Abstract
The invention relates to a medicinal composition containing a meglumine cyclic adenosine monophosphate compound, and in particular relates to freeze-dried injection of meglumine cyclic adenosine monophosphate and a preparation method thereof. Each 1,000 injections are prepared from the following components: 20g of meglumine cyclic adenosine monophosphate, 100 to 200g of mannitol, 1 to 3g of ethylene diamine tetraacetic acid (EDTA) calcium, 1 to 2g of vitamin C, and 2,000ml of a buffer solution of disodium hydrogen citrate and trisodium citrate at a mole ratio of 1: 4.
Description
Technical field
The present invention relates to freeze-dried powder of a kind of meglumine adenosine cycle phosphate and preparation method thereof, belong to field of medicaments.
Background technology
Meglumine adenosine cycle phosphate, English name: Meglumine Adenosine Cyclophosphate is the salt of adenosine cyclophosphate and meglumine (1:1).Meglumine adenosine cycle phosphate is non-digitalis cardiac tonic, has positive inotropic action, can strengthen myocardial contraction, improves myocardium blood-pumping function, and the blood vessel dilating effect is arranged, and can reduce myocardial oxygen consumption; Improve the myocardial cell metabolism, the cardiac muscle of protection ischemia, anoxia; Can improve sinuatrial node P cell function.
Meglumine adenosine cycle phosphate enters human body, half-life in blood is 60~150min, because it has preferably hydrophilic, especially fat-soluble stronger, easily enter in the myocardial cell through fat-soluble cell membrane and play a role, being decomposed to form 5-AMP through phosphodiesterase, is adenosine and phosphoric acid through the 5-AMP enzymatic degradation again.Meglumine adenosine cycle phosphate begins effect behind 10~20min after the medication, the drug effect extinction time was at 6~8 hours at 1~2 hour rush hour for produce effects.
The meglumine adenosine cycle phosphate injection that has gone on the market has the lyophilization injectable powder, soluble in water because of meglumine adenosine cycle phosphate, generally only use mannitol as filler in its prescription, but find in the practice, the problem of color jaundice is arranged after the existing medicament long storage time, need low temperature storage.Some product dissolution velocity in clinical use procedure is undesirable, causes and uses inconvenience, the invention provides a kind of new prescription and preparation method, and the medicament long storage time also can not turned to be yellow, and dissolution velocity is improved.
Summary of the invention
The invention provides a kind of pharmaceutical composition that contains the meglumine adenosine cycle phosphate chemical compound, is the injection freeze-dried pharmaceutical formulation take meglumine adenosine cycle phosphate as active component, per 1000 injections, and it is composed as follows:
Meglumine adenosine cycle phosphate 20g;
Mannitol 100-200g;
EDTA calcium 1-3g;
Vitamin C 1-2g,
Mol ratio is DisodiumHydrogen Citrate and the trisodium citrate buffer 1000ml of 1:4;
All the other are water for injection.
Compositions of the present invention, most preferred prescription is: per 1000 injections, it is composed as follows:
Meglumine adenosine cycle phosphate 20g;
Mannitol 150g;
EDTA calcium 2g;
Vitamin C 1.5g,
Mol ratio is DisodiumHydrogen Citrate and the trisodium citrate buffer 2000ml of 1:4,
Wherein, the compound method of DisodiumHydrogen Citrate and trisodium citrate buffer is as follows: take by weighing DisodiumHydrogen Citrate 13g, trisodium citrate 60g is dissolved in the buffer solution that obtains pH value 7.0 in the 1000ml water for injection.Compositions of the present invention, its preparation method is as follows: prepare first DisodiumHydrogen Citrate and trisodium citrate buffer 2000ml, then get meglumine adenosine cycle phosphate, mannitol, EDTA calcium, vitamin C adds mixed dissolution in DisodiumHydrogen Citrate and the trisodium citrate buffer, the filter membrane of via hole diameter molecular cut off 20000 filters, fill, half tamponade, lyophilization, and get final product.
The present invention has used DisodiumHydrogen Citrate and trisodium citrate buffer to make the solution pH value that obtains of the present invention remain on 6.9-7.1, and fluctuation range is minimum, guarantees its stability.
Adopt High-dose Mannitol that the powder dissolution speed after the lyophilizing is accelerated, use EDTA calcium and vitamin C to guarantee that it places in use the long period and also can not change, guarantee its stability.
Compositions of the present invention, its prescription obtains through screening, and wherein most preferred prescription forms, referring to embodiment 1.Screening process is as follows:
Table 1: the prescription screening experiment take dissolution time as index
Experimental technique:
The above medicine of prescription, wiring solution-forming, the capacity of packing into are the 5ml ampulla, are prepared into lyophilized formulations with the method for embodiment 1, carry out again dissolution experiment.
Sample:
Each 10 bottles in the sample of each prescription, every bottle adds sodium chloride for injection solution 5ml, with hand moving.
The dissolving index:
Naked eyes are seen without floccule and are existed for whole dissolvings.
Table 2 is investigated embodiment 1 and the indices result of the meglumine adenosine cycle phosphate sample that gone on the market
Embodiment 1 sample | The meglumine adenosine cycle phosphate sample that has gone on the market | |
Mouldability | Good | Generally |
Dissolubility | Good | Generally |
Water content | 5.02% | 4.89% |
Condition of storage | Room temperature | 4-8℃ |
As seen from table, embodiment 1 is better than reference substance.
Table, 3 investigate embodiment 1 and three batches in the meglumine cyclic adenosine for injecta sample that gone on the market, detection heavy metal and impurity content
From test data, the three batches of injection heavy metals and the impurity content of embodiment 1 are less than the medicine that has gone on the market.
Another experimental group room temperature was placed 90 days, detected three batches of heavy metal and impurity contents, result such as following table again:
From test data, the three batches of injection heavy metals and the impurity content of embodiment 1 obviously are less than the medicine that has gone on the market.
The laboratory sample room temperature was placed 60 days in addition, and the fluctuation range of embodiment 1 solution pH value is 6.9-7.1, and the meglumine adenosine cycle phosphate that has gone on the market is 6.7~7.4.
The dissolution velocity test:
Carry out the dissolution velocity test with the lyophilized injectable powder of the present invention of the method for the embodiment of the invention 1 preparation and the meglumine adenosine cycle phosphate lyophilized injectable powder that has gone on the market, result's demonstration, the product dissolution velocity of the embodiment of the invention 1 is higher than matched group.
The storage-stable test
Embodiment 1 and the meglumine adenosine cycle phosphate lyophilized injectable powder that gone on the market the lower storage of conventional refrigeration temperature (2-8 ℃) 18 months, take impurity as investigating index, are carried out long-time stability and investigate test.The results are shown in following table:
Different prescriptions long-time stability under 2-8 ℃ of holding conditions
Minute | Embodiment 1 | The meglumine adenosine cycle phosphate lyophilized injectable powder that has gone on the market |
0 month | 0.81% | 0.62% |
June | 0.99% | 0.94% |
December | 1.05% | 1.36% |
18 months | 1.19% | 1.56% |
The content of drug standard requirement impurity should be greater than 1.5%.By table as seen, the sample of the more commercially available formula preparation of the present invention is more stable, can be 2~8 ℃ of lower storages of conventional refrigeration temperature 18 months, and product quality still meets the national drug standards, and contrast can only store 12 months.
To the freeze dried injection that contains meglumine adenosine cycle phosphate of buying on the market of the present invention.Carried out the research of stability test, the result shows that stability of the present invention is better than the product on the market.
New meglumine cyclic adenosine for injecta freeze-drying medicinal composition provided by the invention has good stability, and invariant color does not stimulate during injection, and better tolerance is dissolved the multiple advantages such as rapid, easy to use, satisfies greatly patient's needs.
