Answer to Question 1

ANS: A
Because steroid action involves modification of cell transcription, full antiinflammatory effects require hours to days. It is important for patients to understand that inhalation of an aerosolized steroid will not provide immediate relief as with an adrenergic bronchodilator. However, daily compliance with the inhaled medication is essential to controlling the inflammation of asthma.

Answer to Question 2

ANS: A
Ciclesonide, a prodrug, is given as an inactive compound and is converted to an active metabo-lite, desisobutyryl-ciclesonide (des-CIC), by intracellular enzymes.
