A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.
Cholinergic agonists mimic the actions of acetylcholine.
Cholinergic transmission involves the neurotransmitter acetylcholine being released from nerve fibers, binding to designated receptors on other cholinergic nerve fibers and passing on the message to bring about a response. Stimulation of the cholinergic system (also known as the parasympathetic nervous system) causes vasodilatation, constriction of pupils in the eyes, secretion of sweat, saliva and tears, slow heart rate, mucus secretion in the respiratory tract and constriction of bronchioles.
The medicines listed in this category are used to increase salivation in patients who suffer from conditions of dry mouth.
