Experimental example 1
The experimental example is used for verifying the dissolution performance of the itraconazole pellets of the present invention:
(1) dissolution method
Taking itraconazole pellets prepared in examples 1-10, and filling into capsules, wherein the filling amount of each capsule is 440mg. The dissolution rate of each capsule was measured by a dissolution rate and release rate measurement method (second method of the fourth rule 0931 of the year of the pharmacopoeia 2020), in which 1000ml of a hydrochloric acid solution (9 ml of 37% concentrated hydrochloric acid diluted to 1000ml with water, pH 1.0) was used as a dissolution medium, the rotation speed was 75 revolutions per minute, and 10ml of the solution was taken at 5, 10, 15, 20, 30, 45, 60, 90, 120 minutes, respectively, filtered, and 10ml of the dissolution medium was timely replenished.
(2) Dissolution measurement
Preparing a test solution: the subsequent filtrate was measured precisely at 5ml and placed in a 25ml measuring flask, diluted to scale with methanol-eluting medium (5:95) to give the sample solution.
Preparing a reference substance solution: and (3) taking about 20mg of itraconazole reference substance, precisely weighing, placing into a 200ml measuring flask, adding 40ml of methanol, heating and shaking in a water bath at 40 ℃ to dissolve, cooling, diluting to a scale with a dissolution medium, shaking uniformly, precisely weighing 5ml, placing into a 25ml measuring flask, diluting to the scale with the dissolution medium, shaking uniformly, and taking as a reference substance solution.
And (3) measuring: the cumulative dissolution of each capsule at different times was calculated and a cumulative dissolution curve was drawn by measuring absorbance at a wavelength of 255nm according to ultraviolet-visible spectrophotometry (appendix IVA).
(3) Measurement results
The measurement results are shown in Table 1 and FIG. 1.
TABLE 1 cumulative dissolution rate (%)
| Capsule | 5min | 10min | 15min | 20min | 30min | 45min | 60min | 90min | 120min |

| Example 10 | 2 | 9 | 16 | 23 | 38 | 56 | 70 | 87 | 95 |
As can be seen from table 1 and fig. 1, the in vitro dissolution behavior of itraconazole pellets of examples 1-8 is relatively consistent, demonstrating that the adjustment of the preparation process and the adjustment of the permeation enhancer have no substantial effect on the in vitro dissolution of itraconazole, and therefore the product quality of each formulation is uniform and representative; for examples 9-10, the in vitro dissolution was somewhat slower, but still within the allowable range, because of the relatively large changes in the overall formulation.
Experimental example 2
The itraconazole pellets prepared in example 1, example 4 and comparative example were filled into capsules, and the filling amount of each capsule was 440mg. The 18 healthy male subjects were randomly divided into 3 groups of 6 persons each, each group was administered with one capsule per each period on an empty stomach (0.1 g/person), 240mL of warm water was administered, each subject was blood-drawn before (0 h) and after (0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 24, 48, 72h, respectively, and the itraconazole content in serum was measured by HPLC method, and the bioequivalence of the itraconazole pellets obtained in example 1 and example 4 and the itraconazole pellets obtained in comparative example was calculated, respectively, and the calculation results are shown in tables 2 and 3.
After a single administration, the number of people and symptoms of adverse reactions were counted, and the occurrence rate of adverse reactions was calculated, and the calculation results are shown in table 4.

TABLE 4 adverse reaction statistics table
As can be seen from tables 2 and 3, in the itraconazole pellets prepared in examples 1 and 4, although the content of itraconazole is only 75% of that of the comparative example, the bioavailability of itraconazole in the pellets obtained in examples 1 and 4 in vivo can be maintained at the same level as that of the comparative example due to the use of the permeation enhancer by compounding, i.e., the pellets obtained in examples 1 and 4 significantly reduce the amount of main itraconazole while obtaining the same level of bioavailability as that of the pellets obtained in comparative example, and the reduction of the main drug reduces the occurrence rate of adverse reaction of the drug and the damage degree of adverse reaction to the body.
As can be seen from table 4, in 18 healthy male subjects, no serious adverse reaction occurred after a single administration of itraconazole capsule, but a total of 7 cases of mild adverse reactions occurred. Wherein, the occurrence rate of adverse reaction is obviously reduced in the example 1 compared with the comparative example; compared with the example 1 and the comparative example, the example 4 has obviously reduced occurrence rate of adverse reaction and obviously lighter severity after adverse reaction, which indicates that the application of the rhubarb-aconite root asarum composition can promote drug permeation and has certain harmonizing effect on human body, and can further reduce the occurrence rate or severity of itraconazole adverse reaction.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
