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 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.
Anti-asthmatic agents, also known as anti-asthma drugs, refer to drugs 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 and ...
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 ...
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 triggers are factors or stimuli that provoke the exacerbation of asthma symptoms or increase the degree of airflow disruption, which can lead to an asthma attack. [1] An asthma attack is characterized by an obstruction of the airway , hypersecretion of mucus and bronchoconstriction due to the contraction of smooth muscles around the ...
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 ...
[citation needed] These medications decrease immune system activity which in turn will decrease swelling of the airways, decrease airway resistance, and increase delivery of air to the alveoli during respiration. Unlike the SABAs, these medications do not provide relief of acute symptoms or asthmatic attacks, and their benefits are typically ...
