Peripheral Nav blocker
Peripheral voltage-gated sodium channel blocker
Drugs with this mechanism (10)
- Articaine — Amide dental local anesthetic with fast onset.
- Bupivacaine — Long-acting local anesthetic; cardiotoxic if given intravascularly.
- Cocaine — Monoamine-reuptake-inhibiting local anesthetic; vasoconstriction preserves its ENT niche.
- Lidocaine — The prototypical amide local anesthetic; also a Class IB antiarrhythmic.
- Lidocaine injection — Injectable sodium-channel blocker for local anesthesia and ventricular arrhythmias.
- Mepivacaine — Amide local anesthetic with little vasodilation; useful without epinephrine.
- Prilocaine — Amide local anesthetic; methemoglobinemia at high dose.
- Procaine — The original ester local anesthetic (Novocaine); short-acting.
- Ropivacaine — Long-acting local anesthetic; less cardiotoxic than bupivacaine.
- Tetracaine — Potent, long-acting ester local anesthetic (topical/spinal).
