Anticholinergic drug

Anticholinergic drugs are medications that block the action of acetylcholine, a chemical in the brain and nervous system involved in many functions, including muscle movement and memory. By inhibiting this chemical, these drugs can help treat various conditions such as asthma, allergies, Parkinson's disease, and overactive bladder. However, they can also cause side effects like dry mouth, blurred vision, and constipation, especially in older adults. It's important to use these medications under medical guidance, as they can significantly impact the body’s functions and may interact with other drugs.
