Bronchoconstrictor

A bronchoconstrictor is a type of drug that acts to constrict or narrow the airways of the lungs, which are known as the bronchial tubes. This activity is intended to reduce the symptoms of asthma and other respiratory disorders, such as coughing and wheezing. Bronchoconstrictors work by narrowing the airways by causing the smooth muscles surrounding them to contract. This can reduce the amount of air that can pass through, which helps to reduce the symptoms of asthma and other respiratory conditions. Bronchoconstrictors are typically used as part of a combination of drugs for the treatment of asthma, and may be used in both acute and chronic cases.
