Description

The pharmaceutical composition that is used for the treatment of hyperuricemia
Technical field
The present invention relates to be used for the treatment of the pharmaceutical composition of hyperuricemia Febustat and uricosuric eccritic treatment hyperuricemia, more particularly, the present invention relates to the pharmaceutical composition of Febustat or derivatives thereof and benzbromarone, it is used for the treatment of disease relevant with hyperuricemia and gout.
Background technology
Along with the raising of expanding economy and people's living standard, life style and dietary structure change and numerous disease all causes hyperuricemia (Hyperuricemia), and its sickness rate raises year by year, and the trend that becomes younger.Hyperuricemia is the same with other metabolic diseases, and sickness rate is in rising trend in recent years, and has increased the case fatality rate of cardiovascular and cerebrovascular disease.Hyperuricemia comprises former and secondary hyperuricemia.Will form urate when hyperuricemia reaches certain high value, crystallization causes the goat outbreak in tissue, articular cavity deposition.Hyperuricemia also can cause gouty arthritis, gouty nephropathy and renal calculus.Evidence show that simultaneously hyperuricemia and hypertension, coronary heart disease, diabetes, hyperlipemia, hypercoagulability, obesity etc. are closely related, is the important component part of metabolism syndrome.They can interact, and form vicious cycle, and people's healthy and life security in serious threat.
Reduce blood plasma and organize uric acid level to become the key link of containment gout and above-mentioned disease progression.The medicine of the gout of uric acid resisting treatment at present mainly contains two big class medicines:
(1) reduce the medicine of uricopoiesis, for example allopurinol, Febustat (febuxostat) etc., they are by the activity that suppresses xanthine oxidase uricopoiesis to be reduced, thereby reduce the uric acid content in blood and the urine.The important part that Febustat is different from allopurinol is that it has specific inhibitory effect to xanthine oxidase, and allopurinol is a competitive inhibition.But have data to show, heavy dose of Febustat has tangible detrimental effect to liver function.
(2) medicine of uricosuric eccritic, for example probenecid (probenecid), benzbromarone (benzbromarone) and sulphinpyrazone (sulfinpyrazone) or the like, but they all have in various degree side effect and toxicity, during particularly with heavy dose of the use, can damage human body.
Summary of the invention
Inventor of the present invention is surprised to find by zoopery: the pharmaceutical composition that Febustat or derivatives thereof and benzbromarone are formed with the ratio of 1:1-4 has beyond thought synergism, it to be single can reducing uric acid concentration in the serum fast and significantly with much lower dosage use than their, thereby treats hyperuricemia effectively.Therefore, this pharmaceutical composition be particularly suitable for treating hyperuricemia and with its diseases associated, for example acute and chronic gout.Therefore,
An object of the present invention is to provide a kind of pharmaceutical composition that is used for the treatment of hyperuricemia.
Another object of the present invention provides this pharmaceutical composition at the preparation treatment hyperuricemia various diseases relevant with it, the application in the medicine of particularly acute and chronic gout.
The invention provides a kind of pharmaceutical composition that is used for the treatment of hyperuricemia, said composition comprises Febustat or derivatives thereof and benzbromarone and pharmaceutically useful carrier; Febustat or derivatives thereof wherein: benzbromarone: the ratio of weight and number of acceptable pharmaceutical carrier is 1:1~4:0.5~100.The ratio of weight and number of preferred Febustat or derivatives thereof and benzbromarone is 1:1-4, preferred especially 1:2-4.
In a particularly preferred example of the present invention, the ratio of weight and number of Febustat or derivatives thereof and benzbromarone is 1:2.
In another particularly preferred example of the present invention, the ratio of weight and number of Febustat or derivatives thereof and benzbromarone is 1:4.
Febustat derivant of the present invention not only comprises Febustat and alkali metal and the officinal salt that forms with ammonia or organic amine, sodium salt for example, potassium salt, calcium salt, ammonia salt or the like; The solvate that also comprises Febustat and its officinal salt, hydrate for example, alcohol adduct, and the polycrystal of Febustat and its officinal salt, Febustat polycrystal for example, Febustat sodium salt polycrystal, Febustat potassium salt polycrystal or the like.
Pharmaceutical composition of the present invention can be intestinal and parenterai administration form.The intestinal canal administration form comprises: various oral solids and liquid preparation, the parenterai administration form comprises sublingual administration preparation, percutaneous drug administration preparation, injection, membrane or aerosol etc.Preferably active component and any or several pharmaceutically acceptable carrier fully are mixed and made into oral solid preparation.Preferred oral solid formulation is various tablets, granule, drop pill, pill or capsule.
Pharmaceutically suitable carrier is an excipient commonly used in the pharmacy in the pharmaceutical composition of the present invention, comprising: filler, for example, lactose, sucrose, starch, microcrystalline Cellulose, sorbitol or calcium phosphate; Binding agent, for example, syrup, gelatin, hydroxypropyl emthylcellulose, polyvinylpyrrolidone, PEG (Polyethylene Glycol), starch or dextrin; Disintegrating agent, for example, microcrystalline Cellulose, carboxymethyl starch sodium, cross-linking sodium carboxymethyl cellulose or crospolyvinylpyrrolidone; Lubricant, for example, magnesium stearate; The high-molecular bone frame material, for example, hydroxypropyl emthylcellulose, hydroxypropyl cellulose, ethyl cellulose, Brazil wax, hydrogenated vegetable oil or acrylic resin; Filmogen, for example, hydroxypropyl emthylcellulose, polyvinylpyrrolidone or acrylic resin or the like.
Another aspect of the present invention is to disclose the application of described pharmaceutical composition in the medicine of preparation treatment hyperuricemia and relevant various diseases thereof.Described hyperuricemia comprises former and secondary hyperuricemia.The various diseases that described hyperuricemia is relevant comprise the acute and chronic gout that is caused by hyperuricemia, gouty arthritis, gouty nephropathy and renal calculus.
Preferably, become the tablet of unit dose or capsule for oral administration preparation of pharmaceutical compositions of the present invention, every day 1 time, each 1.The dosage of per day for adults is: the Febustat or derivatives thereof for 20-80mg, preferred 20-40mg; Benzbromarone is 20-120mg, preferred 40-80mg.
