Pharmacologic therapy of asthma during pregnancy

Abstract

Asthma is a common, potentially serious medical complication during pregnancy. Optimal clinical and pharmacologic management is necessary to mitigate maternal and fetal complications. Mild asthma may be managed in most cases with inhaled beta 2-mimetics. Anti-inflammatory therapy is recommended for the treatment of moderate and severe asthma. Based on limited human experience, beclomethasone is currently the recommended inhaled corticosteroid during pregnancy. However, other inhaled corticosteroids may have advantages compared to beclomethasone because of reduced systemic absorption, which may adversely affect intrauterine growth. Based upon theoretic considerations, theophylline is now considered a secondary therapy, but data demonstrating the superiority of inhaled corticosteroids versus theophylline during pregnancy are lacking.
