Bronchial asthma is a hyperreactive disease of the airways, which results in spasmodic constriction of the airways. Therefore drugs that constrict the bronchi are contraindicated, such as beta-blockers, and commonly used drugs that lower blood pressure, such as atenolol and propranolol. If you have hypertension, combined with bronchial asthma, you should choose other classes of antihypertensive drugs. In addition, most bronchial asthma is an allergic reaction, and many antibiotics are generally effective, so antibiotics are weak for asthma, and antibiotic drugs are not used for bronchial asthma. Commonly used medications for asthma include beta agonists, including salbutamol and terbutaline. Also inhaled glucocorticosteroids, which can be used as long-term in the stable phase.
