MOA for Versed:
Binds to the alpha/gamma subunits on GABA receptor
Enhances receptor’s affinity for GABA
Enhanced opening of Cl- channels
MOA for Fentanyl:
Mu Opioid Agonist
Increases K+ conductance, decreases Ca conductance (↓ cAMP)
MOA for Lidocaine:
Blocks VG Na+ channels and prevents AP conduction
MOA for Propofol
Modulates GABA through through GABA-A receptors
↑ Cl- conductance = hyperpolarization of postsynaptic membrane & neuron = sedative & hypnotic effects
MOA for Roc:
Blocks Ach release from pre-junctional sites
Competes for alpha subunits on post-junctional nAch R’s
prevents conformational change - inhibition of Na+ conduction - no impulses
MOA for Sucs:
Attaches to 1 or both alpha subunits on nACh Rs
Mimics Ach @ NMJ - causes depolarization of the post-junctional membrane
Post-junctional membrane cannot respond to subsequent release of Ach
MOA for Ketamine:
- NMDA antagonist: blocks Ca influx - ↓ release of glutamate
- Opioid receptor antagonist
MOA for Etomidate
Binds to GABA-A receptor & increases receptor’s affinity for GABA
MOA for Neo:
Alpha 1 Agonist
(mimics the alpha effects of Norepi but not as potent)
MOA for Ephedrine:
Non-catecholamine Sympathomimetic
Direct acting: alpha & beta agonist (non-selective)
Indirect: NE & endogenous catechol. release
MOA for Precedex
Stimulates a2 receptors & causes presynaptic inhibition (turns down SNS)
a2A: sedation, hypnosis, sympatholysis
a2B: Vasoconstriction, anti-shivering, analgesia, Ca-linked
a2C: learning, startle response

Onset: <1 min
