PNS

Cholinesterase inhibitors

prevent the breakdown of ACH

reversible and irrversible

Posioning→ pesticides from farming

cholinesterase inhibitors typically used for MG

Neuromuscular blocking agents

block ACH on Nm receptors

surgery

muscle relaxation

there are two types of NMBA

nondepolarizing

depolarizing

binds tightly to the receptor

Adrenergic Agents

stop bleeding

nasal decongestion

elevation of bp

mydrasis

ADEs

HTN

necrosis

bradycardia

alpha adrenergic blocking agents

selective alpha block → Minipress

lowers BP

cen acting alpha 2 agonists

Catapress→ bp

drowsines

rebound

xerostomia

contridicted with pregnancy

Methyldopa watch out for hemolytic anemia and hepatotoxicity
