Problems solved by technology

[0011] At present, the compound preparations of tranilast and albuterol sulfate for clinical use are only ordinary tablets and capsules, which are released slowly in the body after oral administration, and it is difficult to achieve complete release, which leads to a decrease in the bioavailability of the drug, thus making it effective. It is relatively slow, which affects the full play of the drug effect, and cannot achieve the ideal anti-asthma effect

The invention also relates to the application of compounds shown as formulas (I) and (II) or pharmaceutically allowed salts thereof in the preparation of an oral therapeutical agent for treating asthma.

Description

Field of invention: [0001] The invention relates to an oral therapeutic agent for asthma containing tranilast and salbutamol sulfate as active ingredients and the use of tranilast and salbutamol sulfate in preparing the oral therapeutic agent for asthma. Background technique: [0002] Research on respiratory diseases has progressed rapidly in the past 30 years, and the modern prevention and treatment of asthma has undergone major changes due to the in-depth study of the pathogenesis of asthma. In the past, it was believed that asthma was mainly IgE-mediated type I allergy: sensitized mast cells release granules that cause bronchial smooth muscle spasm and lead to reversible airway obstruction. The main treatment is the application of bronchodilators to relieve bronchospasm. At present, it is known that allergic inflammation of the airway is the main factor in the pathogenesis of asthma, which is far more harmful than airway smooth muscle spasm. Antiallergic drugs should be u...
