nadolol
METHODS: The authors       conducted a double-blind, randomized, crossover, placebo-controlled study to test       the hypothesis that a nonselective beta-blocker--nadolol--enhances       vasoconstriction induced by the epinephrine contained in local anesthetic, thus       resulting in an increased duration of anesthesia.
