| Description | Levobupivacaine-d9 is intended for use as an internal standard for the quantification of levobupivacaine (Item No. 31596) by GC- or LC-MS. Levobupivacaine is a sodium channel blocker and local anesthetic, as well as the levorotary stereoisomer of bupivacaine (Item No. 16618).1,2,3 It inhibits cardiac sodium channel currents (INa) by 57.8% in isolated guinea pig ventricular myocytes when used at a concentration of 10 μM.1 Levobupivacaine (10 μM) reduces the maximal rate of depolarization (Vmax) and action potential duration to 76.7 and 83.4% of controls, respectively, in isolated guinea pig papillary muscle.2 It induces a complete block of proprioception, motor function, and nociception in the hindleg of rats when administered at a dose of 7.7 mM by percutaneous injection into the sciatic nerve.3WARNING This product is not for human or veterinary use. | | References | [1] C VALENZUELA.
