Which of the following is a common side effect of anticholinergic medications?

Anticholinergic medications work by blocking the action of acetylcholine at muscarinic receptors in the body, which leads to a reduction in secretions. One of the most common and well-known side effects associated with this class of drugs is dry mouth, also referred to as xerostomia. This occurs because acetylcholine normally stimulates salivary gland activity; when its action is inhibited, salivation decreases, leading to a dry feeling in the mouth.

This side effect is significant for patients taking anticholinergic medications, as it can also lead to difficulties with swallowing, increased dental problems, and a decrease in the overall quality of life. Understanding this side effect is crucial for healthcare providers, as they may need to implement strategies to manage dry mouth in patients who are prescribed these medications.
