Drugs for Preventing and Treating Asthma
Anticholinergic Drugs
Anticholinergic drugs, such asipratropiumandtiotropium, block acetylcholine from causing smooth muscle contraction and from producing excess mucus in the bronchi. These drugs are inhaled. These drugs further widen (dilate) the airways in people who have already been given beta-adrenergic drugs or an inhaled corticosteroid.
