Asthma is a chronic disease that affects the airways, which are the tubes that carry air into and out of the lungs. When you have asthma, the inside walls of your airways are inflamed (swollen). The inflammation makes the airways very sensitive, and they tend to react strongly to things that you are allergic to or find irritating. When the airways react, they narrow and constrict the airflow to your lungs. This is called bronchospasm. It causes asthma symptoms like wheezing (a whistling sound when you breathe), coughing, tightness in the chest, and trouble breathing.
While there is no asthma cure, asthma can be controlled. There are many different asthma treatments, and Ventolin is one of the most basic and most important types of treatment for asthma relief. Ventolin is a “rescue” asthma inhaler, which can help improve breathing very quickly. Even if you take other asthma controller medications, it is important to always have a rescue asthma medication available to relieve an attack.
Ventolin is approved to both treat and prevent asthma attacks. Because Ventolin (http://asthma-inhalers-online.com/buy-generic-ventolin-online.html) is short-acting, it is not necessarily the best asthma medication for preventing asthma attacks. However, it is an excellent medication for treating asthma attacks or preventing exercise-induced asthma attacks (see Asthma and Exercise).
Asthma is not the only cause of bronchospasms. Ventolin can also treat bronchospasms due to other lung problems, such as chronic obstructive pulmonary disease (COPD), including emphysema or chronic bronchitis.
