To anticholinergic (anticholinergic) drugs include drugs that prevent the interaction of acetylcholine with cholinergic receptors. There are two main types of cholinergic receptors: muskarinochuvstvitelnye (m-type) and nicotinecontaining (n-type). Consequently there are drugs with predominant m - or n-holinoliticheskoe effect. Some anticholinergics can easily penetrate through the BBB and bind to Central cholinergic receptors (benactyzine, aprofen, trihexyphenidyl, etc.). These drugs are often called Central holinoblokatorami, although the presence of peripheral (spasmolytic) activity is not excluded. This group of drugs used for the treatment of hyperkinesis and parkinsonism ( including drug).
