dopaminergic antagonist
A drug that binds to but does not activate dopamine receptors, thereby blocking the actions of dopamine or exogenous agonists.
serotonergic antagonist
Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or serotonergic agonists.
drug metabolite
alpha-adrenergic antagonist
An agent that binds to but does not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous alpha-adrenergic agonists. alpha-Adrenergic antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.
