in vivo can be fast, steadily discharge, take effect immediately after on the one hand the patient being taken medicine, reduced on the other hand medicine to the gastrointestinal zest, and can keep relatively constant drug level, reduce potential toxic and side effects, prolonged the action time of medicine.Stripping feature by embodiment 4 is investigated result of the test and can be found out, zinc cloth granule of the present invention and plain particles in 30min the time accumulation dissolution meet the stripping requirement of granule all greater than 80%.Yet comparative example's granule is too fast at front 15min rate of release, fluctuating widely of drug level occur easily in patient body, causes untoward reaction.And the zinc cloth granule of the present invention's preparation discharges steadily, can effectively avoid the peak valley phenomenon of medicine, reduces the untoward reaction that causes because blood drug level is too high.
2, overcome the problem of the zinc cloth granule heavy bitter taste of prior art.Can cover well the bitterness of ibuprofen by the zinc cloth granule of cyclodextrin inclusion compound, the compliance, particularly old man, child etc. that have increased patient's medication are swallowed inconvenient patient.
