NCIt definition : The hydrochloride salt form of clonidine, an imidazoline derivate and centrally-acting
alpha-adrenergic agonist as well as antagonist with antihypertensive activity. Clonidine
hydrochloride binds to and stimulates central alpha-2 adrenergic receptors, thereby
decreasing sympathetic outflow to the heart, kidneys, and peripheral vasculature.
The reduction in sympathetic outflow, leads to decreased peripheral vascular resistance,
decreased blood pressure, and decreased heart rate.;
Alternative definition : NCI-GLOSS: A drug used to treat high blood pressure. It is also being studied in the
treatment of certain types of cancer pain. It blocks the release of chemicals from
nerve endings that make blood vessels constrict (get narrower). Catapres is a type
of antihypertensive agent and a type of alpha-adrenergic agonist.;
