What is a common side effect of anticholinergic agents like Scopolamine?

Anticholinergic agents, such as Scopolamine, are known for their ability to block the action of acetylcholine at muscarinic receptors in the nervous system. This action can lead to several physiological effects, including a reduction in glandular secretions. One notable and common side effect of these agents is dry mouth, medically termed xerostomia. This occurs because the inhibition of acetylcholine interferes with the secretion of saliva from salivary glands, resulting in a dry sensation in the mouth.

Other potential side effects of anticholinergic agents include difficulty swallowing, constipation, urinary retention, and in some cases, confusion in elderly patients. However, dry mouth is a prevalent and easily recognized side effect that many patients experience when using these medications. Understanding this effect is important for managing the comfort and treatment of patients taking anticholinergic medications.
