Le nébivolol: un bêta-bloquant pourvu de propriétés vasodilatatrices [Nebivolol: a beta blocker with vasodilator properties]

Nebivolol is a new cardioselective beta-blocking agent possessing vasodilatory properties involving the endothelium. This compound is a dl-racemic mixture. The d-enantiomer is responsible for the beta-blocking properties whereas the l-enantiomer induces a vasodilation via a nitric oxide (NO) mechanism. Nebivolol is an unique agent that appears promising for the management of patients with hypertension, coronary heart disease or congestive heart failure.
