RESUMEN
Three open-label extension trials evaluated the safety of budesonide inhalation suspension (BIS; Pulmicort Respules) in 670 children (8 months-9 years of age) with mild-to-severe persistent asthma. Patients were randomized to receive either BIS or conventional asthma therapy (CAT) for 52 weeks. The percentage of patients who discontinued because of clinical adverse events was low and similar among the CAT (0.4%) and BIS (0.7%) groups. After adjusting for length of time in the studies, there were no clinically relevant differences between the BIS and CAT groups in the type, incidence, or intensity of adverse events; vital signs or physical examination outcomes; or changes in clinical laboratory evaluations or oral fungal cultures.

BACKGROUND: Inhaled corticosteroid therapy in severe persistent asthma has been shown to reduce or eliminate oral corticosteroid (OCS) use while retaining effective asthma control. OBJECTIVE: We sought to evaluate the ability of mometasone furoate (MF) delivered by means of dry powder inhaler to reduce daily oral prednisone requirements in OCS-dependent patients with severe persistent asthma. METHODS: We performed a 12-week, double-blind, placebocontrolled trial (21 centers, 132 patients) comparing 2 doses of MF (400 and 800 microg administered twice daily) with placebo, followed by a 9-month open-label phase in which 128 patients received treatment with MF. RESULTS: At the endpoint of the double-blind trial, MF 400 and 800 mg twice daily reduced daily OCS requirements by 46.0% and 23.9%, respectively, whereas placebo increased OCS requirements by 164.4% (P <.01). Oral steroids were eliminated in 40%, 37%, and 0% of patients in the MF 400 and 800 mg twice daily and placebo groups, respectively. Pulmonary function and quality of life significantly increased for MF-treated patients. Further reductions in OCS requirements were achieved with long-term MF treatment in the open-label phase. CONCLUSION: MF inhaled orally as a dry powder is an effective alternative to systemic corticosteroids in patients with severe persistent asthma.
