Is singulair an anticholinergic

No, Singulair (montelukast) is not an anticholinergic. It is a leukotriene receptor antagonist used primarily to manage Asthma and allergic rhinitis by blocking the action of leukotrienes, which are chemicals in the immune system that contribute to inflammation and bronchoconstriction. Anticholinergics, on the other hand, work by blocking the action of acetylcholine and are typically used for respiratory conditions and other disorders.
