The airways narrow and produce excess mucus, making it difficult to breathe. In essence, asthma is the result of an immune response in the bronchial airways. [3] The airways of asthma patients are "hypersensitive" to certain triggers, also known as stimuli (see below).
Asthma Attack Treatment Plan. If you’ve had asthma for a while, you start to know what might trigger an attack. ... In turn, this causes your airways to become inflamed. Although the cause of ...
As a result, inflammation and associated healing process leads to scar formation and tissue remodelling, which are symptoms that can be found in almost all asthmatics patients. Thus, asthma is a chronic inflammatory disorder of the airways. Asthma is divided into two subgroups: atopic (extrinsic) and non-atopic (intrinsic).
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
An anti-asthmatic agent, also known as an anti-asthma drug, refers to a drug that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies ...
Researchers say they have found the first new treatment for asthma attacks in 50 years. The injection dampens part of the immune system that can go into overdrive in flare-ups of both asthma and a ...
Asthma is a chronic condition that causes inflammation in your airway. During an asthma attack, which can range from mild to severe, the muscles surrounding your bronchial tubes narrow, making it ...
β 2-agonists are used to treat asthma, an inflammatory disease in the airways. The inflammation makes the bronchia sensitive to some factors in the environment, which causes bronchoconstriction. When this constriction occurs, the airways get narrow and it causes symptoms like wheezing, chest tightness, shortness of breath, and coughing.
