This Information is Intended Only for Healthcare Professionals:

Atracurium-hameln Besilate 10 mg/ml Solution for Injection and Perfusion EFG

It is essential to read the entire contents of this guide before preparing this medicinal product.

Incompatibilities

Atracurium besilate is inactivated at high pH and should therefore not be mixed in the same syringe with thiopental or any other alkaline agent.

Consequently, the intravenous cannula should be flushed well between the perfusion of atracurium besilate and thiopental to avoid the formation of aggregates, which could cause an anaphylactoid reaction.

Reconstitution Instructions

Atracurium besilate is compatible with the following solutions for IV perfusion:

Diluted in the mentioned solutions to provide atracurium besilate concentrations of 0.5 mg/ml or higher, the resulting solutions remain stable in daylight for the mentioned periods, at temperatures up to 30°C.

Posology and Method of Administration

Solution for injection and perfusion

For single doses only. Any opened and unused solution should be discarded.

As with all neuromuscular blocking agents, it is recommended to monitor neuromuscular function during the administration of atracurium besilate, in order to establish individual dosing requirements.

• Use as an injection, in adults

Atracurium-hameln Besilate is administered by intravenous injection and should not be administered intramuscularly.

Relaxation

The recommended dose range for adults is 0.3 to 0.6 mg/kg of atracurium besilate (depending on the required duration of total neuromuscular blockade). This dose will provide adequate muscle relaxation for approximately 15 to 35 minutes.

Intubation

Endotracheal intubation can usually be performed within 90 seconds after intravenous injection of 0.5 to 0.6 mg/kg of atracurium besilate.

Repeat Dose

Total neuromuscular blockade can be prolonged by administering supplemental doses of 0.1 to 0.2 mg/kg of atracurium besilate. The first maintenance dose is usually required 20 to 45 minutes after the initial bolus injection; subsequent maintenance doses are typically administered at intervals of 15 to 25 minutes. However, the need for maintenance doses should be determined according to individual patient requirements and responses.

Successive supplemental dosing does not produce neuromuscular blocking effect accumulation.

As measured by the restoration of tetanic response to 95% of its normal intensity, spontaneous recovery occurs approximately 35 minutes after total neuromuscular blockade.

Once evidence of spontaneous recovery is present, the neuromuscular blockade produced by atracurium besilate can be rapidly reversed by administering standard doses of cholinesterase inhibitors, such as neostigmine or edrophonium, accompanied or preceded by atropine or glycopyrrolate, without evidence of recurarization.

• Use as a perfusion, in adults

Atracurium-hameln Besilate is a hypotonic solution and should therefore not be administered through the same perfusion system as a blood transfusion. In this case, atracurium besilate must be administered through a separate intravenous perfusion access.

After an initial bolus dose of 0.3 to 0.6 mg/kg, atracurium besilate can be administered as a continuous intravenous perfusion at a dose of 0.3 to 0.6 mg/kg/hour to maintain neuromuscular blockade during prolonged surgical procedures.

Atracurium-hameln Besilate can be administered as a continuous perfusion during cardiopulmonary bypass surgery, at the recommended perfusion doses.

Induced hypothermia, with a body temperature of 25° to 26°C, decreases the degradation rate of atracurium besilate. Consequently, under hypothermic conditions, total neuromuscular blockade can be maintained by administering approximately half of the original perfusion dose.

Atracurium-hameln can be diluted with a perfusion of the mentioned solutions.

• Application in children, in elderly patients, in patients with renal and/or hepatic insufficiency, with cardiovascular disease, with burns, and in patients treated in intensive care units (ICU)

Application in Children:

Calculated with respect to body weight, the dose in children over one month of age is similar to that of adults.

Neonates

The use of atracurium besilate is not recommended in neonates (children under one month of age), as there are insufficient data (see section 5.1). If neuromuscular blockade is required, even in newborns or premature neonates, the dose should be significantly reduced.

Application in Elderly Patients:

Atracurium besilate can be used at the standard dosage. However, it is recommended that the initial dose be at the lower end of the recommended range and that the medication be injected slowly.

Application in Patients with Renal and/or Hepatic Insufficiency:

Atracurium besilate can be used at the standard dosage in all levels of renal or hepatic insufficiency, including terminal stages.

Application in Patients with Cardiovascular Disease:

Patients with severe cardiovascular diseases may react more sensitively to transient hypotensive states. In such patients, atracurium besilate should be administered slowly and/or in fractionated doses over a period of 1-2 minutes.

Application in Patients with Burns:

As with other non-depolarizing neuromuscular blocking agents, patients who have suffered burns may develop resistance to its action. Depending on the time elapsed since the burn and the extent of the injuries, these patients may require higher doses of atracurium besilate.

Application in Patients Treated in Intensive Care Units (ICU):

When atracurium besilate needs to be administered for prolonged mechanical ventilation, the benefit-to-risk ratio of prolonged neuromuscular blockade should be considered.

After an optional initial bolus dose of 0.3 to 0.6 mg/kg, atracurium besilate can be used to maintain neuromuscular blockade by administering a continuous perfusion at a dose of 11 to 13 micrograms/kg/min (0.66-0.78 mg/kg/h). However, there is a wide interindividual variability in the required dosage in these patients. Some patients may require perfusion rates as low as 4.5 micrograms/kg/min (0.27 mg/kg/h) or as high as 29.5 micrograms/kg/min (1.77 mg/kg/h). Dosage requirements may vary over time. Therefore, the perfusion rate should be adjusted according to monitoring by peripheral nerve stimulation.

The rate at which spontaneous recovery from neuromuscular blockade occurs after atracurium besilate perfusion in ICU patients is independent of the duration of administration. Spontaneous recovery to a train-of-four ratio greater than 0.75 can be expected within approximately 60 minutes, with a range of 32-108 minutes observed in clinical studies (n=6).
