Cholinolytic (anticholinergic) drugs include drugs that prevent the interaction of acetylcholine with cholinergic receptors. There are two main types of cholinergic receptors: muscarinic (m-type) and nicotine-sensitive (n-type). Accordingly, drugs with a predominant m- or n-anticholinergic action are isolated. Some anticholinergics easily penetrate the BBB and bind central cholinergic receptors (benactisin, aprofen, trihexyphenidil, etc.). These drugs are often called central anticholinergics, although the presence of peripheral (antispasmodic) activity is by no means excluded. This group of drugs is used to treat hyperkinesis and parkinsonism (including medication).
