Asthma is a chronic inflammatory disease of the airways involving a variety of cells, especially mast cells, eosinophils and T-lymphocytes, and is characterized by episodes of expiratory dyspnea with croup. There are more drugs for asthma. Asthma drug classification: 1, bronchodilators: β2 agonists, anticholinergics, theophylline 2, anti-inflammatory drugs: glucocorticoids, leukotriene modulators common asthma drug effects and side effects: 1, short-acting β2 agonists (Ventolin aerosol and nebulizer, asthma Contrast aerosol, Boliconi, isoprenaline hydrochloride aerosol) Action: bronchodilator, fast-acting, short duration ( 4-6 hours). 4-6 hours). Used for first aid in asthma attacks. Side effects: palpitations, hand tremors, muscle tremors, long-term application causes beta2 receptor function downregulation and increased airway reactivity. How to avoid: use with caution in patients with hyperthyroidism and heart disease; not for long-term application; not for overdose; less side effects by inhalation than by oral administration. 2.Long-acting β2 agonists (salmeterol-sulforaphane, formoterol-oxydubol, sinequan dubol) Effects: Bronchodilator, anti-inflammatory, synergistic with inhaled glucocorticoids. Lasts up to 12 hours. Formoterol has a faster onset of action and can be used as an emergency. Side effects: Palpitations, hand tremors, muscle tremors, less side effects than short-acting beta2 agonists. How to avoid: should not be applied alone, should be combined with glucocorticoids with moderate and severe patients, avoid large amount of application. 3.Anti-cholinergic drugs (AiQuanLuo aerosol, nebulizer) Effects: Diastolic bronchial, faster onset of action. Mainly used for asthma emergency, with little effect on the heart. Side effects: accelerating heart rate; difficulty in urination in men; aggravating glaucoma; thick sputum How to avoid: prohibited for patients allergic to atropine; caution for patients with glaucoma; caution for patients with prostate hypertrophy; caution for patients with severe arrhythmia. 4. theophylline (aminophylline, theophylline extended-release tablets) Effects: bronchodilator, anti-inflammatory effect. Should be used in combination with glucocorticoids and other drugs. Side effects: nausea, vomiting, loss of appetite, insomnia, tachycardia, heart rate disorders, convulsions, sudden drop in blood pressure, and the therapeutic dose of theophylline is very close to the toxic dose. How to avoid: Do not overdose application. Theophylline extended-release tablets 1-2 tablets per dose, twice daily. Those who take the drug for a long time should have their blood drawn regularly to test theophylline blood concentration. 5.Inhaled glucocorticoids (Pramipexole, Co-cortisone Aerosol, Sulforaphane, Cymbalta) Effects: Anti-inflammatory effect, reduce airway hyperresponsiveness. Control symptoms and improve lung function. It is the main drug for the treatment of asthma. Side effects: sore throat, fungal infection of the pharynx, small systemic side effects, weight gain, increased blood sugar, osteoporosis. How to avoid: Rinse your mouth after use and spit out the mouthwash, swallow some food if necessary to reduce residual medication in the pharynx. Combine with other drugs to reduce hormone dosage in patients with moderate or severe asthma. 6.Oral glucocorticosteroid (prednisone) Effects: Stronger than inhaled glucocorticosteroids, suitable for people with acute asthma attacks, severe asthma and those who will not use inhalation devices. Side effects: Long-term use may lead to weight gain, increased blood sugar, osteoporosis, lower immunity, hypokalemia, etc. How to avoid: Try to avoid long-term application. Asthma treatment should be based on inhaled glucocorticoids. If long-term application is needed, regularly test blood sugar, blood potassium, blood pressure and bone density. 7.Leukotriene modulator (cisplatin) Effects: Reduce airway inflammation and decrease airway hyperresponsiveness. It is only suitable for mild asthma alone. Patients with moderate or severe asthma should apply glucocorticoids in combination. It is easy to take once a day. It is also effective in allergic rhinitis, so it is suitable for asthma patients with allergic rhinitis. Side effects: Minor, with occasional headache and insomnia. Patients with asthma must pay attention to rest, drink more water and have fresh indoor air during the medication. When suffering from colds and bronchitis, coughing and sputum production often occur. Use cough expectorant drugs in a timely manner to keep the respiratory tract unobstructed. In terms of diet, diversify your diet, mix coarse and fine, do not eat too fine, and strengthen your body resistance.
