Description
Technical field
The present invention relates to medical technical field, be specifically related to a kind of Febuxostat solid preparation.
Composite highly effective disintegrating agent of the present invention is meant the disintegrating agent compositions of the efficient disintegrating agent composition that adopts two or more.
Efficient disintegrating agent of the present invention includes but not limited to following: hyprolose, polyvinylpolypyrrolidone, cross-linking sodium carboxymethyl cellulose, microcrystalline Cellulose, chitin or preparation technique development from now on produce new efficient disintegrating agent.
Background technology
Febuxostat, chemical name: 2-[3-cyano group-4-(2-methyl propoxyl group) phenyl]-4-methylthiazol-5-carboxylic acid, the clinical gout that is used for the treatment of.Gout (gout) is because the purine substance metabolism disorder, produce uric acid too much and (or) urate excretion reduces, blood uric acid concentration continues to increase the one group of metabolic disease that causes due to the urate crystal deposition soft tissue.Its clinical manifestation mainly is that the arthritis, gouty nephropathy, gout concretion deposition, the uric acid urinary system concretion that show effect repeatedly generate.It is the biochemical basis of gout that uric acid level raises, and asymptomatic hyperuricemia disease is the state in early stage that gout takes place, and gout must be with hyperuricemia.Say that from classification gout is divided former and secondary two big classes, because enzyme defect caused, most reason was not bright, it and Developmental and Metabolic Disorder syndrome are in close relations but it is now know that, and tangible family heritability is arranged except that minority for originator.Secondary cases patient can be caused by multiple reasons such as nephropathy, hematopathy and medicines.
Along with the prolongation of the change of the improving constantly of people's living standard, dietary structure and living habit, average life, human to the understanding of gout and the raising of diagnostic level, the sickness rate of hyperuricemia and gout is ascendant trend year by year, and age of onset presents and becomes younger.Hyperuricemia and gout are owing to uric acid in the body continues to increase the disease that causes above its physiology permissible range even saturated concentration, so Drug therapy strategy that should disease mainly is exactly to reduce the uric acid that raises in blood and the extracellular fluid.Traditional anti-gout drugs-uricosureic agent (as probenecid, benzbromarone etc.) often is attended by side effect such as erythra, heating, kidney damage.Discover with the xanthine oxidase to be that the inhibitor of action target spot has good gout application prospect, xanthine oxidase inhibitor is as anti-gout drugs, it mainly is the allopurinol of the listing sixties in last century, though be leveraged to the present always, it is only applicable to following 3 kinds of patients: the uricosuric medicine can not make that uric acid concentration in its blood is lower than the patient of 70mg/L, the patient that can not tolerate the uricosuric medicine and cause gout simultaneously with the patient of renal dysfunction because uric acid produces to increase.And a lot of side effect are arranged, using the back patient can have heating, allergic rash, stomachache, diarrhoea, leukocyte and thrombocytopenia, even side effect such as liver function injury is arranged.Therefore, the new xanthine oxidase inhibitor of research has crucial meaning.
Febuxostat is a kind of oral xanthine oxidase inhibitor, is the new drug of first treatment hyperuricemia over 40 years, can reduce the uric acid level in the blood, and stops the crystalline deposition of patient with gout joint uric acid.Its IC
50Value has improved 3 orders of magnitude for 1.4nmol/L than allopurinol.The same with allopurinol, the formation of this product uric acid capable of blocking, and uric acid crystal is deposited on gout patient's joint, causes painful swelling.But allopurinol can suppress the enzyme of a series of participation uric acid paths, and this product then only suppresses xanthine oxidase, thereby its effect has more specificity.Doctor MacDonald of TAP company thinks that this difference between the effects makes that in theory Febuxostat is more safer than allopurinol.Allopurinol can cause about 1%～2% patient and side effect occur, and wherein 25% or even fatal.Febuxostat may more be applicable to the renal failure patient, and allopurinol is via renal excretion mainly at liver metabolism.The III clinical trial phase data show of in October, 2004 U.S.'s rheumatology association issue, the curative effect of Febuxostat is better than the golden standard curative allopurinol of present gout.
The Febuxostat tablet is successfully listing abroad, consults domestic and foreign literature, discloses its preparation prescription abroad, has only raw material and pharmaceutic adjuvant in the prescription, and without any the information about recipe quantity; Chinese patent 200610095263.0 discloses the solid preparation of the Febuxostat of different crystal forms, there is not quality standard according to solid preparation, dissolution index particularly, carry out prescription screening, and be that a kind of disintegrating agent of use or a kind of efficient disintegrating agent of " assuming as a matter of course " carries out the preparation of solid preparation, such solid preparation quality can't be qualified.
Summary of the invention
For these reasons, the scientific research personnel of the court is by secular creationary research, according to Febuxostat physics and chemical property, discovery is in preparation Febuxostat solid preparation, Febuxostat concerns with the weight ratio that composite highly effective disintegrating agent, filler have respectively, solid preparation according to the preparation of above-mentioned weight ratio relation has good dissolution, illustrates that Febuxostat solid preparation product quality of the present invention is very outstanding.
Composite highly effective disintegrating agent of the present invention is meant the disintegrating agent compositions of the efficient disintegrating agent composition that adopts two or more.
Lubricant of the present invention and wetting agent are an amount of in formulation preparation, and selected kind includes but not limited to conventional lubricant and the wetting agent that uses of solid preparation
The present invention is achieved through the following technical solutions.
A kind of Febuxostat solid preparation, be prepared from by crude drug Febuxostat and pharmaceutic adjuvant, pharmaceutic adjuvant is composite highly effective disintegrating agent, filler, lubricant and wetting agent, the weight ratio 1 that it is characterized in that Febuxostat and composite highly effective disintegrating agent: 0.1-0.5, the weight ratio of Febuxostat and filler is 1: 0.7-1.2.
