Particle size of inhaled corticosteroids: does it matter?

J Allergy Clin Immunol. 2009 Dec;124(6 Suppl):S88-93. doi: 10.1016/j.jaci.2009.09.050.

Abstract

A question with respect to asthma therapy revolves around the issue of whether better efficacy occurs with an ultrafine-particle inhaled corticosteroid because of better lung deposition into the distal airways. This article reviews particle size and delivery devices of different steroids, clinical outcomes of small- versus large-particle steroids, and the issue of pharmacoeconomics.
