All nerve agent victims are given atropine, which blocks muscarinic acetylcholine receptors.

The drug is a combination of UMEC, a long-acting muscarinic antagonist, and VI, a long-acting beta agonist, in a single inhaler.

Cocaine is a tropane alkaloid, which means that it contains the heterocyclic tropane group, making it somewhat similar in structure to atropine, which as we have seen is a commonly used antagonist of muscarinic acetylcholine receptors.

Christopoulous has suggested that this strategy might work against the M1 muscarinic acetylcholine receptor, a promising target for the treatment of cognitive deficits that has so far proved undruggable.

The drug, Anoro, is an inhaled combination of vilanterol, a long-acting beta-agonist that is designed to open the airways, and umeclidinium, a long-acting muscarinic receptor antagonist, which works to improve lung function.
