Abstract
The present invention provides a production method for arsenic trioxide oral medicinal liquid. The present invention comprises the procedures that 1, arsenic trioxide is weighed and is arranged in a sterile container, and proper sterile water for injection is added in sterile container so as to prepare suspension; 2, the suspension is heated, stirred and dissolved, and proper simple syrup is subsequently added so as to prepare a solution; 3, the pH value of the solution is adjusted to 3 to 5 by citric acid, and the solution is charged via split and sterilized. The present invention also provides arsenic trioxide oral medicinal liquid prepared by the method, and the safety of the arsenic trioxide oral medicinal liquid is superior to that of vein administration.
Description
Technical field
The present invention relates to medicine preparation, especially a kind of arsenic trioxide oral liquid.
Background technology
At present, arsenic trioxide is used for treating the effect of leukemia and other entity tumors extensively to be approved in the world, thereby arsenic trioxide becomes a big focus of leukemia and treatment of solid tumor research.
Studies show that, a small amount of arsenic (lethal dose is 70～180mg/ time) for oral administration can promote the synthetic of protein in body, stimulate bone marrow hematogenesis, help body growth and breeding, and may pass through protoplasmic poison kill tumor cell (referring to Guo Xiaozhuan, poisonous Chinese herbal medicine voluminous dictionary, Tianjin Scientific English Translation publishing house, 1992).
Arsenic trioxide all has significant curative effect to the acute promyelocytic leukemia (APL) with refractory that just control, recurrence, its complete remission rate (CR) is respectively 87.9%, 88.4% and 48.7%, 5 years and 7 probabilities of living in a year reach 90% and 70% respectively (referring to Zhang Peng, Chinese Journal of Hematology, 2000,2).
U.S. FDA official approval arsenic trioxide is used for the treatment of AML, MM, MDS, CML and five indications of APL.Aspect entity tumor, China and all have big quantity research document to prove that it is by following several mechanism of action treatment tumors abroad:
(1) cell death inducing;
(2) suppress the tumor cell vegf expression;
(3) antitumor cell signal conduction;
(4) expression of rise neoplasm metastasis inhibitive factor;
(5) suppress the tumor cell telomerase activation;
(6) artitumor multi-medicine-resistant factor expression etc.
But the production dosage form of the China and the U.S. is the liquid drugs injection type all at present, and it has the following disadvantages:
(1) breakage rate height all has higher breakage rate in producing, transport, store, using;
(2) present arsenic trioxide injection especially below 5 degrees centigrade the time, is easily separated out crystallization when temperature is lower than 16 degrees centigrade, not only cause the character instability, and affect the treatment;
(3) in case liquid drugs injection peace bottle opening just must once be used up, easily cause waste sometimes, the patient considers for economic aspect, uses preserving after once exhaustless liquid drugs injection breaks a seal sometimes, has increased the incidence rate of side effect such as infusion reaction;
The most important thing is that (4) no matter arsenic trioxide is treatment APL or entity tumor, the general treatment method all is once a day, and continuous 30～60 days, certain interval of time carried out next one course of treatment.APL will keep medication 5 years, and other indication administration times also were not less than 1 year, long-time a large amount of intravenously administrable, patient's misery and financial burden (intravenously administrable must be in hospital) have been strengthened, especially for rural patient, go to hospital and abandon keeping treatment owing to inconvenience, cause recurrence and delay treatment.
So the exploitation oral liquid will bring to the patient and greatly facilitate and interests.
Summary of the invention
The invention provides a kind of production method of arsenic trioxide oral liquid, it may further comprise the steps:
(1) takes by weighing arsenic trioxide, place sterile chamber, add an amount of sterile water for injection, make suspension;
(2) with the extremely dissolving of suspension heated and stirred, add an amount of simple syrup again, make solution;
(3) pH value to 3～5 of transferring solution with the acid of Chinese holly edge, the packing sterilization.
In the production method of above-mentioned arsenic trioxide oral liquid, in described step (1), the preferable ratio of using arsenic trioxide and sterile water for injection is 1mg: 1.6ml.
In the production method of above-mentioned arsenic trioxide oral liquid, in described step (2), the simple syrup of preferable adding and the volume ratio of suspension are 0.4: 1.6.
The present invention also provides the arsenic trioxide that is made by aforementioned production method oral liquid.
The specific embodiment
The following examples will be further explained the present invention, but the present invention is not limited only to these embodiment, the scope that these embodiment do not limit the present invention in any way.Some change that those skilled in the art is made within the scope of the claims and adjust also should be thought and belongs to scope of the present invention.
Embodiment 1
The 1000mg arsenic trioxide adds the 1600ml sterile water for injection, and heating for dissolving adds the 400ml simple syrup again, and with Chinese holly edge acid adjust pH to 3.5, the packing sterilization gets final product every bottle of 10ml trioxygen-containingization two arsenic 5mg.
Embodiment 2
The 2000mg arsenic trioxide adds the 3150ml sterile water for injection, and heating for dissolving adds the 850ml simple syrup again, and with Chinese holly edge acid adjust pH to 3.0, the packing sterilization gets final product every bottle of 10ml trioxygen-containingization two arsenic 5mg.
Embodiment 3
The 1000mg arsenic trioxide adds the 1600ml sterile water for injection, and heating for dissolving adds the 400ml simple syrup again, and with Chinese holly edge acid adjust pH to 5.0, the packing sterilization gets final product every bottle of 10ml trioxygen-containingization two arsenic 5mg.
Embodiment 4
The result of animal experiment study shows, the arsenic trioxide oral administration, and the median lethal dose(LD 50) of mice is 23mg/kg, the median lethal dose(LD 50) of the mice of intravenously administrable is 12mg/kg, illustrates that the oral administration safety exceeds one times of intravenously administrable.Suppose that the clinical treatment amount is 10mg/ people's every day, body weight for humans is pressed 60kg and is calculated, i.e. 0.17mg/kg, this amount be about mice median lethal dose(LD 50) 1/135, the safety of visible arsenic trioxide oral liquid is than intravenously administrable height.
The subacute cumulative toxicity of oral administration is measured, and the KC value is greater than 5, and is consistent with intravenously administrable KC value, and prompting does not have marked difference with intravenously administrable aspect cumulative toxicity.
Above experimental result explanation, the safety of arsenic trioxide oral liquid is better than intravenously administrable.
