She asked a colleague, "What is the generic name for Norcuron?" When her coworker told her it was vecuronium, she removed the neuromuscularblocking agent from the cabinet and gave the patient an unknown quantity from the 10 mg vial.
USP is developing guidelines to prevent accidents with vecuronium and other neuromuscularblocking agents based on what's been reported to the USP Medication Errors Reporting Program.
In the third case, a physician wrote "Narcan 1 amp IV." An ICU nurse tried to obtain the drug from an automated dispensing device where drugs were listed by their generic names.
Drugs such as the neuromuscularblocking agents bind reversibly to the nicotinic receptors in the neuromuscular junction and are used routinely in anaesthesia.
Muscarinic acetylcholine receptors can be blocked by the drugs atropine and scopolamine.
An acetylcholine receptor (abbreviated AChR) is an integral membrane protein that responds to the binding of the neurotransmitter acetylcholine.
Pancuronium bromide is the second drug used in the lethal injection process and is a neuromuscularblocking agent.
In some states, the execution protocols list only two drugs for lethal injections—North Carolina (sodium thiopental and pancuronium bromide) and New Jersey (potassium chloride and sodium thiopental).
Only a licensed medical practitioner can obtain and use the drugs.
Succinylcholine is the only neuromuscularblocking agent currently available that has been demonstrated to be effective after intramuscular (IM) administration when emergency control of the airway is required and there is no IV access.
Following IM succinylcholine, onset of neuromuscular blockade takes approximately 2 to 5 minutes; the response in patients who are hypotensive or hypovolemic is unpredictable.
If succinylcholine therapy is contraindicated (history of malignant hyperthermia, muscular dystrophy, neuromuscular disease, neurologic denervation injury or crush injury), a nondepolarizing muscle relaxant is indicated.
Levy testified that sodium Pentothal, Pavulon, and sodium chloride have well-known effects: sodium Pentothal is an ultra-fast acting barbiturate that is used in general anesthesia; Pavulon is a neuromuscularblocking agent that prevents nerve impulses from contracting muscles; and potassium chloride is normally used to increase a patient’s potassium level.
Coe would not have regained consciousness and would not have experienced any pain or discomfort as a result of the three drugs.
Coe would not have regained consciousness and would not have experienced any pain or discomfort as a result of any of the three drugs.
Nondepolarizing neuromuscularblocking agents bind competitively to cholinergic receptors on the motor end-plate to antagonize the actions of acetylcholine, resulting in a block of neuromuscular transmission.
Another group of NMBAs is categorized as NONDEPOLARIZING drugs.
The NONDEPOLARIZING NMBAs act as competitive acetylcholine antagonists.
Succinylcholine, by its depolarizing mechanism of action, is associated with additional adverse effects.This lecture presents some important side effects of currently used neuromuscularblockingdrugs from a clinical point of view.
Succinylcholine was responsible for 39% of cases of anaphylaxis, vecuronium for 36%, atracurium for 14%, and pancuronium for 5%.
Succinylcholine is a potent trigger for malignant hyperthermia.
Succinylcholine has the briefest duration of action of all neuromuscularblockingdrugs, making it a drug of choice for such procedures as terminating laryngospasm, endotracheal intubation, and electroconvulsive shock therapy.
Children are not as sensitive to succinylcholine on a weight basis as adults and may require higher doses.
Succinylcholine has no effect on consciousness or pain.
Accelerated onset of non-depolarizing neuromuscularblockingdrugs: pancuronium, atracurium and vecuronium.
Although the time to maximum NMB following divided doses of pancuronium, atracurium or vecuronium is significantly longer than that for succinylcholine, divided dosing significantly decreases the time required to reach maximal NMB.
However, when the two doses of drug were separated by 5 min, only small, non-significant further decreases occurred in the time required to achieve maximum blockade.
Suxamethonium was introduced into clinical practice in 1951 after the description of its neuromuscularblocking action.
While the rapid onset of suxamethonium can be mimicked with large doses of non–depolarizing drugs (and even approached with rocuronium), it is the rapid recovery from suxamethonium that is unique and is vital if potential disaster is to be avoided in the emergency situation.
The compromise that seems to have been agreed includes a recommendation that the use of suxamethonium in children be reserved for emergency intubation or instances where immediate securing of the airway is necessary.
Cardiovascular: Hypotension, myocardial depression Gastrointestinal: Nausea, vomiting Respiratory: Respiratory depression/arrest Miscellaneous: Shivering Drug Interactions Excessive hypotension may occur when combined with antihypertensive drugs Potentiate action of nondepolarizing neuromuscularblocking agents Nephrotoxicity with isoniazid Dosage Minimum alveolar concentration (MAC), the concentration at which 50% of patients do not respond to surgical incision, is 1.2% for isoflurane.
The concentration at which amnesia and loss of awareness occur (MAC - awake) is 0.4%.
Hypoxemia-induced increase in ventilation is abolished at low isoflurane concentration.
Over the years, serious life-threatening medication errors have been reported with the misuse of neuromuscularblocking agents (also known as paralyzing agents).
There are no USP standards for these drugs, primarily because the data needed to develop the monograph have not been submitted by the manufacturers.
Examples include the USP injections: Succinylcholine Chloride, Tubocurarine Chloride, Atacurium Besylate, and Vecuronium Bromide.
Pancuronium enhanced the inhibition of NET induced by ketamine.

To investigate the mechanism of action of pancuronium on NET,
Inflammatory eye disease, acute-angle glaucoma, history of retinal detachment, ocular hypotension, asthma, epilepsy, parkinsonism, gangrene, diabetes, CV disease, GI or GU tract obstruction, spastic GI conditions, vasomotor instability, severe bradycardia or hypotension, recent MI, lactation, in those receiving choline esters or depolarizing neuromuscularblockingdrugs.
The drug is released from the ocular therapeutic system three times faster during the first few hours and then decreases (within 6 hr) to a rate of 20 or 40 mcg/hr for 1 week.
Nitrate: The ocular therapeutic system is placed in the cul-de-sac of the eye for release of pilocarpine.
ChE inhibitors have been used as components of nerve gases but also have significant medical application in the treatment of disorders such as glaucoma and myasthenia gravis as well as in terminating the effects of neuromuscularblocking agents such as atropine.
The anxiolytic drugs of the benzodiazepine family exert their soothing effects by potentiating the responses of GABA-A receptors to GABA binding.
receptors are present in the gastrointestinal tract and are related to vomiting.
