How Bupivacaine works
Bupivacaine is a type of local anaesthetic.
It functions by blocking the conduction of nerve signals from the region of application to the brain. This action is achieved by binding to sodium channels on nerve cell membranes, which prevents sodium ions entry, subsequently inhibiting the generation of electrical impulses. As a result, numbness and pain relief occur in the specific area where Bupivacaine is administered.
