Atracurium Besylate Injection USP 50mg/5mL

Non-depolarizing Neuromuscular Blocking Agent Skeletal Muscle Relaxant Anesthetic Adjunct

Atracurium Besylate Injection USP 50mg/5mL is a non-depolarizing neuromuscular blocking agent used during surgical procedures and intensive care to produce skeletal muscle relaxation. It works by blocking neuromuscular transmission at the neuromuscular junction, preventing acetylcholine from activating muscle contraction. This medication is commonly used during general anesthesia to facilitate endotracheal intubation and provide muscle relaxation during surgery or mechanical ventilation. Atracurium is particularly valuable because it undergoes Hofmann elimination, a metabolism process independent of liver or kidney function, making it suitable for patients with organ impairment. Manufactured according to USP pharmaceutical standards, Atracurium Besylate Injection ensures high quality, sterility, and consistent therapeutic performance for hospital and surgical use.

Key Information

Active Ingredient Atracurium Besylate 10mg/mL

Dosage Form Injection

Pack Size 2.5mL / 5mL Ampoule

Storage 2°C – 8°C (Refrigerate)

Benefits

Reliable muscle relaxation during surgery

Facilitates safe endotracheal intubation

Suitable for patients with renal or hepatic impairment

Predictable metabolism through Hofmann elimination

Widely used in anesthesia and critical care

Usage Instructions

Administer only by trained healthcare professionals.

Given via intravenous injection or infusion.

Dosage depends on patient weight, medical condition, and duration of surgery.

Continuous monitoring of neuromuscular function and respiration is essential.

Mechanical ventilation support is required until normal muscle function returns.

Mechanism of Action

Atracurium is a competitive antagonist of acetylcholine at nicotinic receptors located at the neuromuscular junction.

Its action leads to:

Temporary skeletal muscle paralysis

Relaxation of muscles required for surgical procedures

Facilitation of airway management during anesthesia

The drug is metabolized through Hofmann elimination and ester hydrolysis, allowing predictable breakdown without relying heavily on liver or kidney function.

Indications

Atracurium Besylate Injection is indicated for:

Facilitation of endotracheal intubation

Providing skeletal muscle relaxation during surgery

Adjunct to general anesthesia

Maintenance of muscle relaxation during mechanical ventilation

Use in intensive care units (ICU) for ventilated patients

Side Effects

Common:

Temporary muscle weakness

Flushing or mild hypotension

Histamine release reactions

Precautions

Must be administered in a setting equipped for respiratory support and airway management

Monitor neuromuscular blockade and recovery

Use cautiously in patients with asthma or histamine sensitivity

Dose adjustments may be required in critically ill patients

Contraindications

Known hypersensitivity to atracurium or related neuromuscular blocking agents

Patients with severe allergic reactions to similar drugs

Use cautiously in patients with neuromuscular disorders

Frequently Asked Questions

Find answers to common questions about Atracurium Besylate Injection USP 50mg/5mL

1 What is Atracurium Besylate Injection used for?

It is used to relax skeletal muscles during surgery and facilitate intubation under general anesthesia.

2 Does Atracurium affect breathing?

Yes, it temporarily paralyzes respiratory muscles, so mechanical ventilation is required during its use.

3 Why is Atracurium preferred in some patients with organ impairment?

Because it is metabolized through Hofmann elimination, which does not depend heavily on liver or kidney function.

4 Who should administer Atracurium Injection?

It must be administered only by trained anesthesiologists or healthcare professionals in a hospital setting.
