Used as a topical nasal decongestant and vasoconstrictor in dentistry.
is a sympathomimetic amine used as a vasoconstrictor in local
anesthetic solutions. It has pharmacologic activity similar to that of Epinephrine but it is more stable than Epinephrine. In equal concentrations, Levonordefrin is less potent than Epinephrine in raising blood pressure, and as a vasoconstrictor.
