近年来气雾吸入治疗已越来越广泛地应用于支气管哮喘。与口服给药相比,气雾吸入治疗具有起效快、用药量少、局部药物浓度高和全身副反应少等优点。以喘乐宁为例,口服每次2～4mg,而定量压力气雾剂吸入每次只有200μg,为口服量的1/10～1/20。气雾吸入方法有几种,以定量压力气雾剂(MDI)最为常用,如舒喘灵和喘康速气雾剂都属此类。体积小,便于携带和每次喷药量恒定为其优点。但患者必须正确操作,否则会影响疗效。产品说明书上介绍的吸药方
In recent years, inhalation of aerosol has been more and more widely used in bronchial asthma. Compared with oral administration, aerosol inhalation therapy has the advantages of rapid onset, less dosage, high local drug concentration and less systemic side effects. To salbutamol, for example, oral 2 ~ 4mg each time, while the quantitative pressure aerosol inhalation only 200μg, oral dose of 1/10 ~ 1/20. Several methods of aerosol inhalation, the most commonly used quantitative pressure aerosols (MDI), such as salbutamol and asthma speed aerosols fall into this category. Small size, easy to carry and the amount of each spray constant its advantages. However, patients must be correct operation, otherwise it will affect the efficacy.
