Once-daily fluticasone furoate is efficacious in patients with symptomatic asthma on low-dose inhaled corticosteroids.

Background: Fluticasone furoate (FF) is an inhaled corticosteroid (ICS) with 24-hour activity in development as a once-daily treatment for the long-term management of asthma.

Objective: To assess the efficacy and safety of 4 doses of once-daily FF administered using a dry powder inhaler in patients (≥12 years) with moderate asthma, uncontrolled on low-dose ICS (fluticasone propionate [FP] 200 μg/day or equivalent).

Methods: This double-blind, placebo-controlled, dose-ranging study randomized 622 patients to 1 of 6 treatments: FF (100, 200, 300, or 400 μg) once daily in the evening, FP 250 μg twice daily (active control), or placebo for 8 weeks.

Pharmacokinetic, pharmacodynamic, efficacy, and safety data from two randomized, double-blind studies in patients with asthma and an in vitro study comparing two dry-powder inhalers delivering a combination of salmeterol 50 microg and fluticasone propionate 250 microg: implications for establishing bioequivalence of inhaled products.

Background: The use of dry-powder inhalers (DPIs) to administer respiratory medicines is increasing, and new DPIs are likely to be developed because of expiring patents. However, there is considerable debate concerning the extent to which DPIs are interchangeable without altering disease control or the safety profile of the treatment.

Objective: This study was designed to compare the pharmacokinetic (PK), pharmacodynamic (PD), efficacy, and safety data for 2 DPIs delivering a combination of salmeterol 50 microg plus fluticasone propionate (FP) 250 microg (SFC 50/250) to investigate assumptions of bioequivalence.

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.

Methods: This 52-week, open-label, stratified, parallel-group study assessed SFC in patients with persistent asthma.
