What medicine should the old man take if he can't breathe?

There are many reasons for asthma in the elderly. If asthma occurs after exercise, it may be that the heart function is not good. Some drugs that dilate coronary arteries, such as isosorbide mononitrate, can be taken orally. If there are lung diseases, such as senile chronic bronchitis, chronic obstructive pulmonary disease, pneumonia, etc., bronchodilators can be used according to the specific conditions of patients. It's best to go to the clinic, make clear the cause and then give targeted treatment. If you use drugs indiscriminately, it may aggravate your condition.
