Master Anticholinergic Agents in 2026 – Ace Your Pharmacology Practice Test with Confidence!

Anticholinergic agents work primarily by blocking the action of acetylcholine on muscarinic receptors in the body. In the case of the airways, acetylcholine is responsible for stimulating glandular secretion, including the production of mucus. By inhibiting this action, anticholinergic agents effectively reduce the secretion of mucus in the airways.

This reduction in mucus production can be beneficial in conditions such as asthma or chronic obstructive pulmonary disease (COPD), where excessive mucus can lead to airway obstruction and difficulty breathing. By decreasing the volume of mucus, these agents help to improve airflow and decrease the risk of complications associated with mucus overproduction.

The other choices do not align with the pharmacological effects of anticholinergic agents. For example, increasing mucus production or enhancing mucus clearance would contradict the primary action of these medications, which aims to reduce excessive secretion and improve respiratory function.
