Enteric solid preparation containing lycopene or resveratrol or melatonin and preparation method of enteric solid preparation

The invention relates to the field of medicine preparations, in particular to an enteric solid preparation containing lycopene or resveratrol or melatonin and a preparation method of the enteric solid preparation. The enteric solid preparation is prepared from an active ingredient resveratrol, a water-soluble and/or enteric carrier adjuvant and other pharmaceutic adjuvants. The water-soluble carrier adjuvant can serve as a water-soluble solid dispersion carrier. The enteric carrier adjuvant is an enteric polymer and can serve as an enteric solid dispersion carrier or enteric coating material. The enteric solid preparation containing resveratrol has good solubility in the intestinal tract, medicine is fast dissolved and released in the intestinal tract, and therefore absorption of resveratrol is increased, and the bioavailability of the enteric solid preparation is improved.
