Levobupivacaine

Levobupivacaine is an amino-amide local anaesthetic drug belonging to the family of n-alkylsubstituted pipecoloxylidide. It is the S-enantiomer of bupivacaine. Levobupivacaine hydrochloride is commonly marketed by AstraZeneca under the trade name Chirocaine. Compared to bupivacaine, levobupivacaine is associated with less vasodilation and has a longer duration of action. It is approximately 13 per cent less potent (by molarity) than racemic bupivacaine.Levobupivacaine is indicated for local anaesthesia including infiltration, nerve block, ophthalmic, epidural and intrathecal anaesthesia in adults; and infiltration analgesia in children. Adverse drug reactions (ADRs) are rare when it is administered correctly. Most ADRs relate to administration technique (resulting in systemic exposure) or pharmacological effects of anesthesia, however allergic reactions can rarely occur. (In Vitro) :Levobupivacaine (0-4 mM; 24 h) does not affect the viability of GES-1 cells but inhibits the viability of HGC27 and SGC7901 cells.Levobupivacaine (2 mM; 24, 48 or 72 h) enhances Erastin-induced inhibitory impact on HGC27 and SGC7901 cell viabilities; induces the levels of Fe2+, iron, and lipid ROS.Levobupivacaine (2 mM; 24 h) enhances the expression of miR-489-3p in HGC27 and SGC7901 cells, increases the levels of Fe2+ and iron. (In Vivo) :Levobupivacaine (40 μmol/kg; IP; once daily for 25 days) significantly inhibits SGC7901 cell growth, and enhances the lipid ROS accumulation.Levobupivacaine (5 or 36 mg/kg; IP; single dosage) increases the latency to partial seizures and prevents the occurrence of generalized seizures at low dosage; reduces the latency to N-methyl-d-aspartate (NMDA) -induced seizures and increased seizure severity at high dosage.
