Description

Bitolterol is a beta 2-adrenergic agonist. Since it in itself is biologically inactive, bitolterol is considered a pro-drug. When administered it is activated within the lung by esterase hydrolysis to the active compound colterol catecholamine N-t-butyl-arterenol. Bitolterol was marked under the name tornalate and was indicated to prevent and treat of reversible bronchospasm associated with asthma or chronic obstructive pulmonary diseases. But that drug was withdrawn from the market by Elan Pharmaceuticals in 2001.
