Antikolinergics are a class of drugs that block the action of acetylcholine, a neurotransmitter in the brain and body. Acetylcholine plays a crucial role in various bodily functions, including muscle contraction, heart rate regulation, and learning and memory. By inhibiting acetylcholine's effects, anticholinergics can have a wide range of therapeutic uses and also potential side effects.

Therapeutic applications of anticholinergics include treating conditions like Parkinson's disease, where they help to reduce tremors and muscle stiffness. They are also used to manage symptoms of overactive bladder by relaxing the bladder muscles, and to treat certain types of gastrointestinal disorders by slowing down bowel movements. Some anticholinergics are employed to counteract motion sickness and as adjuncts in anesthesia to reduce secretions.

However, blocking acetylcholine can also lead to unwanted side effects. These commonly include dry mouth, blurred vision, constipation, urinary retention, and increased heart rate. In the central nervous system, anticholinergics can cause drowsiness, confusion, dizziness, and memory impairment, particularly in older adults. Due to these potential cognitive effects, their use is often carefully considered in elderly populations. The specific side effects and their severity depend on the particular anticholinergic drug, the dosage, and individual patient factors.
