Neuromuscular Blocking Agents USES
various uses, including
1. Assisting with sedation during general
anesthesia
2. Control of seizures during electroconvulsive therapy
3. Suppression of gag reflex during
endotracheal intubation.
Classifications of Miscellaneous CNS medications
1. Neuromuscular blocking agents
2. Muscle relaxants and
4. antispasmodic agents
Neuromuscular Blocking Agents names
succinylcholine (Anectine) and vecuronium.
,Muscle relaxants and antispasmodic agents affect
both the central and peripheral nervous systems.
Muscle relaxants and antispasmodic agents uses
These agents are used for spasticity related to muscle injury, cerebral palsy, spinal cord injury,
and
multiple sclerosis.
Agents include diazepam (Valium), baclofen (Lioresal), and dantrolene (Dantrium).
Bethanechol (Urecholine) is
a muscarinic agonist, is used for urinary retention.
Oxybutynin (Ditropan)
a muscarinic antagonist, is used for neurogenic bladder.
Neuromuscular Blocking Agents meds
Depolarizing neuromuscular blockers: succinylcholine (Anectine)
Nondepolarizing neuromuscular blockers: pancuronium
, Neuromuscular Blocking Agents actions
Neuromuscular blocking agents block acetylcholine (ACh) at the neuromuscular junction,
resulting in muscle relaxation and hypotension. They do not cross the blood-brain barrier, so
complete paralysis can be achieved without loss of consciousness or decreased pain sensation
Succinylcholine
››Mimics ACh by binding with cholinergic receptors at the neuromuscular junction. This agent
fills the
cholinergic receptors, preventing ACh from binding with them, and causes sustained
depolarization of the muscle, resulting in muscle paralysis.
›› Short duration of action because of degradation by the plasma enzyme
pseudocholinesterase.
Pancuronium, atracurium, vecuronium
›› Block ACh from binding with cholinergic receptors at the motor end plate. Muscle paralysis
occurs because of inhibited nerve depolarization and skeletal muscle contraction.
›› Reversal agent: neostigmine (Prostigmin)
Neuromuscular Blocking Agents side effects
1. Respiratory arrest from paralyzed respiratory muscles.
2. Hypotension possible with atracurium
Succinylcholine Side effects
1. Low pseudocholinesterase activity can lead to
prolonged apnea.
