Description

Obeticholic acid pharmaceutical composition, and preparation method and application thereof
Technical Field
The invention belongs to the field of medicines, and particularly relates to an obeticholic acid medicinal composition, and a preparation method and application thereof.
Background
Obeticholic acid (obeticholic acid, 6 alpha-ethyl-3 alpha, 7 alpha-dihydroxy-5 beta-cholane-24-acid, structure shown in formula I) is an oral active analogue of natural human bile acid CDCA (chenodeoxycholic acid), and is clinically used for treating primary biliary cholangitis (PSC).
Figure BDA0002490613810000011
Obeticholic acid has the characteristics of low solubility and high permeability, and the dissolution and dissolution of a drug are rate-limiting steps of in vivo absorption. Therefore, increasing the dissolution rate of the drug is an important means for increasing the bioavailability of the drug. The existing research adopts the modes of reducing the particle size of the raw material medicine, changing the crystal form and the like to improve the dissolution, dissolution and bioavailability of obeticholic acid. However, the electrostatic effect between the drug particles will be increased when the particle size of the drug is too small, which causes the drug particles to agglomerate, thereby affecting the dispersibility of the active ingredients of the drug and the quality of the pharmaceutical preparation. Moreover, the percentage of pharmaceutically acceptable carriers (pharmaceutical excipients) in the pharmaceutical preparation reaches 95%, and the percentage and content of obeticholic acid are low, so that effective measures need to be taken to solve the problems of dispersibility of pharmaceutical particles in the preparation and uniform mixing between obeticholic acid and the pharmaceutically acceptable carriers, and further solve the problems of quality uniformity, drug dissolution, bioavailability, effectiveness, safety and the like of the pharmaceutical preparation, and the pharmaceutical preparation becomes a research hotspot in the field.
CN107531742A adopts a dry granulation method to prepare obeticholic acid tablets, and the method comprises the steps of screening, pre-blending, dry granulation, total mixing, compression, coating, packaging and the like, wherein the pre-blending comprises the following steps:
(1) weighing the drug obeticholic acid according to the prescription design, premixing the drug obeticholic acid and part of microcrystalline cellulose by using a mixer, and discharging to obtain a drug/microcrystalline cellulose premix;
(2) adding part of microcrystalline cellulose into the mixer in the step (1), mixing, cleaning residual drug obeticholic acid on the inner wall of the mixer to obtain a microcrystalline cellulose cleaning substance, and discharging;
(3) passing the drug/microcrystalline cellulose premix prepared in the step (1) and the microcrystalline cellulose cleaning substance prepared in the step (2) through a 1.0mm screen for later use;
(4) dividing the rest microcrystalline cellulose in the internal granulating material into 1/4 parts (by mass, the same below), 1/4 parts and 1/2 parts for later use;
1/4 microcrystalline cellulose, 1/2 medicament/microcrystalline cellulose premix in step (1), "microcrystalline cellulose cleaning product in step (2)," 1/2 medicament/microcrystalline cellulose premix in step (1) "and 1/4 microcrystalline cellulose are added into another mixer with larger volume in sequence for mixing;
(5) then adding sodium carboxymethyl starch and the rest 1/2 microcrystalline cellulose for mixing;
(6) sieving magnesium stearate with 0.5mm mesh sieve, adding into above materials, and mixing.
The preparation process of the method is very complex, the microcrystalline cellulose (MCC), the carboxymethyl starch sodium (CMS-Na) and the magnesium stearate which are used for premixing are required to be respectively screened in advance, and the microcrystalline cellulose is required to be mixed with obeticholic acid and other pharmaceutically acceptable carriers in batches for multiple times in the premixing step according to a specific sequence, so that the defects of complicated operation steps, complex working procedures, poor process stability, low production efficiency, high manufacturing cost, inconvenience for large-scale industrial production and the like exist.
CN109620812A adopts a wet granulation pot to premix obeticholic acid or pharmaceutically acceptable salts, esters or amino acid conjugates thereof and pharmaceutic adjuvants to prepare a premix thereof, and then dry granulation is carried out to prepare the required preparation. The method has the defects of unstable preparation process, low production efficiency, high preparation cost, no contribution to large-scale industrial production and the like.
Therefore, the preparation method of obeticholic acid preparation, which is simple and convenient to operate, good in process stability, more excellent in cost and suitable for large-scale industrial production, is urgently needed to be developed, and the problems of quality uniformity, preparation dissolution rate and the like of obeticholic acid preparation are effectively solved.
