Introduction
Myorelex (also known as Suxamethonium Chloride) is a depolarizing skeletal muscle relaxant used in surgeries and certain emergency medical treatments. It is a drug that is used to temporarily paralyze the muscles for a short time, usually for up to ten minutes. This temporary paralysis is helpful for medical procedures such as tracheal intubation, an emergency life-saving procedure used in life-threatening situations when oxygen is not being supplied to the patient's lungs.Uses For
Myorelex is used in life-threatening situations where intubation of the airway is necessary. It can also be used during certain medical procedures such as transitioning a patient to a breathing tube, evaluating possible muscle problems, abdominal surgeries, repairs on the diaphragm, and as an aid during organ transplant surgeries. It can also be used during childbirth to help facilitate the delivery of the baby and as an aid during certain urological procedures.Mechanism of Action
Myorelex blocks the release of acetylcholine, a neurotransmitter that helps nervous system signals reach the muscles in order to make them contract. When the release of this neurotransmitter is blocked, the muscles can’t contract, leading to the paralysis effect.How Long Does It Take to Work?
The effects of Myorelex can be felt quickly. Usually, it takes only a few seconds to become effective. Within about one minute, the muscular paralysis should be complete.Absorption
Myorelex is absorbed from the site of injection, where it is able to enter the bloodstream quickly. It is then distributed throughout the body.Route of Elimination
Most of the drug’s effects will wear off fairly quickly due to it being broken down by enzymes in the bloodstream. Only a small portion of the drug is eliminated from the body in urine.Dosage
The dosage of Myorelex depends on the patient's condition, their body size, the type of procedure that is being done, and the area of the body that the drug is being injected into. Generally, for adult patients the recommended dosage is 2 to 2.5 milligrams per kilogram of body weight. For pediatric patients, the recommended dosage is 10 to 50 milligrams per kilogram of body weight, depending on the age of the patient.Administration
Myorelex is generally administered intravenously or intramuscularly. The injection should be done slowly in order to ensure that the muscle paralysis is effective.Side Effect
Some common side effects of Myorelex include increased heart rate, muscle twitching, increased secretions, nausea, vomiting, and a feeling of extreme weakness. Serious adverse reactions include difficulty breathing, irregular heart rate, and changes in blood pressure.Toxicity
If too much of the drug is given, it can cause respiratory depression and can even lead to death. Due to the potential for toxicity, the dosage should be adjusted for patients with conditions such as muscular dystrophy or hyperkalemia.Precaution
Myorelex should only be administered under the supervision of a qualified healthcare professional. The patient should also be closely monitored during the administration of the drug and should be kept in the recovery room until the effects of the drug have worn off.Interaction
Myorelex may interact with other drugs, such as anticholinesterase drugs, anesthetics, beta-blockers, antibiotics, antacids, and anticonvulsants. It may also interact with certain natural health products such as fish oil and St. John's Wort.Disease Interaction
Myorelex may interact with certain diseases such as hyperkalemia, bradycardia, myopathies, asthma, and certain neurologic conditions. Patients with these conditions should be closely monitored during and after the administration of the drug.Drug Interaction
Myorelex may interact with other drugs, such as anticholinesterase drugs, anesthetics, beta-blockers, antibiotics, antacids, and anticonvulsants. It may also interact with certain natural health products such as fish oil and St. John’s Wort.Food Interactions
There are no known food interactions with Myorelex. It is not recommended to take any food or drink for at least an hour before administration of the drug.Pregnancy Use
Myorelex should be avoided during pregnancy, unless specifically prescribed by a healthcare professional. There have been reports of adverse fetal effects, including congenital abnormalities, when the drug has been used during pregnancy.LactationUse
Myorelex should be avoided while breastfeeding, as it may pass into breast milk and cause harm to a nursing infant.Acute Overdose
Acute overdose with Myorelex can be life-threatening. Symptoms of overdose include difficulty breathing, extremely fast heart rate, and changes in blood pressure. Treatment of overdose includes intubation, artificial respiration, and use of anticholinergic drugs.Contraindication
Myorelex should be used with caution in patients with certain conditions, such as epilepsy, myasthenia gravis, muscular dystrophy, hyperkalemia, and conditions that may cause increased sensitivity to the drug.Use Direction
Myorelex should only be administered by a trained healthcare professional. The drug should be injected slowly, through either an intravenous or intramuscular route, and the patient should be monitored closely until the effects of the drug have worn off.Storage Conditions
Myorelex should be stored in a dry, cool place at room temperature. It should be kept away from light and moisture.Volume of Distribution
Myorelex is rapidly distributed throughout the body when administered, with a volume of distribution of approximately 1.7 liters/kg.Half Life
The half-life of Myorelex is approximately 5 minutes after a single intravenous dose. This means that the drug is eliminated from the body within about 5 minutes after administration.Clearance
The clearance rate of Myorelex is around 11.5 ml/min/kg. This means that the drug is eliminated from the body quickly, usually within about five minutes after administration.Here you find in details version of Myorelex
