An anticholinergic agent is a substance that blocks the neurotransmitter acetylcholine in the central and the peripheral nervous system. Anticholinergics inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells. The nerve fibers of the parasympathetic system are responsible for the involuntary movement of smooth muscles present in the gastrointestinal tract, urinary tract, lungs, etc. Anticholinergics are divided into three categories in accordance with their specific targets in the central and/or peripheral nervous system: antimuscarinic agents, ganglionic blockers, and neuromuscular blockers.

Sample Sentences & Example Usage
Since the pathology underlying any effect of anticholinergic drugs on cognitive function likely takes years to manifest, if a patient is clearly benefiting from a drug in the short-term, but may not survive in the long term, any cognitive harm from the drug may be inconsequential, on the other hand, a healthier patient particularly concerned about future dementia risk, whether because of family history or other reason, may consider alternative treatments.
