Problems solved by technology

However, tranexamic acid has strong polarity and poor transdermal ability of aqueous solution. Directly making tranexamic acid into a simple skin external preparation seriously affects its curative effect.
[0006] At present, there is no self-developed external preparation of tranexamic acid for the skin, and it has been reported that a simple combination of tranexamic acid and other components (Chinese patent CN99800921.0, Chinese patent CN200580031837, Chinese patent CN201110122382.1), with To achieve whitening or prevent pigmentation, but this composition is complex, the mechanism is not clear, it has certain irritation and damage to the skin, and it mostly belongs to the field of cosmetics

Abstract

The invention relates to a tranexamic acid skin externally applied nano-preparation, as well as a preparation method and a use thereof. The nano-preparation is prepared from tranexamic acid, medicated oil, an emulsifier, pharmaceutical additives, a thickener and pure water. The tranexamic acid skin externally applied nano-preparation provided by the invention has good physiological skin compatibility and can effectively promote the percutaneous absorption of tranexamic acid, improve the effect of preventing or treating pigmentation of the tranexamic acid and avoid toxicity and side effects, which are caused by systemic administration of the tranexamic acid.

Description

technical field [0001] The invention belongs to the field of chemical pharmacy, and more specifically relates to a nano-preparation of tranexamic acid for external use on the skin, a preparation method and application thereof. The nano-preparation of tranexamic acid for external use of the present invention has good skin physiological compatibility, can effectively promote the percutaneous absorption of tranexamic acid, improve the effect of tranexamic acid in preventing or treating pigmentation, and avoid the effects of tranexamic acid Toxic side effects caused by systemic medication. Background technique [0002] Tranexamic acid is also called tranexamic acid, tranexamic acid, the chemical name is trans-4-(aminomethyl)cyclohexanecarboxylic acid, molecular formula: C 8 h 15 NO 2 , molecular weight: 157.21, has the following chemical structure: [0003] [0004] Tranexamic acid is an antifibrinolytic hemostatic drug. Since tranexamic acid is similar in structure to t...
