Fluticasone alone or in combination with salmeterol vs triamcinolone in asthma.
Chest 1999 September
OBJECTIVES: To compare the efficacies of medium-dose fluticasone propionate (FP), medium-dose triamcinolone acetonide (TAA), and combined low-dose FP plus salmeterol (SL).
DESIGN: Randomized, double-blind, triple-dummy, multicenter, 12-week clinical trial.
SETTING: Allergy/respiratory care clinics.
PATIENTS: Six hundred eighty patients with asthma previously uncontrolled with low-dose inhaled corticosteroids.
INTERVENTIONS: FP, 220 microg bid; TAA, 600 microg bid; or FP, 88 microg plus SL, 42 microg bid.
MEASUREMENTS AND RESULTS: Outcome measures included FEV1, peak expiratory flow (PEF), supplemental albuterol use, nighttime awakenings, asthma symptoms, and physician global assessment. Compared with TAA, 600 microg bid, treatment with FP 220, microg bid, significantly increased FEV1, morning and evening PEF, and percent symptom-free days, and significantly reduced rescue albuterol use, number of nighttime awakenings, and overall asthma symptom scores (p < or = 0.035). Improvements with low-dose FP, 88 microg, plus SL, 42 microg bid, were significantly (p < or = 0.004) greater than TAA, 600 microg bid, in all the aforementioned efficacy measures as well as percent of rescue-free days. Combined low-dose FP, 88 microg, plus SL, 42 microg bid, also significantly increased FEV1 and percent of rescue-free days, and significantly reduced albuterol use compared with medium-dose FP, 220 microg bid (p < or = 0.018). At endpoint, both FP, 220 microg bid, and FP, 88 microg, plus SL, 42 microg bid, significantly increased FEV1 by 0.48 L and 0.58 L, respectively, compared with 0.34 L with TAA, 600 microg bid.
CONCLUSION: In patients who are symptomatic while taking low-dose inhaled corticosteroids, medium-dose FP (440 microg/d) and combination treatment with low-dose FP (176 microg/d) plus SL (84 microg/d) are both more effective than medium-dose TAA (1200 microg/d) in improving pulmonary function and asthma symptom control.
