Abstract

The invention discloses a swelling-resistant pharmaceutical composition. The swelling-resistant pharmaceutical composition comprises aescine A or salt thereof, aescine B of salt thereof and diethylamine salicylate according to the proportion of (0.3-1.5):(0.5-1):(2-5). The invention further discloses a compound aescine A and B liposome hydrogel patch containing the swelling-resistant pharmaceutical composition and a preparation method of the compound aescine A and B liposome hydrogel patch. Compared with the prior art, the compound aescine A and B liposome hydrogel patch is good in transdermal absorption effect, swelling-resistant effect and safety.

Description

technical field [0001] The invention belongs to the field of pharmacy, and relates to an anti-swelling pharmaceutical composition, and also relates to a compound aescin A, B liposome hydrogel patch containing the composition and a preparation method thereof. Background technique [0002] Aescin, also known as aescinic acid, is a general term for total saponins, β-aescin or isoaescin, etc. extracted from the seeds of Aesculus in the family Aescinaceae, belonging to triterpenoid saponins. The water solubility of aescin is poor, in order to increase its solubility, it is often made into sodium salt. Studies have shown that the components with higher content in aescin are aescin A, B, C, and D. Aescin can reduce pathological increased capillary permeability, increase venous tension, reduce inflammatory substance exudation, have anti-inflammation, detumescence, pain relief, improve blood circulation, and promote the recovery of acute closed soft tissue injury.
