Anecur®
Atracurium
25 & 50 mg Ampoule
Neuromuscular blockade for endotracheal intubation, surgery, or mechanical ventilation
Mechanism of Action:
Blocks neural transmission at the myoneural junction by binding with cholinergic receptor sites
Method of Administration:
IV: May be given undiluted as a bolus injection; do not administer IM (excessive tissue irritation). May also administer via continuous infusion; requires the use of an infusion pump. Use infusion solutions within 24 hours of preparation.
Notes
Contraindications:
Hypersensitivity to atracurium or any component of the formulation
Documentation of allergenic cross-reactivity for neuromuscular blockers is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Interactions:
Acetylcholinesterase Inhibitors: May diminish the neuromuscular-blocking effect of Neuromuscular-Blocking Agents (Nondepolarizing). Risk C: Monitor therapy
Calcium Channel Blockers: May enhance the neuromuscular-blocking effect of Neuromuscular-Blocking Agents (Nondepolarizing). Risk C: Monitor therapy
Inhalational Anesthetics: May enhance the neuromuscular-blocking effect of Neuromuscular-Blocking Agents (Nondepolarizing). Management: When initiating a non-depolarizing neuromuscular blocking agent (NMBA) in a patient receiving an inhalational anesthetic, initial NMBA doses should be reduced 15% to 25% and doses of continuous infusions should be reduced 30% to 60%. Risk D: Consider therapy modification
Pregnancy and Lactation:
Pregnancy Considerations
Small amounts of atracurium have been shown to cross the placenta when given to women during cesarean section.
Breast-Feeding Considerations
It is not known if atracurium is present in breast milk. It is recommended that caution be exercised when administering atracurium to breastfeeding women.
Warning and Precaution:
- Anaphylaxis: Severe anaphylactic reactions have been reported with atracurium use; some life-threatening and fatal. Appropriate emergency treatment (including epinephrine 1 mg/mL) should be immediately available during use. Use caution in patients with previous anaphylactic reactions to other neuromuscular blocking agents.
- Bradycardia: May be more common with atracurium than with other neuromuscular-blocking agents since it has no clinically-significant effects on heart rate to counteract the bradycardia produced by anesthetics.
Adverse Reactions:
1% to 10%: Cardiovascular: Flushing
<1%, postmarketing, and/or case reports: Bradycardia, bronchospasm, dyspnea, erythema, hypersensitivity reaction, hypotension, increased bronchial secretions, injection site reaction, laryngospasm, pruritus, seizure, tachycardia, urticaria, wheezing
Storage:
Store in 2-8º C
For single use only.
