Anticholinergic drugs are medicinal substances that block the action of the natural mediator – acetylcholine – on the cholinergic receptors. This group of medication is called “deliriants” due to the ability to cause delirium
The main effect of the anticholinergic drug is to block the cholinergic receptors and the impossibility of affecting them with a mediator – acetylcholine. For example, in the bronchi blocked receptors located in the smooth muscles.
Depending on which receptors are affected by anticholinergic drugs, the list is divided into broad groups: M-cholinoblockers (atropine, scopolamine, ipratropium bromide). N-holinoblockers (pentamine, tubocurarine).
Depending on the selectivity of the action: Central, or non-selective (atropine, pyrensepine, platyphylline). Peripheral, or selective (ipratropium bromide).
