Due to atmospheric pollution, the air quality is decreasing year by year, and there are more and more asthma patients. Many patients go to the hospital for infusion treatment when they have an attack and do not use any medication during the remission period, not knowing that such treatment is extremely irregular. The infusion treatment of asthma attacks is inseparable from “hormones”, including dexamethasone, hydrocortisone, methylprednisolone, etc. Such intravenous infusion is a systemic drug, which brings side effects such as “femoral bone necrosis”, “peptic ulcer”, “peptic ulcer” and “peptic ulcer”. Peptic ulcer”, “centripetal obesity”, etc., and the use of antibiotics, which can easily cause dysbiosis and bacterial resistance, all of the above situations make people shudder. Why not work to reduce asthma attacks? There are separate hormone inhalers and inhaled bronchodilators, and there are also two-in-one ones, no matter which one it is, as long as the regular application can play a role in reducing the number of asthma attacks, the inhalation preparation mainly enters the airway, playing a role in reducing the airway inflammatory response and diastolic bronchial purpose, other aspects of side effects are minimal (note: after inhalation must be timely rinse mouth to reduce drug residues in the mouth), the specific usage for the first three months Twice daily inhalation treatment. If the asthma is basically controlled after three months without attacks, it can be gradually changed to once a day inhalation, and so on to once every other day, twice a week, asthma control for more than a year without attacks can try to stop the drug, if still can not stop the drug to the minimum dose of long-term maintenance inhalation, can play the purpose of asthma control, but also to avoid the side effects of systemic use of hormones and antibiotics, why not do it.
