Inhaled high-dose beclomethasone in chronic asthma.
The effects of high-dose inhaled beclomethasone dipropionate were studied retrospectively in 123 asthma patients who were inadequately controlled on standard doses of beclomethasone dipropionate, or who required oral corticosteroids to control their asthma. High-dose beclomethasone dipropionate was administered by aerosol which delivered 250 micrograms beclomethasone dipropionate per metered dose. Thirty-one percent of the steroid-dependent patients (n = 65) were able to stop maintenance oral steroid after the introduction of beclomethasone dipropionate 250 and a further 48% were able to reduce their daily dosage. The mean reduction in daily maintenance prednisone was 5.2 mg. Comparing a six month period before and during treatment with beclomethasone dipropionate 250, asthma control was improved in 69% of all patients. This was accompanied by a 53% reduction in the number of acute attacks requiring supplementary courses of oral corticosteroid and a 70% reduction in admissions to hospital. Prior to beclomethasone dipropionate 250, 21% of the steroid-dependent patients were maintained on alternate day prednisone whereas after the introduction of beclomethasone dipropionate 250, 44% of those 45 still requiring continuous prednisone were maintained on an alternate-day regimen.
