Q

Lidocaine is a local anaesthetic (means only a small part of the body is treated and patient is generally awake) medication that is used to block pain sensations in a wide variety of superficial and invasive procedures. Lidocaine is able to inhibit action potentials, therefore reducing the sensation of pain in the CNS. What is the mechanism of action of Lidocaine?

1 - enters cell, ionised, binds with K+ channels and keeps them closed
2 - enters cell, ionised, binds with Ca2+ channels and keeps them closed
3 - enters cell, ionised, binds with Na+ channels and keeps them closed
4 - enters cell, ionised, binds with Po+4 channels and keeps them closed

A

3 - enters cell, ionised, binds with Na+ channels and keeps them closed

  • passes into cells
  • low pH in cell ionises lidocaine so it cannot leave the cell
  • ionised lidocaine binds and closed Na+ channels
  • no action potential are possible
