Roles Classification
Biological Role(s): 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.
metabolite
Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
(via alkaloid )
Application(s): antihypertensive agent
Any drug used in the treatment of acute or chronic vascular hypertension regardless of pharmacological mechanism.
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.
vasodilator agent
A drug used to cause dilation of the blood vessels.
