Levonordefrin is the (–)-enantiomer of nordefrin, a synthetic derivative of norepinephrine (Item No. 16673), that acts as a vasoconstrictor.{39580} Levonordefrin (1-5 µg/kg) rapidly increases blood pressure and heart rate in anesthetized dogs and has a more potent effect on blood pressure than the dextronordefrin enantiomer.{39581} It also inhibits carbamylcholine-induced uterine contractions in isolated rat uterine strips (EC50 = 0.0032 µg/ml). Levonordefrin (0.514 and 1.542 mg/kg), in combination with mepivacaine (Item No. 23402) and administered via intraoral infiltration, increases systolic arterial blood pressure in anesthetized dogs, however, the effect is not dose-dependent and the increase is not greater than 5.33%.{39582} Formulations containing levonordefrin have been used in combination with local anesthetics in dentistry to prolong anesthetic effects.
