what is Mechanism of action of ipratropium?

Ipratropium is an anticholinergic medication that works by blocking the action of acetylcholine on muscarinic receptors in the airways. This inhibition leads to bronchodilation, reducing bronchospasm and facilitating easier airflow in conditions like Asthma and chronic obstructive pulmonary disease (COPD). Additionally, it helps decrease mucus secretion, further aiding respiratory function. The onset of action is typically within 15 minutes, making it effective for acute relief of respiratory symptoms.
