what are bronchodilators
Solution
Bronchodilators are a type of medication that makes breathing easier by relaxing the muscles in the lungs and widening the bronchi (airways). They are used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). There are three types of bronchodilators: beta-agonists, anticholinergics, and theophylline. These can be short-acting (working for 4-6 hours), long-acting (working for up to 12 hours) or ultra-long-acting (working for up to 24 hours). They can be taken using an inhaler or a nebulizer.
