Abstract
The invention discloses a dextromethorphan hydrobromide dripping pill, which is formed by heating and co-melting dextromethorphan hydrobromide, polyethylene glycol, glycerol and tween-80, and dripping the dextromethorphan hydrobromide, the polyethylene glycol, the glycerol and the tween-80 into methyl silicone oil condensate while keeping the co-melting state. The dextromethorphan hydrobromide dripping pill has simple preparation process and low cost, and has dissolution rate of 90% of the marked amount within 15 min and higher than that of tablet. The dripping pill can be dissolved in water, and can be used as a substitute for solution, and has far better stability than solution.
Description
Technical field
The present invention relates to a kind of preparation reform of common drug, particularly a kind of dextromethorphan hydrobromide drop pill.The invention still further relates to the preparation method of above-mentioned drop pill.
Background technology
Dextromethorphan hydrobromide is as a kind of common drug, and its traditional dosage form is a tablet, and the dissolution of this tablet is generally when being limited to 30 minutes, and stripping quantity is 80% of a labelled amount.Simultaneously in the production process of tablet, there is dust pollution, and the production equipment complexity, floor space is big, and cost is higher.Also have a kind of Dextromethorphan Hydrobromide Solution preparation in addition, it can be for child administration, but also has inconvenience and the bad problem of stability of carrying.
And dropping pill formulation is as a kind of novel medicament preparation, and is easy because of production equipment, floor space is little, and has no dust and the low characteristics of cost, the most important thing is that the dissolution of drop pill generally all is higher than tablet.Therefore, the drop pill of various medicines occurs in succession, and the melt temperature of dextromethorphan hydrobromide is 125 degrees centigrade, and near the dulling temperature, therefore directly dripping the pill agent with the heat fusing method influences stability of drug.The present invention is by form improvement, and the form of drop pill is made in dextromethorphan hydrobromide and dressing congruent melting, kept stability of drug.
Summary of the invention
The object of the present invention is to provide a kind of dextromethorphan hydrobromide drop pill, is a kind of new Suppress.The present invention provides the preparation method of above-mentioned drop pill simultaneously, and this kind medicine is carried out the preparation reform.
Dextromethorphan hydrobromide drop pill of the present invention is that dextromethorphan hydrobromide and Polyethylene Glycol, glycerol, tween 80 are heated congruent melting, keeps the congruent melting state to splash into the drop pill that forms in the methyl-silicone oil condensed fluid.
Can contain the hydrobromic acid dextromethorphan in the above-mentioned every ball of this drop pill and be 7.5 milligrams, polyethylene glycol 6000 and be 15 milligrams, cetomacrogol 1000 0 and be 7.5 milligrams, 3.8 milligrams of glycerol, tween 80 is 0.56 milligram.
The preparation method of above-mentioned dextromethorphan hydrobromide drop pill may further comprise the steps:
A: batching: drop pill dosage and drop pill number by the desire preparation take by weighing raw material and mixing respectively;
B: congruent melting: heat and remain on 85 degrees centigrade of stirrings, mixed material is fully mixed and be the uniform colloidal state of fusing;
C: the system of dripping: above-mentioned colloidal state eutectic is remained on 85 degrees centigrade splash into and be condensed into drop pill in the methyl-silicone oil.
After said process finished, what this preparation process also comprised drop pill removed silicone oil, drying and coating process.
The temperature that keeps in this congruent melting and the system process preferably all is 85 degrees centigrade.
Dextromethorphan hydrobromide drop pill of the present invention, preparation method is simple, and cost is lower, and the dissolution of this drop pill can reach 90% of labelled amount in 15 minutes simultaneously, and dissolution is higher than tablet.This drop pill water soluble can replace solution to use, and stability but is better than solution far away.And success overcome the problem that melt temperature easy dulling influences stability of drug.
The specific embodiment
Present embodiment is that 7.5 milligrams dextromethorphan hydrobromide drop pill is an example to prepare 1000 content.
Take by weighing 7.5 gram dextromethorphan hydrobromides respectively, 15 gram polyethylene glycol 6000s, 7.5 gram cetomacrogol 1000s, 0,3.8 gram glycerol and 0.56 gram tween 80.Put into the container mix homogeneously, be heated to 85 degree, and remain on this temperature continuation stirring, make material be uniform molten state fully.
Material that then will above-mentioned molten state drips to be made in the methyl-silicone oil, makes its condensation formation ball shape.Above-mentioned material can drip 1000 pills of restriction, and every pill contains 7.5 milligrams of hydrobromic acid dextromethorphan effective ingredient.
Then the drop pill in the above-mentioned silicone oil is taken out, and remove silicone oil, form the finished product drop pill behind drying, the coating.
The fusion point of the dextromethorphan hydrobromide that the present invention uses is 125 degrees centigrade, as adopt fusion method that dextromethorphan hydrobromide is added in the fused Polyethylene Glycol, near " dulling " temperature, be easy to generate " dulling " phenomenon when being heated to 125 degrees centigrade, be unfavorable for the stable of medicine.And dextromethorphan hydrobromide very easily is dissolved in the glycerol in the time of 85 degrees centigrade.Therefore the present invention adopts and in the time of 85 degrees centigrade dextromethorphan hydrobromide is dissolved in glycerol and the Polyethylene Glycol, stirs and forms fused molecular solution, and coprecipitated again is colloidal state, belongs to solid dispersion, makes the efficacy stability of dextromethorphan hydrobromide.
The dissolution of drop pill of the present invention can reach in the time of 15 minutes, and stripping quantity reaches more than 90% of labelled amount, and its dissolution is significantly better than tablet.The dissolution that passes through six months effective ingredient of accelerated test when relative humidity 75% (40 degrees centigrade and) does not simultaneously change.And this drop pill can be water-soluble, forms solution, can be used as solution and take.
