Anticholinergics is a class of medication that blocks the neurotransmitter acetylcholine from binding with receptors in the central and peripheral nervous system. This medication is primarily utilized to treat certain respiratory disorders, overactive bladder symptoms, and Parkinson's disease. There are several other synonyms for anticholinergics that can be used interchangeably, including antispasmodics, parasympatholytics, and cholinergic antagonists. These medications work by inhibiting the parasympathetic nervous system, which ultimately reduces the body's natural reaction to certain stimuli. It is important to note that anticholinergics may produce side effects, such as dry mouth, blurred vision, and cognitive impairments.
