Problems solved by technology

We believe that the disadvantage of this patent is that in the production process, rhubarb and Glauber's salt are added to the substrate at a temperature of 60-90°C and stirred, and the control of cooling time is lacking in the production. The effect of sennoglycogen A decreases with the increase of temperature and the extension of time, and there is a problem that the activity of the drug decreases; secondly, rhubarb and mirabilite are cold drugs, "repelling down to attack fire" and "attacking dryness in the intestines". "It is often used for constipation in adults, but it is not suitable for patients after surgery or children, etc.
[0004] When docusate sodium is mixed with a water-soluble base or a fat-soluble base or both bases to prepare suppositories, there is a problem of uneven drug solution. After mixing, the product has precipitation and color difference, which affects the drug content uniformity and appearance of the suppository after pouring. Conducive to drug production control and product application

Embodiment 1

[0012]

[0013] Operation: semi-synthetic fatty acid glycerides plus docusate sodium are completely melted when heated to 50°C, hydrogenated palm kernel oil is continuously stirred, and the matrix is ​​completely melted with residual heat, stirred evenly, and poured when the mixture is cooled to 40°C. The mold can be cooled at 0-4°C for 2-3 minutes in advance. After pouring for 5 minutes, scrape it flat, and release the mold after 10 minutes. The temperature during injection molding can be controlled at about 40°C.

Embodiment 2

[0015]

[0016] Operation: Heat hydrogenated palm kernel oil and polyethylene glycol at 20000°C, start to melt at 38°C, and completely melt at 48°C, add docusate sodium and magnesium oxide and stir evenly, cool the mixture to about 38°C (that is, before solidification) and pour. Pouring, cooling, leveling, and mold removal.
