Thiopental Increase HR,dpresa both HR and Respiratory Depression C/I in HTN and heart
disease
Potent Anesthetic and Weak Analgesic is Halothane
Amide Local Anesthetic have double “i”.
Esters are metabolized by plasma and tissue esteras
Amides are metabolized by liver amidases
All local Anesthetics except cocaine are Vasodilators
Nondepolarizing NM blockers are reversible with AchE Inhibitor
Nondepolarizing NM blockers are metabolized by Plasma Cholinesterases
Depolarizing NM Blockers are hydrolyzed by
Pseudo-cholinesterase
