The classes and their drugs
- Local anestheticsBlocking voltage-gated sodium channels so nerves cannot fire impulses
- LidocaineBupivacaine
- Intravenous anestheticsSwitching off consciousness through brain GABA-A or NMDA receptors
- PropofolKetamine
- Inhaled anestheticsDepressing brain signaling, partly by enhancing GABA-A receptors
- Sevoflurane
- Non-depolarizing neuromuscular blockersCompeting with acetylcholine at muscle nicotinic receptors, causing paralysis
- RocuroniumAtracurium
- Depolarizing neuromuscular blockersDepolarizing the motor end-plate and keeping it depolarized, so muscle goes limp
- Suxamethonium
