剂量计数装置在呼吸道给药领域的应用与发展

The Application and Development of Dose Counters in Respiratory Medication

吸入制剂是治疗呼吸道疾病的首选药物。由于国内的吸入产品起步较慢,导致国内吸入产品市场的外企垄断,以及相关制剂处方研究、药物递送装置、剂量计数装置的发展也落后于欧美等发达国家。本文介绍了在传统吸入制剂给药递送装置上集成机械或电子的剂量计数器,通过视觉和听觉的方式提醒患者在药物用尽前做好新品的更换,提升了患者的用药体验,更降低了药物用尽的急救风险。

Inhalation preparation is the choice drug of respiratory disease. Because the development of inhalation product started late, the whole market was already controlled by foreign companies. The development of formulation research, drug delivery device and dose counter also lags behind developed Europe and America. In this article, the dose counter, mechanical or electronic, integrated to traditional inhalation device was introduced. By visual and auditory, patients can replace their finished drug when the dose counter remind them to do so. The use of dose counter not only enhance the experience of patients, but also reduce the probability of emergency when without drug.
