An Investigation of the Use of a Metered-Dose Inhaler(MDI) in Patients with Bronchial Asthma and the Pharmaceutical Instructions.

An investigation of the use of a MDI (Metered-Dose Inhaler) of β-Stimulants or Steroids was carried out on bronchial asthmatic patients. The use of a MDI for the cure of bronchial asthma is standard. However, due to the misuse of these medicines, serious adverse-drug-reaction have also emerged and the importance of their proper use has thus gained attention. The patients understood the effect to be 95% for β-stimulants and 84% for steroids. The patients understood the proper use or dose to be 73% for β-stimulants and 62% for steroids. However, the patients who understood the effect of the medicines did not necessarily comprehend their proper use. Especially, the ratio of patients who used the medicine according to the doctor's instructions numbered 56% for β-stimulants and 53% for steroids.These results suggest that it is important to supply the proper pharmaceutical instructions in order to use the MDI correctly for all patients.
