G Pancuronium Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? G Pancuronium is a brand name. Its generic name is Pancuronium.
G Pancuronium Introduction
G Pancuronium is a neuromuscular blocking agent classed as a non-depolarizing neuromuscular blocker. It is derived from the alkaloid "tubocurarine" and functions by competitively binding to acetylcholine receptors at neuromuscular junctions, preventing the usual release of acetylcholine which in normal circumstances produces a muscle contraction. This results in muscle paralysis.
Uses of G Pancuronium
G Pancuronium is used as a muscle relaxant during general anesthesia. It is also used for intubation, mechanical ventilation, surgical and post-operative procedures, and provides muscle relaxation to facilitate general surgery, diagnostic and therapeutic procedures. It also provides skeletal muscular strength for immobilization during procedures.
Mechanism of Action
G Pancuronium works by blocking the central nervous system's ability to communicate with the skeletal muscles. This prevents the transmission of nerve impulses that cause muscular contraction. G Pancuronium also decreases the release of neurotransmitters from the motor end plate, which is the site of connection of a nerve to a muscle, to further reduce muscle contractility. The drug binds to nicotinic acetylcholine (Ach) receptors which are found on skeletal muscle cells. It prevents Ach from occupying the receptor and transmitting a nerve impulse, resulting in paralysis.
How Long Does It Take to Work?
G Pancuronium typically requires 1 minute to 5 minutes to take effect and induce muscular paralysis. It has a relatively short duration of action (approximately 60 minutes) and should only be used to achieve temporary paralysis.
Absorption
G Pancuronium is administered intravenously. It is metabolized slowly in the body and is excreted mainly via the kidneys.
//This can depend on the patient, as different patients have different metabolic rates.Route of Elimination
G Pancuronium is primarily eliminated through urinary excretion, with about 68% of an administered dose being excreted in the urine, and about 23% in the feces.
Dosage
The usual dose of G Pancuronium is 0.075mg/kg (0.03-0.2mg/kg) intravenously for adults. The dose may be adjusted based on the patient's age, size and medical condition.
Administration
G Pancuronium is usually administered intravenously. It should be used cautiously in patients with impaired renal or hepatic function.
Side Effects
The most common side effects of G Pancuronium are abdominal pain, nausea, vomiting, headache, dizziness, lightheadedness, and bradycardia (slow heart rate). Other side effects include an increase in blood sugar levels, blurred vision, difficulty breathing, and increased body temperature.
Toxicity
G Pancuronium is generally not toxic. Overdose of the drug can result in prolonged paralysis, and rarely, death. It should be used with caution in patients with high sensitivity to muscle relaxants.
Precaution
G Pancuronium should be used with caution in patients with COPD, as it may worsen shortness of breath. It should also be used with caution in patients with cardiac arrhythmias, hypertension, renal or hepatic impairment, and myasthenia gravis, as these conditions may increase the risk of adverse effects.
Interaction
G Pancuronium may interact with certain medications, such as those used to treat hypertension and heart conditions, as well as certain antibiotics. Therefore, it is important to tell your doctor about all medications you are taking and any allergies you have before taking G Pancuronium.
Disease Interaction
G Pancuronium may interact with certain medical conditions, such as kidney or liver disease, myasthenia gravis, heart disease, or hypertension. It is important to tell your doctor about any medical conditions that may increase your risk of adverse effects.
Drug Interaction
G Pancuronium may interact with certain medications, such as certain antibiotics, calcium channel blockers, diuretics, and drugs used to treat hypertension or heart conditions. It is important to tell your doctor about all medications you are taking before taking pancuronium.
Food Interactions
There are no known food interactions with G Pancuronium.
Pregnancy Use
G Pancuronium should not be used during pregnancy. It may increase the risk of respiratory depression in the newborn baby.
Lactation Use
G Pancuronium should not be used during lactation. It may pass into breast milk and could affect the nursing infant.
Acute Overdose
An overdose of G Pancuronium can cause severe muscle relaxation, and in extreme cases, respiratory failure. Treatment of an overdose may include supportive measures such as airway management, oxygen supplementation, and vasopressors.
Contraindication
G Pancuronium should not be used in people who are hypersensitive to the drug. Additionally, it should not be used in patients with severe cardiac arrhythmias, coronary artery disease, or prostatic hypertrophy.
Use Direction
G Pancuronium should be administered intravenously. The dose and rate of administration should be adjusted based on the patient's age, size, medical condition, and response to the drug.
Storage Conditions
G Pancuronium should be stored at room temperature in a light-resistant container. It should also be kept away from heat and moisture.
Volume of Distribution
The volume of distribution (Vd) of G Pancuronium is approximately 5L/kg in adults.
Half-Life
The half-life of G Pancuronium is approximately 2-3 hours in adults. It is slightly longer in elderly patients and those with renal or hepatic impairment.
Clearance
The clearance of G Pancuronium is approximately 2.7L/min in adults.
