title: Inhaled corticosteroid therapy: a substitute for theophylline as well as prednisolone?
abstract: Topical corticosteroid treatment can be successfully achieved by inhaled therapy and can effectively provide a safe substitute for oral steroids. More than 8 million patient years of experience gained over a decade of use of inhaled steroids has shown them to be acceptable to patients and clinicians, with side effects confined to the upper airway. At daily doses of 200 to 1600 micrograms BDP or the equivalent, minor systemic activity may occasionally be demonstrated but no adverse systemic side effects have been reported. The topical anti-inflammatory treatment provided by inhaled steroids thus compares favorably with prednisolone and with other asthma therapy with respect to morbidity and mortality, suggesting that inhaled steroids combined with an inhaled beta-agonist is a safe and comprehensive treatment for chronic asthma. This parallel attack on inflammation and bronchoconstriction can be achieved with a morbidity that is much less than that of asthma and also likely to be less than that of the frequently used combination of theophylline and inhaled beta-agonist. Twice-daily regimens of inhaled steroids over a dose range of 200 to 1600 micrograms BDP or the equivalent should enable most patients with chronic asthma to receive effective therapy without recourse to potentially more toxic oral bronchodilator or steroid therapy.
