A pharmaceutical researcher is researching a brand-new asthma medication that reverses irritant-induced bronchoconstriction. A postvagotomy (total transection of the vagus nerve) group of laboratory guinea pigs and a normal research group are both used. Without receiving the study drug, irritants are administered to both groups, and changes in bronchial diameter are noted. Both groups are then exposed to the irritants once more while simultaneously receiving the research medicine. The study drug is most likely similar to which of the following medications?

Eductional Objective: Ipratropium, an anticholinergic agent and derivative of atropine, treats obstructive lung disease by blocking acetylcholine at muscarinic receptors, which prevents bronchoconstriction and reduces mucus secretion from tracheobronchial submucosal glands.
