Abstract

The invention discloses a compound radix angelicae pubescentis transdermal patch used for treating rheumatism and a preparation method thereof. The Chinese herb compound is prepared from radix angelicae pubescentis, angelica sinensis, cassia twigs, ash bark and cyperus rotundus. A volatile oil mixture of the Chinese herb compound is extracted, then a transdermal patch matrix is prepared, the volatile oil extract of the Chinese herb compound, indometacin and borneol are dissolved with 75% ethyl alcohol and then evenly mixed with the matrix, the medicine is evenly applied on a back layer, a polyacrylic resin pressure-sensitive adhesive is smeared around the medicine, the product is covered with release paper and cut to have a regulated area, and the transdermal patch is obtained after sealed packaging. The patch can stop pain rapidly and prevent stimulation to the gastrointestinal tract, the liver and the kidneys from indometacin.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine, and relates to a Duhuo compound patch for treating rheumatism and a preparation process thereof. technical background [0002] Duhuo is the dry root of the Umbelliferae plant Angelica Placiformis. Traditional Chinese medicine believes that Duhuo has the effects of dispelling wind and dampness, dispelling cold and relieving pain. Commonly used for anemofrigid-damp arthralgia, waist and knee pain, Shaoyin headache, etc. Modern research proves that its active ingredients are coumarin compounds and some alcohols and esters, so the extracted volatile oil has higher active ingredients. [0003] The existing Duhuo compound preparations are mostly volatile oil liniments. Because the volatile oil has strong volatility, the drug release amount of the liniments is small, which cannot meet the long-term administration needs of rheumatism patients, and the dosage is inaccurate. In addit...
