Asthma is the most common chronic childhood disease. Prevalence rates
are increasing, most likely secondary to increased air pollution, pove
rty, and increased urbanization, and improved conditions for dust mite
survival. This article attempts to summarize current pediatric asthma
therapy. It begins with a description of the nonpharmacologic aspects
of asthma therapy, then discusses the two major categories of asthma
drugs, including a discussion of the appropriate use of these medicati
ons.
