Esmeron Introduction
Esmeron is a non-depolarizing neuromuscular blocking drug used to provide skeletal muscle relaxation during anesthesia and mechanical ventilation. This drug is typically used for surgical procedures in combination with general anesthetics and it improves patient safety during intubation.
Uses for Esmeron
Esmeron is generally used for initial tracheal intubation and maintenance of neuromuscular blockade for surgical interventions. It can be used to provide skeletal muscle relaxation during balanced general anesthesia and intensive care unit sedation and to facilitate fiberoptic endotracheal intubations.
Mechanism of Action
Esmeron works by blocking signals between the nervous system and the infected muscle causing skeletal muscle relaxation. This blocking action interrupts the release of acetylcholine, the chemical messenger that tells the muscle to contract. By preventing the release of this chemical, Esmeron makes certain musclesrelaxed and unable to respond to nerve signals.
How Long Does it Take to Work?
After administration of Esmeron, onset of neuromuscular blockade occurs in 1-2 minutes and peaks at 4-5 minutes. The duration of action of Esmeron is 30-60 minutes and it can be modified by adjusting the dose.
Absorption
Esmeron is administered intravenously and is almost completely absorbed from the injection site. Intravenous injection of Esmeron produces an immediate and predictable onset of action.
Route of Elimination
Esmeron is primarily eliminated through renal excretion. Cyclodextrin metabolites of Esmeron are found in the urine in concentrations above those in plasma.
Dosage
The standard intravenous dose of Esmeron is 0.6-1mg/kg body weight depending on the clinical situation. The usual adult dose of Esmeron is 0.6-2.4mg/kg body weight given over 10-20 seconds. The duration of action is 30-60 minutes and it can be modified by adjusting the dose.
Administration
Esmeron is usually administered intravenously as an injection, either by bolus injection or continuous infusion, depending on the clinical setting. The usual adult dose of Esmeron is 0.6-2.4mg/kg body weight given over 10-20 seconds.
Side Effects
Common side effects of Esmeron include hypotension, bradycardia, nausea, vomiting, headache, and myalgia. Other more serious adverse effects include arrhythmia, tachycardia, dyspnea, and urinary retention.
Toxicity
The potential toxicity of Esmeron is low when used in recommended doses. However, high doses or serum concentrations may cause neuromuscular blockade which can lead to respiratory failure and even death.
Precautions
It is important to monitor blood pressure, pulse, and respiratory rate before and after administration of Esmeron. Careful monitoring of vital signs is necessary in patients with a history of hypertension, arrhythmias, heart failure, or shock. Additionally, Esmeron should not be used in patients with known hypersensitivity to neuromuscular blocking agents.
Interactions
Esmeron may interact with other drugs that affect the neuromuscular system, such as anesthetics, anticholinergics, β-blockers, opioids, calcium channel blockers, certain antibiotics, and other drugs. It is important to inform the physician of any other medications that may be taken concomitantly.
Disease Interactions
Esmeron may interact with certain medical conditions such as myasthenia gravis, systemic lupus erythematosus, and hypothyroidism. Additionally, caution should be taken in elderly patients because of decreased muscle mass and aminopolysulfate metabolism.
Drug Interactions
Esmeron may interact with other drugs that affect the neuromuscular system, such as anesthetics, anticholinergics, β-blockers, opioids, calcium channel blockers, certain antibiotics, and other drugs. It is important to inform the physician of any other medications that may be taken concomitantly.
Food Interactions
Esmeron may interact with certain foods, such as milk and other dairy products, potentially decreasing its effectiveness. It is important to inform the physician of any food items that may be consumed concomitantly.
Pregnancy Use
Esmeron should be used during pregnancy only if the potential benefit justifies the potential risk to the foetus. Adequate studies in pregnant women have not been conducted, therefore it is recommended to consult the physician before taking this drug in pregnant women.
Lactation Use
Esmeron should not be administered to nursing mothers as there is not enough information regarding the effect of the drug on nursing infants. It is advised to consult the physician before taking this drug in breastfeeding women.
Acute Overdose
An acute overdose of Esmeron may lead to prolonged neuromuscular blockade, respiratory failure, hypotension, tachycardia, and arrhythmias. Management of overdose includes supportive and symptomatic treatment.
Contraindications
Esmeron should not be used in patients with known hypersensitivity to neuromuscular blocking agents, patients with a history of myasthenia gravis, or those suffering from conditions that decrease muscle mass, such as hypothyroidism. Additionally, Esmeron should not be administered to pregnant or breastfeeding women.
Use Direction
Esmeron should be administered intravenously, either by bolus injection or continuous infusion, depending on the clinical setting. The usual adult dose of Esmeron is 0.6-2.4mg/kg body weight given over 10-20 seconds.
Storage Condition
Esmeron should be stored in a cool, dry place, away from direct light and moisture. It should also be kept away from children and pets.
Volume of Distribution
The volume of distribution of Esmeron is 18-25L/kg and it is relatively independent of age and bodyweight.
Half Life
The half-life of Esmeron is approximately 2-3 hours, which is independent of age and body weight.
Clearance
The clearance of Esmeron is approximately 0.06-0.08L/kg/hour.
