Abstract

The aquogel type thiamazole plaster includes a back lining layer, a medicine matrix layer and a protecting film. The medicine matrix layer contains medicine thiamazole in 0.2-20 wt% of the medicine matrix layer, aquogel type contact adhesive material, cross-linking agent, pH regulator, humectant, tackifier medicine, transdermal promoter and water, . The present invention has high transdermal effect of medicine, good skin compatibility, high air and moisture permeability, lowered toxicity and side effect of medicine and other advantages, and is used for treating hyperthyroidism.

Description

Technical field [0001] The invention relates to a hydrogel type methimazole patch, which belongs to the technical field of medicine. Background technique [0002] Hyperthyroidism (hyperthyroidism for short) is a common endocrine disease caused by increased thyroid function and excessive secretion of thyroid hormones, leading to an increase in the basal metabolic rate. Thiamazole (also known as tapazole, methylthioimidazole, thiothiazole, mecarzolil) can inhibit the synthesis of thyroid hormones and is a representative drug for the clinical treatment of hyperthyroidism. Its chemical name is 1 -Methylimidazole-2-thiol, molecular formula: C 4 H 6 N 2 S (molecular weight: 114.16). [0003] At present, the commonly used preparation for clinical treatment of hyperthyroidism is methimazole tablets. Due to the short biological half-life of methimazole (less than 3 hours), the oral dose of the drug is large, the frequency of administration is frequent, and the treatment of patients is inc...
