Abstract
The application relates to the technical field of medicine preparation, in particular to a preparation method of riocigua tablets. The preparation method comprises the following specific steps: s1, micronizing main medicines into different particle sizes and uniformly mixing for later use; s2, uniformly mixing the micronized main medicine, the filler, the disintegrating agent and the adhesive, and granulating by a wet method by using a solubilizer to prepare a soft material; s3, passing the soft material through a screen to obtain wet granules, drying the wet granules in a boiling drying granulator, and sieving the dry granules to obtain dry granules; s4, adding a lubricant into the dry particles and uniformly mixing to obtain total mixed particles; s5, putting the total mixed particles into a tablet press for tabletting to obtain tablet cores; s6, coating the tablet core with coating powder to obtain film coated tablets, and preparing Li Aoxi Gua tablets. The prepared sample and the reference preparation have similar dissolution curves in phosphate buffer medium with pH of 6.8, have similar speed, and are favorable for quality control of medicines and have better reproducibility.
Description
Technical Field
The application relates to the technical field of medicine preparation, in particular to a preparation method of riocigua tablets.
Background
The medicine for treating pulmonary arterial hypertension mainly comprises: prostacyclin-based drugs, endothelin receptor antagonists, calcium channel blockers, phosphodiesterase-5 inhibitors, anticoagulants, diuretics, others, and the like.
Riocidine (Adempas) was the first new class of Soluble Guanylate Cyclase (SGC) agonists developed and marketed by Bayer corporation, the first drug approved worldwide for the treatment of chronic thromboembolic pulmonary hypertension (CTEPH), and the only drug currently available is Pulmonary Arterial Hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH).
Riocidine has chemical name of 4, 6-diamino-2- [1- (2-fluorobenzyl) -1H-pyrazole [3,4-b ]]Pyridin-3-yl]-methyl 5-pyrimidine (methyl) carbamate of formula C 20 H 19 FN 8 O 2 The molecular weight is 422.42, the CAS number is 625115-55-1, and the structural formula is as follows:
riocidine serves as a novel Soluble Guanylate Cyclase (SGC) agonist, has a dual action mode, can increase sensitivity of the Soluble Guanylate Cyclase (SGC) to endogenous Nitric Oxide (NO) on one hand, and can directly stimulate the SGC independently of NO on the other hand, so that the yield of Cyclic Guanylate (CGMP) is increased.
The Chinese patent literature publication No. CN105596311A, the patent name is "Riocidine oral solid preparation method", discloses a preparation method of Riocidine tablet: the main medicine and the filler are mixed and ground, so that the main solubility is improved. The main medicine in the grinding process may have adsorption phenomenon, the specification of the product is lower, the adsorption of the main medicine easily causes the condition of lower sample content, mannitol is added in the prescription, and the addition of the material can change the permeability of the active ingredients of the medicine, thereby affecting the medication safety of patients.
The Chinese patent literature publication No. CN104434845A, the patent name is "solid pharmaceutical preparation containing riocigua", discloses a preparation method of riocigua tablets: 1) Weighing prescribed amount of water-soluble polymer, and heating and melting the water-soluble polymer at 65 ℃ to obtain a molten liquid; 2) Slowly stirring the melt obtained in the step 1), slowly adding the prescription amount of riocigua, and after the riocigua is completely added, vigorously stirring the melt for 30 minutes to uniformly disperse the medicine; 3) Rapidly cooling the melt obtained in the step 2) at the temperature of minus 20 ℃ and solidifying for 2 to 3 hours to obtain a solidified substance; 4) Crushing the solidified material obtained in the step 3) at 4-8 ℃, sieving with a 80-mesh sieve, drying under reduced pressure for 4 hours to obtain a solid dispersion, 5) uniformly mixing the solid dispersion obtained in the step 4 with a prescribed amount of diluent and disintegrating agent, compressing the mixture by using a dry granulator, and performing primary granulation; 6) Sieving the granules obtained in the step 5) with a 20-mesh sieve; 7) Tabletting the materials obtained by blending the lubricant and the materials obtained in the step 6) by using a high-speed tabletting machine to obtain tablet cores; 8) And (3) coating the tablet core obtained in the step 7) to obtain the film-coated tablet. The preparation method is difficult to realize in the actual production process, and has the advantages of high labor and time consumption and high preparation cost.
The Chinese patent literature of the application discloses a preparation process of the riocigua tablet with the publication number of CN106913554A and the patent name of the riocigua tablet is a preparation method of a preparation for treating pulmonary arterial hypertension: pretreating raw materials, and micronizing riocido to the required granularity; preparing a liquid medicine, namely dispersing the micronized riociquone into an aqueous solution of an adhesive and a solubilizer; and granulating, namely adding granulating auxiliary materials into a fluidized bed, spraying the liquid medicine into the fluidized bed, and granulating by the fluidized bed in one step. The preparation method disperses the micronized raw material medicine into the adhesive, which can cause precipitation phenomenon and has poor process reproducibility.
Disclosure of Invention
The application aims at solving at least one of the technical problems existing in the prior art, and therefore, one aspect of the application aims at providing a preparation method of riocidine tablets, which comprises the following specific steps:
