[Use of inhaled beclomethasone dipropionate in adult asthma].

Beclomethasone dipropionate has now been used for more than 10 years during which our knowledge of how to use inhaled corticosteroids has gradually improved: high dose initial treatment followed by progressive reduction down to the minimum effective dosage; administration in 2 daily doses when the asthma is stable and 4 daily doses in case of instability; mild and transient undesirable effects, often minimized by a correct use of the inhaler; effectiveness assessed from bronchial hyper-reactivity and respiratory function tests, reduction or avoidance of oral corticosteroid therapy, or results of association with other treatments, and in particular bronchodilators. When exactly should inhaled corticosteroid therapy should be started and how long should it be pursued are controversial points, but an early and prolonged treatment must probably be recommended.
