Abstract

The invention relates to a tulobuterol transdermal patch and belongs to the field of transdermal medicinal preparation. According to the tulobuterol transdermal patch disclosed by the invention, tulobuterol is prepared into a drug reservoir; the tulobuterol transdermal patch is prepared from tulobuterol, a penetration enhancer, carbopol and polysiloxane pressure sensitive adhesive; specific matrixcombination and use amount are utilized to for controlling drug release speed, and finally, the purpose of stably releasing drugs for 24 hours is achieved. The tulobuterol transdermal patch is pastedand applied before sleeping, and the plasma concentration can reach peak concentration from late night to early morning when a respiratory function of a patient is prone to reduce; thus, the respiratory function can be improved, a cumulative effect is avoided when the tulobuterol transdermal patch is continuously used, and untoward effects of drugs are reduced. Furthermore, the tulobuterol transdermal patch disclosed by the invention is less affected by environment change, can be stably stored for a long time and can be applied to long-time maintenance therapy of bronchial asthma and chronicobstructive pulmonary disease patients.

Description

technical field [0001] The invention relates to the field of transdermal pharmaceutical preparations, in particular to a tulobuterol transdermal patch and a preparation method thereof. Background technique [0002] Asthma is a common disease of the respiratory system. Its pathogenesis is mainly a chronic airway inflammatory disease caused by the participation of various inflammatory cells such as mast cells, eosinophils, thymic lymphocytes, CD4+T cells, and CD8+T cells. Now there are a variety of drugs for the treatment of asthma, mainly including: glucocorticoids, β2 receptor agonists, theophylline, anticholinergic drugs, leukotriene regulators and so on. Among them, β2 receptor agonists can quickly dilate bronchi to achieve anti-asthma effect, and are commonly used drugs for asthma treatment. Such drugs mainly include quick-acting and short-acting, quick-acting and long-acting, and chronic and long-acting. Tulobuterol is the third generation selective β2 adrenal receptor ...
