NCIt definition : A synthetic antihypertensive methoxyphenoxy- 2-propanol derivative with no intrinsic
sympathomimetic activity, Carvedilol acts as a nonselective beta-adrenoceptor blocking
agent (S(-) enantiomer) and as an alpha 1-adrenoceptor blocker (R( ) and S(-) enantiomers).
Its acts more strongly on beta-receptors than on alpha 1-receptors, reduces peripheral
vascular resistance by vasodilation, and prevents reflex tachycardia (beta-blockade)
so that heart rate is either unchanged or decreased. Carvedilol also reduces renin
release through beta-blockade. (NCI04);
Alternative definition : NCI-GLOSS: A drug used to treat high blood pressure and certain heart problems. It
is also being studied in the prevention and treatment of side effects caused by some
anticancer drugs. Coreg blocks certain receptors on nerve cells and causes blood vessels
to dilate (widen). It is a type of antihypertensive agent and a type of antianginal
agent.;
