What medication is used to treat lung qi deficiency?

Generally, "fei qi fei" refers to pulmonary emphysema. Pulmonary emphysema can be treated with medications such as terbutaline sulfate nebulizer solution, salbutamol inhalation aerosol, salmeterol xinafoate aerosol, budesonide inhalation aerosol, and dexamethasone acetate tablets. If discomfort or symptoms occur, it is recommended to seek timely medical attention and receive standardized treatment under the guidance of a physician. Detailed analysis is as follows:

1. Terbutaline Sulfate Nebulizer Solution

Terbutaline sulfate nebulizer solution works by stimulating β2-adrenergic receptors, increasing intracellular cyclic adenosine monophosphate (cAMP) levels, thereby promoting relaxation of bronchial smooth muscles. It has a strong bronchodilatory effect and effectively relieves wheezing symptoms. Additionally, terbutaline sulfate nebulizer solution can inhibit the production of inflammatory mediators such as leukotrienes, reducing airway inflammatory responses, thus aiding in the treatment of pulmonary emphysema.

2. Salbutamol Inhalation Aerosol

Salbutamol inhalation aerosol is a short-acting β2 receptor agonist that rapidly relaxes airway smooth muscles and increases airflow, thereby alleviating breathlessness in patients with pulmonary emphysema.

3. Salmeterol Xinafoate Aerosol

Salmeterol xinafoate aerosol is a long-acting β2 receptor agonist that not only relaxes bronchial smooth muscles but also reduces the release of inflammatory mediators, thereby mitigating airway inflammation. Salmeterol xinafoate aerosol is typically used in combination with corticosteroids to form a combination preparation for treating mild to moderate stable-phase pulmonary emphysema. This combination therapy helps relieve symptoms of emphysema through dual mechanisms: bronchodilation and reduction of inflammatory responses.

4. Budesonide Inhalation Aerosol

Budesonide inhalation aerosol is a corticosteroid with anti-inflammatory and immunosuppressive properties. It reduces airway inflammation by inhibiting the accumulation and activation of inflammatory cells and decreasing the release of inflammatory mediators.

5. Dexamethasone Acetate Tablets

Dexamethasone acetate tablets are a type of corticosteroid with anti-inflammatory, anti-toxic, and immunosuppressive effects. They inhibit the aggregation and activation of inflammatory cells, prevent leukocyte infiltration, and reduce the release of inflammatory substances. Administered orally or via inhalation, dexamethasone acetate tablets help reduce airway inflammation and improve symptoms in patients with pulmonary emphysema.

It is recommended to strictly follow medical instructions when using these medications, paying close attention to potential side effects and drug interactions, to ensure safe and effective treatment.
