Individual one-hour post-dose steady state fluticasone propionate plasma concentrations. The mean±SD in pg/mL were as follows: 12–18 yr reference group, 76±61; 5–9 yr actuation alone, 87±80 (p=0.75); 5–9 yr VHC/mouthpiece, 207±149 (p=0.0006); 5–9 yr VHC/mask, 140±61 (p=0.07); and 1–4 yr VHC/mask, 165±58 (p=0.016). *Significantly lower than groups receiving FP through VHC (p=0.003).
