Abstract

The invention discloses curcumenol solid dispersion and an oral solid preparation thereof. The solid dispersion is composed of curcumenol and a carrier material, wherein a weight ratio of the curcumenol to the carrier material is 1:1 to 1:11. The oral solid preparation can be tablets, capsules or granules and has the advantages of low side effects, high bioavailability, high safety, small toxic and side effects, convenience in application and the like.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a curcumol solid dispersion and an oral solid preparation thereof. Background technique [0002] Zedoary is also known as black ginger, blue ginger, black ginger, alias Jiangqi, blue heart ginger; it belongs to the perennial herbaceous plant of the genus Curcuma in the family Zingiberaceae. It is mainly used to treat diseases such as bloating and pain in trusted subordinates, stagnation of Qi and blood, accumulation of Qi and blood, lumps in the abdomen, amenorrhea due to blood stasis in women, inability to eat and drink, and pain from bruises. Zedoary is rich in volatile oil, and its composition is quite complex, mainly sesquiterpenes and sesquiterpenes. Modern pharmacological studies have found that the extract of Curcuma Curcumae - Zedoary Curcuma Volatile Oil has good anti-tumor, anti-inflammatory and anti-viral effects. It has been confirmed that the an...
