Suxamethonium Chloride Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Suxamethonium Chloride is a brand name. Its generic name is suxamethonium chloride.

Suxamethonium Chloride Introduction

Suxamethonium chloride (also known as succinylcholine and sux) is a white crystalline substance used in medicine as a muscle relaxant and anesthetic. Suxamethonium chloride is a depolarizing neuromuscular blocking agent, which works through the breakdown of acetylcholine in nerve cells and increases the sensitivity of muscle cells to calcium. The drug is given as an intravenous injection. It is used to induce muscle relaxation during surgery and medical procedures, and to facilitate patient ventilation and intubation.

Uses for Suxamethonium Chloride

Suxamethonium chloride is used for short-term muscle relaxation in anesthesia, tracheal intubation and ventilator support, and to facilitate muscle relaxation during surgery, and abdominal and thoracic procedures. Suxamethonium chloride is also used to facilitate endotracheal intubation by providing muscle relaxation during anesthetic induction and intubation.

Mechanism of Action

When Suxamethonium Chloride is administered to the body, it will bind to the peripheral motor nerve endings in the nerve endings. This causes a massive release of acetylcholine from the motor nerve endings, leading to an overload of acetylcholine in the motor end plates and thus, causing depolarization of the nerve cells. Depolarization is achieved until the acetylcholine receptor becomes uncoupled from the ligand. This results in several effects, including fasciculations, paralysis and flaccid paralysis.

How Long Does it Take to Work?

Suxamethonium chloride begins to work in the body within seconds of being administered. The effects typically last for up to 3-5 minutes after the injection.

Absorption

Suxamethonium chloride is rapidly absorbed following intravenous injection, with peak concentration in the blood occurring within 3-8 seconds after injection. A single intravenous dose is usually effective for up to three minutes.

Route of Elimination

The drug is metabolized in the liver and excreted primarily in the urine. Suxamethonium chloride is rapidly eliminated from the body with a half-life of 10 to 30 minutes.

Dosage

The dose of Suxamethonium Chloride is typically 0.5 to 1.5 mg/kg, administered intravenously over 1 to 2 minutes. It is generally recommended as a single intravenous dose during anesthetic induction or intubation. It may also be administered through an endotracheal tube.

Administration

Suxamethonium chloride is usually administered intravenously as a bolus dose. It may also be administered via an endotracheal tube when endotracheal intubation is desired.

Side Effects

Side effects associated with Suxamethonium Chloride include nausea, vomiting, dizziness, sweating, flushing of the face, and difficulty in breathing. Additionally, excessive doses of Suxamethonium Chloride can cause skeletal muscle rigidity, excessive salivation, and bronchospasm. Rarely, the drug can cause anaphylaxis.
