<p>Levobupivacaine is a long acting local anaesthetic of the amide type. It is the S-enantiomer of bupivacaine. It blocks nerve conduction in sensory and motor nerves mainly by interacting with voltage sensitive sodium channels on the cell membrane. It also interferes with impulse transmission and conduction in other tissues. Levobupivacaine is given as the hydrochloride for infiltration anaesthesia and regional nerve blocks including epidural block. It is contraindicated in obstetric paracervical block and IV regional anaesthesia (Bier&#39;s block). The 0.75% solution is also contraindicated for epidural blocks in obstetrics.</p>
