Albuterol sulfate is not a hormone drug, but an asthma drug with bronchodilator effect. Albuterol sulfate, also known as albuterol, mainly acts on the trachea and the terminal fine bronchus to relax the smooth muscles on these parts to relieve the spasm of the airway. In addition, salbutamol sulfate also inhibits the secretion of inflammatory and allergic mediators by mast cells in the airways, reducing the irritation of these substances in the airways. Albuterol sulfate is commonly used in oral and inhalation formulations, both of which are mainly used in clinical practice for the relief and treatment of bronchial asthma, or asthmatic bronchitis and other respiratory diseases with bronchospasm, as well as for the treatment of severe acute asthma attacks and allergic bronchospasm.
