title: Bronchial asthma: some aspects of pathogenesis and therapy.
abstract: The first step in management of bronchial asthma is to exclude other diseases which may present as wheezing dyspena. Once the diagnosis is confirmed beyond a reasonable doubt, therapy can be initiated. Treatment depends on the type, severity, and duration of the disease. Other factors which dictate the choice of drug are the patient's response, metabolism of the drug, and complications of the disease. Theophylline forms the backbone of asthma therapy. Because of the wide variation in half-life of theophylline in different individuals due to variation in rate of metabolism and elimination, serum levels of theophylline should be monitored whenever possible. Newer antiasthmatic drugs, such as cromolyn sodium and inhaled steroids, are playing an increasing role in treatment of selected patients.
