Levobupivacaine (CHIROCAINE®) is a (S)-enantiomer of bupivacaine and it is related chemically and pharmacologically to the amino amide class of local anesthetics. Local anesthetics block the generation and the conduction of nerve impulses by increasing the threshold for electrical excitation in the nerve, by slowing propagation of the nerve impulse, and by reducing the rate of rise of the action potential. In general, the progression of anesthesia is related to the diameter, myelination, and conduction velocity of affected nerve fibers. Clinically, the order of loss of nerve function is as follows: 1) pain, 2) temperature, 3) touch, 4) proprioception and 5) skeletal muscle tone. Levobupivacaine (CHIROCAINE®) is a safer alternative for regional anesthesia than bupivacaine. It demonstrated less affinity and strength of depressant effects onto myocardial and central nervous vital centers in pharmacodynamic studies, and a superior pharmacokinetic profile.

Sample Use Guides
Surgical anaesthesia: epidural for surgery 10-20 mL (50-150 mg), epidural for cesarean section 20-30 mL (100-150 mg), peripheral nerve 30 mL or 0.4 mL/kg (75-150 mg or 1-2 mg/kg), ophthalmic 5-15 mL (37.5-112.5 mg), local infiltration 60 mL (150 mg).
Pain management: epidural for labor analgesia 10-20 mL (25-50 mg), epidural for post-operative pain 4-10 mL/h (5-25 mg/h).
Route of Administration:
Intravenous
The antagonist activity of levobupivacaine was tested at the human nicotinic acetylcholine (nACh), murine N-methyl-d-aspartate (NMDA), murine gamma-aminobutyric acid(A) (GABA(A)), and human 5-hydroxytryptamine(3A) (5-HT(3A)) receptors expressed in Xenopus oocytes using a 2-voltage clamp technique. The IC50 of levobupivacaine were 950 uM, 65 uM and 85 uM for NMDA, 5-HT(3A), and nACh receptors, respectively. Inhibition of the GABA(A) receptor required concentrations in excess of 10 mM.
