Levonordefrin is the (-)-enantiomer of nordefrin, a synthetic derivative of norepinephrine , that acts as a vasoconstrictor. 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. 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 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%. Formulations containing levonordefrin have been used in combination with local anesthetics in dentistry to prolong anesthetic effects.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
