Abstract

The invention discloses a transdermal drug delivery compound formula containing artemisinin or the derivatives of artenisinin. The compound cures malaria by way of ransdermal drug delivery and effectively prevents the recrudescence of plasmodium. The transdermal drug delivery compound of the invention contains recrudenscence or the derivatives of recrudescence, medium, latent solvent and transdermal enhancer. The transdermal drug delivery compound of the invention treats in vitro through skin, avoids the first pass effect of liver and the blood drug concentration is stationary and the use is convenient. Animal experiments prove that the transdermal drug delivery compound is capable of effectively killing plasmodium and has the function of effective anti-recrudescence. Besides, the stimulation to skin is little without causing allergy or toxicity.

Description

【Technical field】 [0001] The invention belongs to the technical field of medicine, and relates to a transdermal preparation containing artemisinin or a derivative thereof, a preparation method and application thereof. 【Background technique】 [0002] Artemisinin derivatives are powerful antimalarial drugs commonly used in clinical practice. When malaria parasites are severely resistant to drugs such as chloroquine and facida, artemisinin derivatives have excellent antimalarial effects and have a positive effect on brain-type malaria. Falciparum malaria such as malaria has a good therapeutic effect, and has no toxic and side effects, and is an ideal fast-acting, low-toxic malaria treatment drug. [0003] However, when artemisinin and its derivatives, especially artemisinin, are administered orally in tablets and capsules, there is a hepatic first-pass effect. In order to avoid the first-pass effect, pharmacists try to use suppositories for rectal administration and Injection ...
