Pharmacokinetic comparison of beclomethasone dipropionate extrafine aerosol from two inhaler devices in children with asthma

摘要

Objective. The primary objective was to test the comparability of the pharmacokinetics of beclomethasone dipropionate (BDP) delivered from a pressurized extrafine solution formulation in two inhalation devices in children with asthma. One inhaler was actuated using the press and breathe (P&B) technique and the other was breath-actuated (AH); both inhalers used HFA-134a as propellant.
