Resumen

Glucocorticoids (GC), administered topically or systemically, form the cornerstone of asthma therapy. Delivered systemically, GCs serve as a major component of rescue therapy for acute asthma exacerbations. They also serve as chronic supplemental therapy in patients with severe persistent asthma who remain symptomatic despite high-dose inhaled GC therapy. Inhaled GCs are now the preferred controller medication for all asthmatics except for those with the mildest disease.

Glucocorticoids have been used in the treatment of asthma for nearly 50 years, beginning soon after cortisone was first synthesized and following reports that cortisone and corticotropin were effective in the treatment of rheumatoid arthritis.^{34 Hench P.S., Kendall E.C., Slocomb C.H. , y al.

Inhaled GC preparations have been developed that, because of their high topical-to-systemic effects, have proven to be safe and very effective in the treatment of asthma. This article provides a broad overview of the structure, pharmacokinetics, and pharmacodynamics of both systemically administered and inhaled GCs.
