At present, there is not yet correlational study diphenhydramine, vinpocetine being used for treatment of myocardial infarction, also do not have correlational study report diphenhydramine, vinpocetine and nicotinic acid collocation adenosine cyclophosphate being used for the treatment of myocardial infarction.
Summary of the invention
The object of this invention is to provide a kind of be used for the treatment of myocardial infarction, containing the compositions of adenosine cyclophosphate.
Another object of the present invention is to provide the application of above-mentioned composition in preparation treatment myocardial infarction medicine.
Above-mentioned purpose of the present invention is achieved by following scheme:
Containing a compositions for adenosine cyclophosphate, the formula of said composition is made up of each component of following parts by weight:
The preferred version of combinations thereof composition formula is as follows:
The preparation method of the above-mentioned compositions containing adenosine cyclophosphate is as follows:
Adenosine cyclophosphate, diphenhydramine, vinpocetine and nicotinic acid are ground respectively and after crossing 100 mesh sieves, according to formula consumption, mixing, drier 30 minutes of the baking oven putting into 55-60 DEG C, then prepare the compositions containing adenosine cyclophosphate of the present invention.
The above-mentioned compositions containing adenosine cyclophosphate can make various dosage form with pharmaceutically acceptable carrier or excipient, as tablet, granule, capsule or injection etc.
Compositions containing adenosine cyclophosphate of the present invention, through experimentation, has well treatment myocardial infarction effect, therefore, can be used for the medicine preparing treatment myocardial infarction.
Compared with prior art, the present invention has following beneficial effect:
1. the compositions containing adenosine cyclophosphate of the present invention, introduces diphenhydramine, vinpocetine in the research for the treatment of myocardial infarction medicine first, by by adenosine cyclophosphate, diphenhydramine, vinpocetine and nicotinic acid compatibility, serves the effect for the treatment of myocardial infarction well;
2. the compositions containing adenosine cyclophosphate of the present invention, in its formula, each composition is all that basic research and clinical practice confirm do not have obvious toxic-side effects, and does not have the taboo of compatibility between each composition, without mutual ill effect, therefore has safety.
Detailed description of the invention
Below in conjunction with specific embodiment the present invention done and describe further, but specific embodiment does not do any restriction to the present invention.
Embodiment 1
Compositions containing adenosine cyclophosphate of the present invention, the formula of said composition is made up of each component of following parts by weight:
The preparation method of the above-mentioned compositions containing adenosine cyclophosphate is as follows:
Adenosine cyclophosphate, diphenhydramine, vinpocetine and nicotinic acid are ground respectively and after crossing 100 mesh sieves, according to formula consumption, mixing, drier 30 minutes of the baking oven putting into 55-60 DEG C, then prepare the compositions containing adenosine cyclophosphate of the present embodiment.
Embodiment 2
Compositions containing adenosine cyclophosphate of the present invention, the formula of said composition is made up of each component of following parts by weight:
The preparation method of the above-mentioned compositions containing adenosine cyclophosphate is as follows:
Adenosine cyclophosphate, diphenhydramine, vinpocetine and nicotinic acid are ground respectively and after crossing 100 mesh sieves, according to formula consumption, mixing, drier 30 minutes of the baking oven putting into 55-60 DEG C, then prepare the compositions containing adenosine cyclophosphate of the present embodiment.
Embodiment 3
Compositions containing adenosine cyclophosphate of the present invention, the formula of said composition is made up of each component of following parts by weight:
The preparation method of the above-mentioned compositions containing adenosine cyclophosphate is as follows:
Adenosine cyclophosphate, diphenhydramine, vinpocetine and nicotinic acid are ground respectively and after crossing 100 mesh sieves, according to formula consumption, mixing, drier 30 minutes of the baking oven putting into 55-60 DEG C, then prepare the compositions containing adenosine cyclophosphate of the present embodiment.
Comparative example 1
The compositions of this comparative example, its formula is made up of each component of following parts by weight:
Diphenhydramine 8 parts;
Vinpocetine 6 parts;
2 parts, nicotinic acid.
The preparation method of above-mentioned composition is as follows:
Diphenhydramine, vinpocetine and nicotinic acid are ground respectively and after crossing 100 mesh sieves, according to formula consumption, mixing, drier 30 minutes of the baking oven putting into 55-60 DEG C, then prepare the compositions of this comparative example.
Embodiment 4 myocardial infarction model is tested
Take mice as experimental subject, often organize 10 mices, establish 6 groups altogether, shown in specific as follows:
(1) blank group: experimental drug is water for injection.
(2) experimental group 1: experimental drug is a kind of compositions containing adenosine cyclophosphate prepared by embodiment 1;
(3) experimental group 2: experimental drug is a kind of compositions containing adenosine cyclophosphate prepared by embodiment 2;
(4) experimental group 3: experimental drug is a kind of compositions containing adenosine cyclophosphate prepared by embodiment 3;
(5) matched group 1: experimental drug is compositions prepared by comparative example 1;
(6) matched group 2: experimental drug is adenosine cyclophosphate.
Experimental model is myocardial infarction model, after causing each group of experiment mice myocardial necrosis with isoproterenol, and intravenously administrable, twice daily, the dosage of each experimental drug is 5mg/kg, and administration is after 20 days, observe mice survival rate (%), result is as follows:
(1) blank group: survival rate 0;
(2) experimental group 1: survival rate 90%;
(3) experimental group 2: survival rate 90%;
(4) experimental group 3: survival rate 100%;
(5) matched group 1: survival rate 20%;
(6) matched group 2: survival rate 70%.
As can be seen from above-mentioned experimental result, as compared to using merely adenosine cyclophosphate or use diphenhydramine, vinpocetine to combine with nicotinic acid, the compositions containing adenosine cyclophosphate of the present invention has the effect of well treatment myocardial infarction.
