Abstract

The invention discloses a strychnos alkaloid vesicle and a preparation method thereof, and a preparation containing the strychnos alkaloid vesicle and a preparation method thereof, and belongs to the field of medicinal preparations. The strychnos alkaloid vesicle is prepared from strychnos alkaloid, a nonionic surfactant and an additive. The strychnos alkaloid vesicle is preferably prepared into an external gel preparation. The strychnos transdermal administration external preparation has unique advantages on the medicament that: a novel vesicle administration system is applied; trandermal absorption of the medicament is increased; the clinical treatment effects are enhanced; and the toxic and side effects during oral administration and parenteral administration are avoided. The strychnos alkaloid vesicle can be applied to treatment of rheumatoid arthritis, ankylosing spondylitis, and the like.

Description

technical field [0001] The invention relates to total strychnine vesicles and a preparation method thereof, a preparation containing total strychnine vesicles and a preparation method thereof, and belongs to the field of pharmaceutical preparations. Background technique [0002] In the clinical practice of traditional Chinese medicine for thousands of years, Nuxychia has shown remarkable curative effect in the treatment of rheumatoid arthritis. Nuxychnosae is the mature seed of Strychnos nux-vomica L or S Pierriana A.w.Hill, which has the effects of dredging collaterals, relieving pain, dispelling stagnation and swelling, and is good at treating rheumatism and other diseases. It has been clinically used for nearly a thousand years. "Surgical Quansheng Ji" says that it "can search for rheumatism in the muscles and bones, and remove phlegm poison that coagulates outside the inner membrane of the skin." "Medical Compendium of Chinese and Western Records" highly praises it, say...
