Ciclesonide, which is a new once daily inhaled corticosteroid, is an ester prodrug that requires hydrolyzation by endogenous esterases in the lung to form its active metabolite (B-9207-021). The activated ciclesonide has an approximately 100-fold greater affinity for glucocorticoid receptors compared with the parent compound and produces high local anti-inflammatory activity.
