Problems solved by technology

For example, the process of intravenous emulsion injection is unstable, and the temperature, emulsification time and production equipment all have an impact on product quality, resulting in uneven emulsion particles; oil and water stratification, cracking, phase inversion, flocculation and Corrosion and other phenomena make it unusable; storage conditions need to be protected from light, and the temperature should be kept within the range of 6±2°C; the service life is only 1 year, and the actual use is greatly affected by the environment, and the product often fails or loses its shape within the validity period Unqualified; in clinical use, side effects such as phlebitis, vascular sclerosis, hemangioma, muscle and blood vessel irritation, allergic reaction, etc., are poorly tolerated by patients
Brucea javanica oil oral emulsion is a thermodynamically unstable system. The physical stability of the oral emulsion after sterilization is poor. Its active ingredie

Embodiment 1-3

[0037] Example 1-3 Preparation of Brucea javanica oil enteric-coated soft capsules

[0038] Example 1-3 Brucea javanica oil enteric-coated soft capsule composition and index inspection results, see Table 1-2.

[0039] The preparation method is:

[0040] 1) Extraction of Brucea javanica oil: Crude Brucea javanica medicinal materials are pulverized into coarse powder, weighed 5kg, placed in an extraction tank, added 6 times the amount of solvent gasoline, refluxed for 1 hour, filtered, and the residue is added 6 times of solvent gasoline, and refluxed for extraction After 1 hour, filter, combine the filtrate, and recover the solvent under reduced pressure until it is exhausted. The extraction rate is between 12.8% and 13.4%. The results are shown in Table 1.

[0041] 2) Preparation of Brucea javanica oil soft capsule: Take 5000ml of Brucea javanica oil, put it in a stainless steel bucket, add 750g of soy phospholipid, stir to dissolve all, and filter to prepare sac fluid. Take the c...

Description

Technical field [0001] The invention relates to a pharmaceutical enteric soft capsule preparation, in particular to an enteric soft capsule preparation containing brucea javanica oil, and a preparation method and application thereof. Background technique [0002] Malignant tumor is one of the malignant diseases with the highest morbidity and mortality in the world today. According to statistics from the World Health Organization, there are currently 8.7 million new cancer patients worldwide each year, with 6-7 million deaths, accounting for one-tenth of the total number of deaths in the population, and an annual growth rate of 2-3%. In my country, 2 million new malignant tumor patients are added every year, and more than 1.3 million people die. [0003] In recent years, due to changes in the climate and diet, the incidence of lung cancer, liver cancer, gastric cancer, colon cancer and pancreatic cancer and other malignant solid tumors has shown a rapid increase. Combination of Ch...
