Exercise induced asthma (EIA) is common in adolescents. Relvar® (Fluticasone furoate (FF)/Vilanterol (VI)) is a once daily inhaler with bronchodilator effect lasting 24 hours. Our objective was to investigate the short and long-term effects of FF/VI on EIA in adolescents. Ninety-three adolescent asthmatics aged 12-18 years were referred for evaluation of EIA. 44 patients had a positive exercise challenge test (ECT), 22 (22/44) were allocated to a single administration of salbutamol (400 µg) and 22 to FF/VI (92/22 µg) in a double blind, double dummy method to assess the short-term effect on EIA. Then they received FF/VI for 30-60 days and were reassessed by a repeat ECT 24-hours after the last dose.
