psychotropic drug
A loosely defined grouping of drugs that have effects on psychological function.
histamine antagonist
Histamine antagonists are the drugs that bind to but do not activate histamine receptors, thereby blocking the actions of histamine or histamine agonists.
muscarinic antagonist
A drug that binds to but does not activate muscarinic cholinergic receptors, thereby blocking the actions of endogenous acetylcholine or exogenous agonists.
serotonergic antagonist
Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or serotonergic agonists.
dopaminergic antagonist
A drug that binds to but does not activate dopamine receptors, thereby blocking the actions of dopamine or exogenous agonists.
antipsychotic agent
Antipsychotic drugs are agents that control agitated psychotic behaviour, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect.
