Exercise induced asthma (EIA) is common in adolescents. (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. Adolescent asthmatics were referred for evaluation of EIA. Patients with a positive exercise challenge test, were allocated to a single administration of salbutamol and 22 to FF/VI 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 exercise test 24-hours after the last dose.
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.

Medications and placebos were provided by the hospital pharmacy and medications were given by the nurse. Randomization was generated by computer, independently of trial staff as described (Salbutamol inhaler + Ellipta placebo or FF/VI + placebo Salbutamol inhaler). Technicians performing the ECT, investigators and patients were blinded to treatment choice
