TCM TREATMENT
Epinephrine and intravenous aminophylline are the drugs of choice for the emergency management of acute asthma. However, for status asthmaticus or for acute attacks in epinephrine-resistant patients, the adrenal corticosteroids are usually necessary. Intravenous hydrocortisone and methylprednisolone are the preparation of choice. But epiniphrine should not be used in patients with hypertension or angina or in elderly patients.
Epinephrine ( 1 : 1000), 0.2-0.5 rdl subcutaneously, is the initial drug of choice and may be repeated every 1 to 2 hours.
Aminophylline, 250mg in 10-20ml saline administered slowly and intravenously, can be prescribed if epinephrine is not effective. Oral dose of aminophylline is usually lOOmg, 4 times daily.
Isoproterenol (1:200), 1-2 inhalations from a hand nebulizer every 30 to 60 minutes, is most effective in mild attacks.
Corticosteroid drugs are most effective in.severe heart attacks that do not respond satisfactorily to the bronchodilators.
Prednisone is given 40-60mg/d in divided doses and gradually reduced to nil over 7 to 10 days.
