what are therapeutic action pharmacokinetics
contraindications adverse effects and drug-drug interactions and
indication of nondepolarizing and depolarization neuromuscular
blocker
Neuromuscular blockkers:
Therapeutc action:It works at the neuromuscular junction, it used
adjuctively to anesthesia to produce paralysis, the vocal card,
permit intubation and cause relaxation of skeletal muscles.
Pharmakokinetics action in class of agent influenced by age or
anesthesia agent, it alters the hepatpic or reanl diseases
excretion pattern, causes prolong the duration of neuromuscular
blockade.
contraindications: when there is a patient with sepsis, burns,
massive trauma, CNS infection, prolong bed rest, immobilization,
disuse atrophy, peripheral nerve injury, Gillian barrier syndrome
cause potential risk, and data condition.
Adverse effects: it causes hypotension, flushing, and
tachycardia.
Drug to drug interaction with antimicrobial agents and volatile
anesthetic agents affect the sensitivity of the motor and make
presynaptic nicotinic function, magnesium inhibits Ach release,
procainamide, and quinidine block nicotine receptors channels.
calcium antagonists interfere with neuromotor release and muscle
contractility. pheytonin and lithium decrease Ach release,
corticosteroid, and furosemide increase the transmitter,
ecothiopate, tacrine drugs depress cholinesterase activity.
Depolarizing neuromuscular agents depolarize the rapid onset of
action, shortest duration of action, used for an emergency
situation, and reliable for the incubating condition.
Nondepolarizing agent for short-acting action used to induce
anesthesia in intubation, promote skeletal muscle relaxation during
surgery and intubation.
