Asthma, also known as bronchial asthma, is a chronic inflammatory lung disease involving various types of granulocytes. The main symptoms exhibited by patients are wheezing, shortness of breath, chest tightness, and coughing. These symptoms typically occur in the early morning or at night. Currently, the medications used to treat asthma primarily include local inhalants and oral medications. The inhalants generally consist of a combination formulation of long-acting bronchodilators and corticosteroids. Additionally, oral medications may include leukotriene receptor antagonists and histamine receptor antagonists. (The use of these medications should be under the guidance of a doctor.)
