Abstract
The invention discloses a Febuxostat tablet and a preparation method thereof. The Febuxostat tablet comprises a tablet core and a coating. The tablet core comprises the following components in weight percentage: 5-30 percent of Febuxostat, 15-60 percent of filler, 1-20 percent of disintegrating agent, 0.1-5 percent of surface active agent, 0.1-8 percent of lubricant and a right amount of adhesive. According to the Febuxostat tablet, trough adopting the powerful disintegrating agent within a reasonable proportional region, and meanwhile, through jointly using the surface active agent, the poorly water-soluble drug Febuxostat dissolves out, and further, the dissolvability of the Febuxostat is increased, and the bioavailability of the Febuxostat is improved. Moreover, the Febuxostat tablet is simple in preparation method, controllable in quality and high in stability.
Description
Technical field
The present invention relates to field of medicaments, particularly relate to a kind of Febustat tablet.
Background technology
Gout be that uric acid body accumulation, causes urate crystal in joint and each internal organs deposition owing to producing uric acid in body too much and kidney removing ability declines.Uric acid does not have any physiological function in human body, under normal circumstances, the uric acid producing in body, 2/3 is discharged by kidney, and 1/3 of remainder is discharged from intestinal.In body, uric acid constantly generates and drains, so it maintains certain concentration in blood.Contained uric acid in every liter of blood of normal person, male is below 0.42mmol, women is no more than 0.357mmol.In the composition and decomposition process of purine, there is the participation of plurality of enzymes, due to the birth defect of enzyme or the factor that some is not yet clear and definite, metabolism gets muddled, and makes the synthetic increase of uric acid or discharges and reduce, and result all can cause hyperuricemia.> 0.44mmol/L when hyperuricemia excessive concentration), uric acid is deposited in joint, soft tissue, cartilage and kidney with the form of sodium salt, causes the foreign body inflammatory reaction of tissue, has become to cause the seed of trouble of gout.
Along with the improving constantly of people's living standard, dietary structure and the change of living habit (food that is rich in nucleoprotein increases), the prolongation of average life, the raising of the mankind to the understanding of gout and diagnostic level, no matter Shi American-European countries is still in countries in Asia, the prevalence of gout has the trend increasing year by year, and the prevalence of China's hyperuricemia and gout is ascendant trend linearly especially.The prevalence of American-European hyperuricemia is up to 2%～18%; The prevalence of the 30 years old above adult's hyperuricemia in China Taiwan is 17.3%.There is the too high situation of blood uric acid in 20 years old above crowd approximately 2.4%～5.7% of China; There were significant differences for the prevalence of age groups hyperuricemia, and old people's prevalence of hyperuricemia can be up to more than 24%; The total prevalence of all age bracket gouts is about 0.84%.
The means of at present treatment of gout being taked are conventionally promote urate excretion and suppress uricopoiesis, and adopt adequate measure to improve related symptoms.The generation of uric acid is relevant with purine metabolism in body, purine metabolism process finally, hypoxanthine generates xanthine under the effect of xanthine oxidoreductase enzyme (XOR), more further generates uric acid.The activity that suppresses this enzyme can effectively reduce the generation of uric acid.Allopurinol has inhibitory action to XOR, is unique for suppressing the medicine of uricopoiesis clinically over 30 years, is the first-line treatment medicine of current gout.
Allopurinol is used for the treatment of chronic gout, be applicable to uricopoiesis too much, irritated to uricosuric, and the patient who is not suitable for using uricosuric, especially gouty nephropathy or uric acid renal calculus person are had to good effect, being the medicine that the level that onlyly before this can effectively reduce uricopoiesis, reduce blood and urine uric acid is treated primary gout, is the gold medicine for the treatment of gout.But because allopurinol has certain infringement to liver, therefore liverish gout patients generally should not be used this medicine.In addition, allopurinol can cause bone marrow infringement and produce leukopenia a few patients.Therefore the untoward reaction of allopurinol is more.
Febustat is a novel xanthine oxidase (XO) inhibitor over nearly 40 years, it is the XO inhibitor of first non-purine type, inhibitory action to XO enzyme has high selectivity, can to the XO of oxidized form and reduced form, produce remarkable inhibitory action simultaneously.Febustat is compared with current gout gold medicine allopurinol, has stronger pharmacologically active, and higher effect selectivity shows better curative effect and good safety in clinical.Therefore, Febustat is a kind of newtype drug that more can safe and effective treatment hyperuricemia, extremely has clinical meaning.
But because the dissolubility of Febustat itself is less, there is the problems such as the poor and bioavailability of dissolution is not high in the common oral solid formulation that contains this active component, medicinal effects in Febustat in a lot of situations does not reach desirable requirement, this has just caused the medicinal content of Febustat higher, and the undesirable problem of effect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of prescription composition is few, adjuvant is simple and easy to get, stripping is complete, stay-in-grade Febustat tablet.
For this reason, a kind of Febustat tablet is provided in the present invention, this Febustat tablet comprises label and coating, and label comprises following component according to weight percentage: Febustat 5%-30%, filler 15%-60%, disintegrating agent 1%-20%, surfactant 0.1%-5%, lubricant 0.1%-8%, binding agent are appropriate.Febustat tablet prepared by the present invention, according to the performance of Febustat medicine, by reasonably adopting potent disintegrating agent in proportion, combine simultaneously and use surfactant and other adjuvant to make the stripping of insoluble drug Febustat, and then the dissolubility of increase Febustat, improve its bioavailability.
Those skilled in the art are reading on basis of the present invention, can access the suitable amounts of binding agent according to rational analysis, do not repeat them here.
