What class of drug is atrovent?

Atrovent, the brand name for ipratropium bromide, belongs to the class of drugs known as anticholinergics or muscarinic antagonists. It is primarily used as a bronchodilator to relieve symptoms of bronchospasm in conditions like chronic obstructive pulmonary disease (COPD) and Asthma. Atrovent works by blocking the action of acetylcholine on the airway smooth muscle, leading to relaxation and dilation of the airways.
