The drug "Salbutamol" is a drug of the group of adrenoagonists acting on beta receptors. The medication refers to selective substances that affect receptors located in the bronchi.
The effect of this drug is to provide them with a bronchodilator effect. This feature is used in medicine to stop attacks of bronchospasm, which occurs in a number of pathological conditions, mainly in bronchial asthma. The receptors in the heart are not activated and the cardiac activity does not change. The substance "Salbutamol" reduces the release of mediators of allergic reactions and inflammatory mediators, which also prevents bronchial edema, increasing their clearance. The pharmaceutical preparation “Salbutamol”, the instructions for use of which are given below, are available in various forms (tablets, aerosol, powder).
