Tolerability of a Salmeterol Xinafoate/Fluticasone Propionate Hydrofluoroalkane Metered-Dose Inhaler in Adolescent and Adult Patients with Persistent Asthma: A 52-Week, Open-Label, Stratified, Parallel-Group, Multicenter Study

BACKGROUND: Many patients with asthma require an inhaled long-acting beta(2)-agonist (LABA) in addition to an inhaled corticosteroid to adequately control their disease. OBJECTIVE: The purpose of this study was to assess the long-term tolerability of a salmeterol xinafoate/ fluticasone propionate (SFC) hydrofluoroalkane metered-dose inhaler (MDI) at 3 different doses BID.
