Bronchitis is an inflammation of the bronchi (lung airways), resulting in persistent cough that produces considerate quantities of sputum (phlegm). Bronchitis is more common in smokers and in areas with high atmospheric pollution.
Bronchodilators (also known as beta2-agonists* ) are non-steroid medications that help open up airways by relaxing small muscles which are tight due to asthma. Some bronchodilators are rapid-acting, and some are long-acting.
Rapid-acting bronchodilators are used as “rescue” or quick–relief medications to immediately relieve asthma symptoms. Quick relief bronchodilators are also sometimes prescribed to be taken before exercise to control exercise-induced broncho constriction. This type of medication is meant to be used to treat sudden asthma symptoms. If it is necessary to use a rescue medication on a daily basis, notify your doctor as it could mean that your asthma condition is not under control.
Long-acting bronchodilators are long-term medications which are used to manage and control asthma symptoms. They are typically prescribed to be taken twice daily—even when symptoms are not present.
