Compound pseudoephedrine hydrochloride slow release preparation and preparation method thereof
Technical field
The present invention relates to a kind ofly take pseudoephedrine or its physiologically acceptable salt and chlorphenamine or its physiologically acceptable salt as the slow releasing preparation of active component, belong to field of medicaments.
Background technology
Flu is the upper respiratory tract mucosa infection that is caused by a lot of dissimilar viruses, and its cardinal symptom often is nasal obstruction, sneeze, slight throat pain and heating etc., and systemic symptom has whole body discomfort, headache and myalgia etc.Because saying without specific therapy, therefore virus is firm then unnecessary, can only adopt symptomatic treatment to impel many remissions of flu.Because therefore the many symptoms that also do not have a kind of agents alleviate and deposit have various compound preparations to go on the market successively.These compound preparations select the ingredients compound recipe of different curative effects to be used for alleviating simultaneous different symptoms.There is multiple symptom such as patient, particularly at common cold initial stage, then suits the medicine to the illness and use suitable compound preparation than more suitable with several individual event medicines, sometimes also more economical.
Pseudoephedrine claims again d-pseudephedrine, is the optical isomer of ephedrine, and the two is by extracting gained in Herba Ephedrae or the ephedra equisetina grass, but present synthetic.Pseudoephedrine is by stimulating SNE to discharge norepinephrine, indirectly play sympatheticomimetic action, its preventing respiratory is identical with effect and the ephedrine of nasal congestion, but boosting only is 1/5 of ephedrine, strengthening heart rate and pressor effect only is 1/4 of ephedrine, aspect the expansion bronchus smooth muscle only be its 1/2.The pseudoephedrine vasoconstrictive has certain selectivity, mainly shrinks the upper respiratory tract blood vessel and makes smooth breathing, be used for to shrink nasal mucosa vessels alleviating the nasal obstruction symptom, and is evident in efficacy and side effect is little, in the use usually with its hydrochlorate or sulfate.
Chlorphenamine is H
1Receptor antagonist belongs to the antihistamine drug of early stage classics mainly with the treatment anaphylactic disease, is used for the treatment of clinically anaphylactic disease, for example: seasonality and chronic rhinitis, urticaria and pruritus.Usually show in various degree like sympathetic, medmain, calmness and similar cholinolytic side effect, can cause feel sleepy, xerostomia, the dimness of vision etc., common its maleate of using in the use.
Pseudoephedrine and chlorphenamine are prepared into slow releasing preparation, can alleviate owing to heating, headache, upper airway symptoms and the sinusitis that common cold, influenza cause, the various symptoms due to the pollinosis, particularly suitable and the early clinic symptom of alleviating above-mentioned disease are such as symptoms such as sneeze, rhinorrhea, nasal obstructions.Since pseudoephedrine and chlorphenamine using dosage, rate of release, and the difference of the aspects such as absorbance need to provide a kind of both releases, absorption to reach synchronously, in order to better play synergistic compound preparation, reduces the medication number of times and makes things convenient for patient's medication.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome the relevant symptom of flu comprehensively, and all active component all are the compound preparation that slow release discharges.Technical solution of the present invention is as follows:
Slow releasing preparation take pseudoephedrine or its physiologically acceptable salt and chlorphenamine or its physiologically acceptable salt as active component of the present invention, it is characterized in that, described delivery system is comprised of ball core and/or the coating that can make sustained release, and described active component all is present in the ball core.
Slow releasing preparation of the present invention contains pseudoephedrine or its physiologically acceptable salt 30~360mg, preferred 60~240mg in each dosage unit.Chlorphenamine or its physiologically acceptable salt 1~36mg, preferred 2~12mg.
The physiologically acceptable salt of pseudoephedrine of the present invention and the physiologically acceptable salt of chlorphenamine, comprise acylate or inorganic acid salt, wherein the physiologically acceptable salt of pseudoephedrine is preferably hydrochlorate or sulfate, and the physiologically acceptable salt of described chlorphenamine is preferably maleate.
Ball core of the present invention is by hydroxypropyl methylcellulose, the Sulisi aqueous dispersion, the water solublity coating powder, polyvinylpyrrolidone, ethyl cellulose, methylcellulose, Hydroxypropyl Methylcellulose Phathalate, cellulose acetate-phthalate, hydroxypropyl cellulose, carboxymethyl cellulose, sodium carboxymethyl cellulose, hydroxyethyl-cellulose, hexadecanol, Rikemal B 200, stearic acid, glyceryl monostearate, Brazil wax, hydroxy methocel, polyvinyl alcohol, poly-phthalic acid vinyl acetate, polystyrene, carbopol, polrvinyl chloride, octadecanol, diethyl phthalate, dioctyl phthalate, Polyethylene Glycol, sodium alginate, chitosan, gelatin, Lac, pectin, guar gum, sucrose, lactose, starch, dextrin, Icing Sugar, low-substituted hydroxypropyl cellulose, cross linked polyvinyl pyrrolidone, cross-linking sodium carboxymethyl cellulose, mannitol, microcrystalline Cellulose, pregelatinized Starch, in the titanium dioxide one or more are made.
During coating of the present invention is compared by ethyl cellulose, starch, Aquacoat, methylcellulose, acrylic resin, Opadry, Su Li one or more are made.
Preparation of the present invention contain lubricant by magnesium stearate, micropowder silica gel, Pulvis Talci, hydrogenated vegetable oil, polyethylene glycols, month hang in the pure magnesium sulfate one or more.
Preparation of the present invention contains wetting agent by in water, ethanol, dehydrated alcohol, chloroform, acetone, polyvidone, crospolyvinylpyrrolidone, hydroxypropyl methylcellulose and/or other cellulose families one or more.
Preparation of the present invention contains coloring agent by ferrum oxide, amaranth, carmine, erythrosine, new yellow, the light blue of red, the lemon yellow of red, the red pigment of cowberry of red, beet red, lac, capsanthin, red rice, sunset yellow, indigo, and one or more are made for the various pigments that strengthen the acid pigment of above-mentioned water solublity dispersibility in oils and fats.
The release characteristic of pseudoephedrine or its physiologically acceptable salt is in the preparation of the present invention: 1h:20-65%, 2h:40-85%, 4h:60-90%, 8h: be not less than 70%.
The release characteristic of chlorphenamine or its physiologically acceptable salt is in the preparation of the present invention: 1h:30-65%, 2h:40-80%, 4h:60-90%, 8h: be not less than 80%.
Preparation of the present invention is tablet, granule, capsule.
Slow releasing preparation of the present invention, can not only overcome the relevant symptom of flu comprehensively, the effect of performance compound medicine Synergistic, and the release of three kinds of active component of slow releasing preparation of the present invention, absorb and reach synchronously, it obtains desired drug release behavior in vivo and in vitro.Such drug release behavior can reduce takes number of times (by original 4 times on the one reduce to a day twice, namely take night and morning).Therefore this preparation has the advantages that the medication number of times is few, medicine slowly discharges in vivo, blood drug level is steady, fluctuation is little, bioavailability is high, safe.
