Question

DEPOLARIZING AGENT MOA

PHASE 1 and 2

LEIGHTON DWIGHT OBILLOS · Accepted Answer

Phase I - causes the opening of Na 
channel which results to depolarization 
of the receptor (transient twitching of 
the muscle or fasciculation)

Phase II – continuous 
depolarization gives way to 
gradual repolarization as the Na 
channel closes or is blocked 
(flaccid paralysis)
