Аннотация: The effects of intranasal corticosteroids (INSs) on the hypothalamic–pituitary–adrenal (HPA) axis should be assessed for any to be marketed INS. The objective of this study was to assess the effects of fluticasone furoate nasal spray (FFNS) on cortisol production (as a measure of HPA axis function) following 6 wk of treatment with FFNS 110 μg once daily (QD) compared with placebo in pediatric patients with perennial allergic rhinitis (PAR). In this double‐blind, parallel‐group study, patients (n = 112) aged 2–11 yr with a 1‐yr history of PAR (6 months for patients aged 2–3 yr) were randomized in a 1:1 ratio to either placebo or FFNS. Serum cortisol (SC) concentrations and urinary cortisol (UC) excretion were measured over a 24‐h period at the randomization (baseline) and final treatment (week 6) visits for HPA axis evaluation in a domiciled environment (overnight in the clinic). Plasma samples were collected for FFNS at several time points over the 24 h after the final dose for pharmacokinetic analyses. FFNS was non‐inferior to placebo with respect to change from baseline (expressed as a ratio) in 24‐h SC weighted mean. The lower limit of the two‐sided 95% confidence interval (CI) for the treatment ratio was greater than the pre‐specified non‐inferiority margin of 0.8 (treatment ratio = 0.97, 95% CI 0.88–1.07). UC excretion over 24 h at baseline and end of treatment was similar between treatment groups; no patients had 24‐h excretion levels below normal range after 6 wk of treatment. Plasma concentrations of FFNS were generally non‐quantifiable (<10 pg/ml). Results of the current study indicate that FFNS 110 μg QD has no significant effect on HPA axis function in 2‐ to 11‐yr‐old pediatric patients with PAR.
