There are many complexities to the treatment of infants and children with recurrent wheezing and asthma. The National Heart, Lung and Blood Institute's (NHLBI's) Expert Panel Report-3 (EPR-3), published in 2007, provides guidance to clinicians who care for infants and children with asthma. Since that time, many important clinical trials have further informed the evidence base available to clinicians. In this manuscript, new approaches to long-term therapy, intermittent fixed-dose and dynamic dose therapies, and emerging therapies for asthma are reviewed. Further, additional gaps in guideline-based care and areas for future research are discussed.
