吸入激素疗法(气雾剂)是目前治疗哮喘的首选方法,皮质激素有优异的抗炎、抗过敏作用,是唯一能消除和完全吸收炎症的药物;能降低气道的高反应性,抑制过敏反应,缓解气喘症状,并能预防气道和肺部的不可逆损伤;可对抗哮喘过程中释放的生物活性物质,能降低痰的黏度,便于咳出。医学研究表明:吸入糖皮质激素后,药物直接在呼吸道局部起作用,较小剂量(几百微克/天)即可达到局部抗炎作用;部分激素通过消化道和呼吸道吸收入血液,大多随即被肝脏“灭活”(即失去作用),故出现“三高症”等副作用的较为少见。但吸入激素也有副作用,如声 Inhaled hormone therapy (aerosol) is currently the preferred method of treatment of asthma, corticosteroids have excellent anti-inflammatory, anti-allergic effects, is the only drug that can eliminate and completely absorb the inflammation; can reduce airway hyperresponsiveness and inhibit allergies Reaction, relieve asthma symptoms, and can prevent irreversible damage to the airways and lungs; can be against the release of bioactive substances in the process of asthma, can reduce the viscosity of sputum, easy to cough. Medical studies have shown that: inhaled corticosteroids, the drug directly in the respiratory tract to play a part, a small dose (a few hundred micrograms / day) to achieve local anti-inflammatory effect; part of the hormone absorption through the digestive tract and respiratory tract into the bloodstream, most of them were Liver “inactivation ” (that is, loss of function), it appears “three high disease ” and other side effects are more rare. However, inhaled hormones also have side effects, such as sound
