What are common side effects associated with anticholinergic medications?

Anticholinergic medications work by blocking the action of acetylcholine in the body, which leads to a reduction in various bodily secretions and functions. The common side effects associated with these medications are primarily a result of this action.

Dry mouth occurs because anticholinergics reduce saliva production, leading to a lack of moisture in the mouth. Constipation is another frequent side effect, as these medications inhibit gastrointestinal motility, making it more difficult for food to move through the intestines. Urinary retention can result as well, since anticholinergics can relax the bladder’s detrusor muscle, impairing the ability to urinate comfortably. Lastly, blurred vision can occur because these medications can cause pupil dilation (mydriasis) and reduce the ability of the eye to focus, which affects vision.

Overall, the side effects listed encompass the anticholinergic effects on various systems in the body, confirming their relation to the unique mechanism of action of these drugs.
