To review the basis for the estimated comparative daily dosages of inhaled corticosteroids for children and adults that are presented in the National Heart, Lung, and Blood Institute's Expert Panel Report 3; in addition, the pharmacodynamic and pharmacokinetic basis for potential clinical differences among inhaled corticosteroids is discussed. A complete MEDLINE search was conducted of human studies of asthma pharmacotherapy published between January 1, , and March 15, , followed by a PubMed search up until August , using ciclesonide, inhaled corticosteroids, and pharmacokinetics as key words.
Product information on each inhaled corticosteroid was also included. Comparative clinical trials of inhaled corticosteroids and systematic reviews for efficacy comparisons were evaluated. Extensive literature reviews, meta-analyses, and selected clinical studies that illustrate or represent specific points of view were selected. Pharmacodynamic and pharmacokinetic data extracted from previously published reviews and specific studies were included.
Pharmacodynamic characteristics glucocorticoid receptor binding and lung delivery determine the relative clinical efficacy and pharmacokinetic properties oral bioavailability, lung retention, systemic clearance and determine comparative therapeutic index of the inhaled corticosteroids.
Ultrafine particle meter-dose inhalers MDIs have not demonstrated superior asthma control or improved safety over older MDIs. All of the inhaled corticosteroids demonstrate efficacy with once-daily dosing, and all are more effective when dosed twice daily. Current evidence suggests that all of the inhaled corticosteroids have sufficient therapeutic indexes to provide similar efficacy and safety in low to medium doses.
Whether or not some of the newer inhaled corticosteroids offer any advantages at higher doses has yet to be determined. Todos los CSIs demuestran eficacia con una dosis diaria.
