Once-daily evening administration of mometasone furoate in asthma treatment initiation.
BACKGROUND
In a previous study, a 200-microg once-daily evening dose of mometasone furoate dry powder inhaler (DPI) was effective in patients with asthma previously taking inhaled corticosteroids. No studies have been conducted to test the effect of a once-daily evening dose in patients previously using only short-acting beta2-adrenergic agonists (SABAs) for symptom relief.


OBJECTIVE
To evaluate the effectiveness of mometasone furoate DPI administered once daily in the evening as initial controller therapy in patients previously using SABAs alone for asthma.


METHODS
Patients with mild-to-moderate persistent asthma from 18 US centers participated in a 12-week, randomized, double-blind, placebo-controlled study. Patients received either mometasone furoate DPI, 200 microg, or placebo once daily in the evening. The primary efficacy variable was the change in forced expiratory volume in 1 second from baseline to the end point (last evaluable visit). Other measurements included forced vital capacity, forced expiratory flow between 25% and 75%, morning and evening peak expiratory flow, asthma symptoms, use of albuterol, nocturnal awakenings, physicians' evaluation of response to therapy, and time to asthma worsening.


RESULTS
At the end point, the mean increase in forced expiratory volume in 1 second relative to baseline for the mometasone furoate DPI group of 0.43 L (16.8%) was significantly greater than that for the placebo group of 0.16 L (6.0%) (P < .01). Morning peak expiratory flow, forced vital capacity, and forced expiratory flow between 25% and 75% also significantly improved with mometasone furoate DPI treatment relative to placebo (P < .01). Once-daily dosing with mometasone furoate DPI was well tolerated.


CONCLUSIONS
Mometasone furoate DPI (200 microg) administered once daily in the evening significantly improves pulmonary function in patients previously using SABAs alone for asthma control.
