As an ester prodrug, bitolterol is hydrolyzed by esterases to its active metabolite colterol (N-t-butylarterenol). Colterol selectively binds to and activates beta-2 adrenergic receptors in bronchiolar smooth muscle, thereby causing stimulation of adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP). Increased intracellular cAMP levels cause relaxation of bronchial smooth muscle. This increases air flow and prevents bronchospasms and may eventually lead to an improvement of airway function.

説明Bitolterol is a prodrug that releases colterol on activation by esterases in the lung. Colterol is a direct-acting agonist, and the N-t-butyl group makes it β2-selective with a binding potency equivalent to that of isoetharine and terbutaline. The ester form is lipophilic, which helps to keep it local in the lung and resistant to COMT, which tends to increase its duration of action. Onset begins 2 to 4 minutes after administration, and the effect can last as long as 8 hours. It has a adverse effect profile similar to that of other β2-selective agonists, with less drowsiness and restlessness compared to other direct-acting agonists.
