Description
Technical Field
The invention belongs to the field of pharmaceutical preparations, and in particular relates to an abiraterone acetate soft capsule and a preparation method thereof.
Background
Abiraterone acetate (Abiraterone Acetate) is a white to off-white, non-hygroscopic crystalline powder. Abiraterone acetate is an Abiraterone prodrug, a selective irreversible inhibitor of 17 alpha-hydroxylase/C17, 20-lyase (CYP 17). The enzyme is expressed in testis and adrenal tissue and catalyzes the conversion of pregnenolone and progesterone to testosterone precursors, DHEA and androstenedione, respectively, by 17 alpha hydroxylation and cleavage of the C17,20 bond. Abiraterone can inhibit the activity of CYP17 and thereby prevent testosterone synthesis in the testes, adrenal glands and tumors. Prostate cancer is an androgen dependent disease and testosterone inhibition is a key pharmacological tool in controlling the progression of prostate cancer. The chemical structure of abiraterone acetate is shown in the following formula 1:
Abiraterone acetate is taken as a lipophilic compound, the octanol-water partition coefficient is 5.12 (LogP), the pKa of aromatic nitrogen is 5.19, the Abiraterone acetate is almost insoluble in water (0.01 mg/ml), the osmotic pressure difference is BCS four drugs, and the bioavailability is extremely low when the Abiraterone acetate is orally taken.
The crude drug Zytiga abiraterone acetate tablet (250 mg gauge) was developed by Janssen-Cilag International n.v. belgium, inactive ingredients include: colloidal titanium dioxide, croscarmellose sodium, lactose monohydrate, magnesium stearate, microcrystalline cellulose, povidone, and sodium lauryl sulfate. Is approved in the united states for use with prednisone to treat metastatic castration-resistant prostate cancer (mCRPC). The original grinding medicine Zytiga has very low oral bioavailability (less than 10%), the daily administration dosage is up to 1000mg, but only less than 10% of the medicine can exert the medicine effect.
Prescription information for the original drug Zytiga indicates that the drug must be taken on an empty stomach and that no food should be taken for at least 2 hours before and at least 1 hour after the drug, indicating that food has a great effect on abiraterone acetate absorption, and that commercial formulations require only a specific period of time before meals. The Zytiga specification emphasizes that abiraterone acetate increases systemic exposure when administered with food. Specifically, abiraterone acetate Cmax and AUC 0-∞ increased by about 7-fold and 5-fold, respectively, when administered with a low fat diet (7% fat, 300 calories); abiraterone acetate Cmax and AUC 0-∞ increased by about 17-fold and 10-fold, respectively, when given with a high fat diet (57% fat, 825 calories). Although abiraterone acetate has good effect of treating advanced prostate cancer by oral administration, the characteristic of low solubility and osmotic pressure difference brings serious trouble to formulation development.
Patent CN106687112a provides an improved abiraterone acetate preparation, by controlling the particle size of abiraterone acetate as a raw material, the bioequivalence and bioavailability of a unit dosage form of abiraterone are improved by 1 time in healthy male subjects in a fasting state, wherein the unit dosage form of 500mg dose and 1000mg dose Zytiga. Although the dosage of the preparation is reduced by 500mg, only abiraterone acetate is crushed, the particle size is controlled in a smaller range, so that dissolution and absorption are facilitated, the permeability of the abiraterone acetate to gastrointestinal epithelial cells cannot be increased, the oral bioavailability is still low, the specific surface area of the abiraterone acetate is overlarge after crushing, and the risk of oxidation of the abiraterone acetate is increased.
Patent CN102961358B relates to an abiraterone acetate liquid capsule, comprising a capsule shell and contents, characterized in that: the content consists of abiraterone acetate, a solvent, single fatty acid glyceride and an antioxidant: the solvent is selected from: diglycerides, triglycerides, 1, 2-propanediol, and mixtures thereof. However, the propylene glycol contained in the liquid capsule can volatilize from the content during the storage process, so that the propylene glycol content in the content can be seriously reduced, and Abiraterone is separated out, which may cause serious quality problems.
Patent document CN107278152a relates to an abiraterone acetate complex, a process for its preparation and pharmaceutical compositions containing them, comprising 5-40 wt.% abiraterone acetate, 5-80 wt.% polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer, 0.1-50 wt.% sodium deoxycholate. The compound can reduce the food effect and give up the requirement of taking medicine on an empty stomach, and can improve the oral bioavailability by 5 times at most, but the preparation process of the compound preparation is complex.
The invention relates to the technical field of pharmaceutical preparations, in particular to a pharmaceutical composition containing abiraterone acetate, and a preparation method and application thereof. The pharmaceutical composition comprises: active ingredients: abiraterone acetate; auxiliary materials: at least one oil phase, at least one emulsifier, and at least one emulsifier. The pharmaceutical composition provided by the invention spontaneously disperses under gastrointestinal peristalsis to form O/W type nanoemulsion after being orally taken. The formed nanoemulsion has small particle size, increases the penetrability of intestinal epithelial cells, and can remarkably improve the bioavailability of the medicament. Compared with microemulsion, the self-emulsifying solution has higher stability and can meet the requirement of long-term storage. The medicine composition of the invention has stable content. Compared with the original grinding medicine Zytiga, the difference between before meal and after meal is obviously reduced; the pharmaceutical composition can be further prepared into capsules, and the capsules are stable in property. However, the co-emulsifier ethanol, propylene glycol, etc. used in this patent can be exerted from the contents during storage, so that the ethanol or propylene glycol content in the contents can be severely reduced, which may cause precipitation of abiraterone during long-term storage.
In summary, abiraterone acetate has the characteristics of low solubility and osmotic pressure difference, and the problem of poor oral bioavailability cannot be solved obviously by crushing abiraterone acetate and controlling the particle size in a smaller range, so that the oral bioavailability of abiraterone acetate can be improved obviously in theory, and the influence of food is eliminated, but the content in the liquid capsule is easy to volatilize to form propylene glycol or ethanol, and the abiraterone can be separated out in the long-term storage process.

Determination of solvent
The Abiraterone soft capsule preparation consists of the content of Abiraterone soft capsule and soft capsule shell, and needs to study the content prescription at the same time, and firstly, the solvent of the self-grinding preparation is determined. The experiment researches the dissolution condition of the bulk drug in various solvents in the content of the Abiraterone soft capsule. In this test, 10g of purified water, ethanol, castor oil (castor oil), capmul MCM (caprylic/capric acid mono-diglyceride), hydrogenated castor oil and medium chain triglyceride were taken, respectively, and the dissolution of abiraterone Acetate (API) in these solvents was studied, and is shown in Table 1.
TABLE 1 dissolution of Abiraterone acetate
As can be seen from Table 1, ① Abiraterone acetate has higher solubility in ethanol, castor oil, caprylic/capric acid mono/diglyceride, but when ethanol is used as a solvent, a large amount of crystals are precipitated after being left at room temperature for 24 hours; only 3% was dissolved in medium chain triglycerides (25 ℃), hardly in hydrogenated castor oil and purified water. ② Generally speaking, the self-microemulsifying drug delivery system is finally prepared into soft capsules or hard capsules, if ethanol and other volatile components are contained, the substances possibly penetrate through capsule shells to reduce the solubility of the drug, so that the lipophilic drug is precipitated, i.e. if the self-developing agent adopts ethanol as a solvent, the ethanol is easy to exude from the capsule shells and volatilize, and the proportion of the ethanol in the content can be seriously reduced in the preparation and storage processes, so that the crystallization of the drug can be caused; ③ Compared with the dissolution of abiraterone acetate in castor oil and caprylic/capric acid mono-diglyceride, the abiraterone acetate is found to be more soluble in the caprylic/capric acid mono-diglyceride, and the caprylic/capric acid mono-diglyceride has a certain emulsification effect, so that the self-grinding preparation can be spontaneously dispersed to form O/W type emulsion drops under gastrointestinal peristalsis. Therefore, the preparation adopts caprylic capric acid mono-diglyceride as the solvent of the self-grinding preparation.
Determination of surfactant
In order to ensure that the self-developed agent spontaneously disperses under the gastrointestinal motility to form O/W emulsion drops after being orally taken, the surfactant is mostly a nonionic surfactant with higher hydrophilic-lipophilic balance (HLB) value (generally 9-20), has low toxicity, is relatively stable in solution, is not influenced by strong dielectrics, inorganic salts, acid and alkali, has good compatibility with other types of surfactants, has small hemolysis, can be compatible with most medicaments, and can cause reversible transformation of permeability of gastrointestinal walls. At the same time, the surfactant is selected to take into account the match with the oil phase. This test selects surfactants such as polyoxyethylated castor oil (EL-40), span 80, tween 80 and polyethylene glycol-15 hydroxystearate (Solutol), and organically combines two or three of these surfactants, unexpectedly found that when polyoxyethylated castor oil: tween 80: span 80=1:1:0.25 and tween 80: at span 80=1:1.25, the emulsification effect is best, and the emulsion drops with blue opalescence are formed by slight oscillation and can exist stably. Details are shown in Table 2.
TABLE 2 selection of surfactants
The composition of the 2 surfactants is adopted to prepare soft capsules, and the influence of the soft capsules on the quality of products is examined.
TABLE 3 influence of surfactants on product quality (40 ℃ C.+ -. 2 ℃ C./75% RH.+ -. 5% RH)
As can be seen from table 3, the different surfactant compositions, for different product quality, when tween 80: span 80=1:1.25, its product quality meets the requirements, and at 3 months of acceleration, its total impurities are significantly lower than prescription 2.
In summary, the surfactant composition of the self-grinding preparation is span 80 and tween 80, and the dosage of each surfactant is further optimized on the basis, and the specific details are shown in examples 1-4.

The testing method comprises the following steps: abiraterone acetate soft capsules (prepared in examples 1 and 2) and the original grinding Zytiga tablets were tested for dissolution rate under conditions of 37 ℃ and 900ml of SDS medium of pH4.5-0.25% at 50 rpm according to the second method of the four-part general rule 0931 of the 2015 edition of Chinese pharmacopoeia.
Wherein, the pH is 4.5-0.25% SDS medium: weighing 6.78g of anhydrous sodium dihydrogen phosphate, adding 1000ml of water for dissolution, adjusting the pH value to 4.5 by using 5mol/L sodium hydroxide solution to obtain a buffer solution, weighing 2.5g of sodium dodecyl sulfate, adding the buffer solution, and dissolving to obtain the finished product.
The specific method is as follows:
TABLE 1-1 dissolution of Abiraterone acetate soft capsules and Zytiga tablets (%)
| Sampling point/min | Zytiga | Example 1 | Example 2 | Example 3 | Example 4 | Comparative example 1 |
| 5 | 13.77 | 69.01 | 68.61 | 71.51 | 72.01 | 73 |
| 10 | 28.03 | 93.51 | 92.01 | 93.15 | 94.51 | 93 |
| 15 | 41.78 | 95.83 | 94.91 | 96.41 | 96.83 | 96 |
| 20 | 57.99 | 97.62 | 96.72 | 97.52 | 98.05 | 98 |
| 30 | 79.15 | 98.70 | 99.10 | 99.60 | 98.20 | 99 |
| 45 | 92.88 | 98.52 | 99.52 | 98.41 | 99.12 | 98 |
The comparison results in Table 1-1 show that: ① The abiraterone acetate soft capsules (examples 1,2, 3 and 4) are basically completely dissolved in a medium for 15min (the dissolution standard of the original grinding drug Zytiga is that 45min is not less than 85.0% of the marked amount), and the dissolution of the abiraterone acetate tablets Zytiga on the market still cannot reach 85.0% in 30 min; ② The dissolution rate of the abiraterone acetate soft capsules (examples 1,2, 3 and 4) of the invention is not significantly different from that of comparative example 1. Therefore, the abiraterone acetate capsule can effectively improve the dissolution rate of abiraterone, and remarkably improve the oral bioavailability of abiraterone acetate.

The test examples provide stability (long-term test and acceleration test) tests of the abiraterone acetate soft capsules provided in examples 1-4, and the detection results are shown in tables 2-1 and 2-2.
TABLE 2-1 stability of samples in long term test (25 ℃ C.+ -. 2 ℃ C./60% RH.+ -. 5% RH)
Note that: "-" represents: the solution is clarified, and the medicine is not precipitated;
"+" represents: the clear solution and the medicine are separated out in small quantity.
TABLE 2 stability of samples under accelerated test (40 ℃ C.+ -. 2 ℃ C./75% RH.+ -. 5% RH)
Note that: "ND" represents undetected; "NA" represents undetected.
The comparison results in Table 2-1 show that: the abiraterone acetate soft capsules (examples 1,2, 3 and 4) of the invention have no significant change in content properties within 9 months of a long term, and comparative example 1 has no significant difference within 6 months of a long term, but a small amount of medicine is precipitated within 9 months of a long term, which is caused by the following reasons: the formulation of the contents of comparative example 1 contained propylene glycol and ethanol, which may penetrate the capsule shell and volatilize with the lapse of storage time, decreasing the solubility of the drug, resulting in precipitation of abiraterone acetate.
The comparison results in Table 2-2 show that: ① The abiraterone acetate soft capsules (examples 1,2, 3 and 4) have a general impurity increasing trend within 6 months of acceleration, and meet the product quality requirement (the general impurity in the quality standard of original grinding medicine Zytiga is not more than 2.0 percent); ② The Abiraterone acetate soft capsules (examples 1,2, 3 and 4) of the invention have obviously smaller total impurity increase amplitude than that of comparative example 1 within 6 months of acceleration

TABLE 3-1 self-emulsifying ability of samples and stability results
Example 8
This test example provides a pharmacokinetic test of example 1 and abirater acetate Long Yuan, ground drug Zytiga.
And (3) test design: because of large in vivo variability of the original grinding medicine Zytiga (abiraterone acetate tablets), the pharmacokinetic study adopts a three-period crossover test of 6 dogs, a soft capsule of abiraterone acetate (specification: 40 mg) and 2 original grinding medicines Zytiga (specification: 250mg, 2 tablets each time) are orally taken on an empty stomach, blood samples are collected, the concentration of abiraterone in blood plasma is measured, and main pharmacokinetic parameters are calculated. Details are shown in Table 4-1.
Test object: healthy beagle dogs were randomly divided into 3 groups of 2, 3 cycle crossover tests were performed. During the test, the water is freely drunk, the administration is fasted for more than 12 hours before each period of administration, and the preparation is taken with 20ml of water when the administration is carried out, and the administration is carried out after 6 hours. The period of the week washing was 7 days.
Table 4-1 comparative pharmacokinetic study group design
Note that: t: abiraterone acetate soft capsules are administered to 1 granule/dog, namely 40 mg/dog;
R: abiraterone acetate tablet is administered to 2 animals/dog, i.e. 500 mg/dog.
Table 4-2 original grinding drug Zytiga mg contrast Abituron acetate soft capsule 40mg pharmacokinetic parameters (empty stomach test)
Note that: tmax is the peak time, cmax is the maximum blood concentration (peak concentration), AUClast is the AUC (time-to-drug curve area) of the duration from the start of administration to the last point;
As can be seen from Table 4-2, the oral bioavailability (AUClast) of 1 Abiraterone acetate soft capsule (40 mg) administered orally on an empty stomach of beagle dog was 101.9% and 95.3% respectively compared with the original grinding drug Zytiga (R1 st) and the original grinding drug Zytiga (R2 nd). Compared with the original grinding medicine Zytiga (specification 250 mg), the abiraterone acetate soft capsule has the advantages that the oral bioavailability is improved to 12.5 times, and the variability of AUClast is smaller.
As can be seen from fig. 1, 2 and 3, the abiraterone acetate soft capsule has close curves when different individuals are in abiraterone, while the original grinding medicine Zytiga has more discrete curves when different individuals are in abiraterone. The reason for this may be that the soft capsule dosage form does not need to undergo the dissolution step of the original drug Zytiga on the digestive tract, but the step directly affects the absorption of the drug, thereby improving the bioavailability and reducing the individual difference.
In summary, after ① dogs have orally taken abiraterone acetate soft capsules on an empty stomach, the dissolution step of the original grinding medicine Zytiga is skipped on the alimentary canal, the oral bioavailability (AUClast) of the abiraterone acetate soft capsules is 12.5 times of that of the original grinding medicine Zytiga, and the abiraterone acetate soft capsules can obtain more consistent T max、Cmax and AUC among individuals, thereby being beneficial to the implementation of clinical treatment and the control of safety risks.

This test example provides an absorption influence test of food on example 1.
And (3) test design: 8 dogs were subjected to double-cycle crossover test, respectively, orally taken abiraterone acetate soft capsules on an empty stomach and after meal, blood samples were collected, the concentration of abiraterone in plasma was measured, and main pharmacokinetic parameters were calculated. Details are shown in Table 5-1.
Test object: healthy beagle dogs were randomly divided into 2 groups of 4, and 3 cycle crossover experiments were performed. Free drinking water during the test. Fasting administration is carried out for more than 12 hours before administration, and the preparation is taken with 20ml of water when administration is carried out, and is fed after administration for 6 hours; the stomach tube is fed quantitatively 30 minutes before the administration after meal administration. The period of the week washing was 7 days.

Note that: t: abiraterone acetate soft capsules are administered to 1 granule/dog, i.e. 40 mg/dog.
TABLE 5-2 pharmacokinetic parameters of Abiraterone in plasma after oral Abiraterone acetate Soft Capsule on empty stomach in dogs
TABLE 5-3 pharmacokinetic parameters of Abiraterone in plasma after oral Abiraterone acetate Soft Capsule after Canine postprandial
* The relative bioavailability f= (abiraterone acetate soft capsule postprandial AUC 0-t/fasting AUC 0-t) of each individual is 100%
As is clear from tables 5-2 and 5-3, the relative bioavailability of the oral abiraterone acetate soft capsule after 30 minutes after a meal of dogs is 79.19% (44.45% -106.80%) compared with the oral abiraterone acetate soft capsule. The paired t-test results after natural logarithmic transformation of the principal pharmacokinetic parameters are shown in tables 5-4.
Table 5-4 main pharmacokinetic parameters of abiraterone in plasma after oral administration of abiraterone acetate soft capsule on empty stomach or after meal paired t-test results
As can be seen from tables 5-4, the difference in Cmax was significant (P < 0.01) after oral administration of the soft capsule after dogs' meal, compared with the empty oral abiraterone acetate soft capsule, whereas the difference between AUC0-t and AUCinf was not statistically significant.
The literature reports that the exposure of the original grinding drug Zytiga high-fat postprandial abiraterone can reach 10 times of the fasting exposure. In the test, after oral abiraterone acetate soft capsules are taken on a canine empty stomach or after a meal, the exposure of abiraterone acetate is not increased, and the reason is probably that the abiraterone acetate soft capsules do not need to go through the dissolution step of the original grinding medicine Zytiga on the alimentary canal, and the higher exposure can be achieved without the help of fat in food to realize the dissolution of the medicine, and the absorption degree of the abiraterone acetate soft capsules can not be increased any more due to the existence of food. The relative bioavailability of the postprandial abiraterone is slightly lower than that of the fasting, probably because food promotes peristaltic emptying of the digestive tract, so that the residence time of the drug in the main absorption site is shortened.
In conclusion, compared with the empty stomach, the exposure of the Abiraterone is slightly reduced after the oral self-development agent is taken after dogs are taken after meals, and the phenomenon that the exposure of the Abiraterone is obviously increased when the original development agent Zytiga is taken after meals is avoided. Thus, abiraterone acetate soft capsules can reduce dietary-related safety risks associated with abiraterone exposure.
