Abstract

The invention discloses an external preparation (hydrogel transdermal patch) for preventing congealing cold blood stasis-type primary dysmenorrheal, and a preparation method of the hydrogel transdermal patch. The hydrogel transdermal patch comprises a back lining layer, a medicated substrate layer fixed on the back lining layer, and an anti-sticking layer covering the medicated substrate layer, wherein the medicated substrate layer comprises the following materials by weight: 20 to 60 parts of hydrogel substrate, 10 to 50 parts of volatile oil part, 20 to 70 parts of elution part, and 10 to 30 parts of transdermal penetration enhancer. The transdermal patch has the advantages that the active components are clean; the composition is scientific and reasonable; the drug loading capacity is relatively large; experiments show that the hydrogel transdermal patch is excellent anti-dysmenorrheal, anti-inflammatory and blood circulation activating activities, has a long-acting controlled release effect of slowly releasing medicine active ingredients for a long time, and is convenient to use, comfortable, and non-irritant and non-allergy to skin.

Description

Technical field: [0001] The invention relates to a traditional Chinese medicine composition and an external hydrogel patch, in particular to a traditional Chinese medicine composition transdermal patch capable of preventing and treating primary dysmenorrhea of ​​cold coagulation and blood stasis type and a preparation method thereof. Background technique [0002] Primary dysmenorrhea (PD) is the most common disease of female endocrine disorders. Its incidence rate is high, the lowest incidence rate is 33.19%, and the incidence rate in foreign countries is higher, with severe cases accounting for 15%. It affects the work and life quality of young women . Traditional medicine believes that the onset of dysmenorrhea is mainly caused by emotional injury, careless daily life or the harm of six evils, and is related to the fertile body, menstrual period, and the special physiological environment before and after menstruation. Its pathogenesis is mainly due to Chong Ren stasis or ...
