A long-acting amide local anaesthetic, widely used for spinal, epidural and regional nerve blocks.

Bupivacaine Hydrochloride is a long-acting amide local anaesthetic and one of the most widely used agents for spinal, epidural and regional nerve blocks. Like other amide anaesthetics it reversibly blocks nerve sodium channels to prevent the generation and conduction of nerve impulses in the target area.
Its hallmark is a long duration of action, which makes it a mainstay for surgical anaesthesia, obstetric procedures and prolonged peri-operative pain control. It is typically supplied as the monohydrate.
