1. What Esmeron is and what it is used for

Esmeron is one of a group of medicines called muscle relaxants. Muscle relaxants are used during surgery, as part of the general anaesthetic.

Esmeron is used in adult patients as an auxiliary medicine in general anaesthesia to facilitate tracheal intubation during routine and rapid sequence induction of anaesthesia and to provide skeletal muscle relaxation during surgical procedures. Esmeron is also indicated as a supplementary medicine used in intensive care units (ICU) to facilitate intubation and mechanical ventilation.

Children and adolescents: Esmeron is used as an auxiliary medicine in general anaesthesia to facilitate tracheal intubation during routine anaesthesia and to provide skeletal muscle relaxation during surgical procedures in newborns, infants and adolescents (from birth to 17 years).

2. Important information before you use Esmeron

When not to use Esmeron

If you are allergic to rocuronium or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Information about your health may be important for the choice of the way Esmeron is given to you. You should tell your anaesthetist if you have ever had:

allergic reactions to muscle relaxants
kidney or liver problems
heart problems
swelling (e.g. swelling of the ankles)
nerve or muscle disease
a history of malignant hyperthermia (a rare condition where the body temperature rises rapidly)

Certain medical conditions may affect the way Esmeron works, such as:

low potassium levels in the blood
high magnesium levels in the blood
low calcium levels in the blood
low protein levels in the blood
dehydration
acidosis
high carbon dioxide levels in the blood (hypercapnia)
poor general health
obesity
burns

If you have any of these conditions, your doctor will decide on the dose of Esmeron that is right for you.

Children and elderly people

Esmeron can be used in children and elderly people, but your doctor should first assess your health.

Esmeron and other medicines

Tell your doctor about all the medicines you are taking, have recently taken or might take.

The following medicines may affect the way Esmeron works:

certain anaesthetics used during surgery

3. How to use Esmeron

Dose

Your doctor will decide on the dose of Esmeron that is right for you. Esmeron will be given to you before and/or during surgery. The usual dose is 0.6 mg/kg body weight of rocuronium bromide, which lasts for 30 to 40 minutes. During surgery, the effect of Esmeron will be monitored.

If necessary, a further dose of Esmeron may be given. The dose of Esmeron depends on many factors, including possible interactions with other medicines given at the same time, the length of the surgical procedure, your age and health.

Method and route of administration

Esmeron is not intended for self-administration by the patient. Esmeron is given by injection into a vein, as a single injection or as a continuous infusion.

Only a doctor or nurse is allowed to give you Esmeron.

Overdose

It is unlikely that you will be given too much Esmeron, as your doctor will be monitoring its effect. If you are given too much Esmeron, artificial respiration will be continued until you can breathe on your own again. The effect of Esmeron can be shortened by giving a medicine that reverses its effect.

Missed dose

This is not applicable.

4. Possible side effects

Like all medicines, Esmeron can cause side effects, although not everybody gets them.

Uncommon or rare side effects (affecting 0.01% to 1% of people) include:

increased heart rate (tachycardia)
low blood pressure (hypotension)
weakness or increased effect of Esmeron
pain at the injection site
prolonged muscle relaxation

Very rare side effects (affecting less than 0.01% of people) include:

allergic reactions, such as changes in blood pressure or heart rate and shock due to low blood volume
chest tightness caused by bronchospasm
skin disorders (e.g. angioedema, redness, rash or blisters)
muscle weakness or paralysis
prolonged muscle disorders, usually seen in critically ill patients (steroid myopathy), when Esmeron and corticosteroids are used together in intensive care units

Frequency not known (cannot be estimated from the available data):

severe allergic coronary artery spasm (Kounis syndrome) causing chest pain (angina) or heart attack (myocardial infarction)
pupil dilation (mydriasis) or fixed pupils that do not change size in response to light or other stimuli

Children and adolescents

Clinical studies in children and adolescents with rocuronium bromide (up to 1 mg/kg body weight) showed an increased heart rate in 1.4% of patients.

Reporting of side effects

If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet.

Information intended for healthcare professionals only:

For intravenous use only.

As with other neuromuscular blocking agents, Esmeron should only be administered by, or under the supervision of, experienced clinicians who are familiar with the use of these agents and with reversal agents.

The dose of Esmeron should be individualised for each patient.

During the dose-finding process, it is important to monitor the patient for the first signs of muscular blockade (e.g. fading of the adductor pollicis twitch response).

It is recommended that the monitoring of neuromuscular transmission should be continued to assess the degree of neuromuscular blockade and to adjust the dose of Esmeron accordingly.

Inhalational anaesthetics potentiate the neuromuscular blocking effect of rocuronium bromide. This potentiation is clinically relevant during the use of inhalational anaesthetics for longer than 1 hour.

The recommended dose of Esmeron for intubation and for providing skeletal muscle relaxation during surgery or in intensive care units is given below.

Surgery

Intubation

The standard intubating dose of Esmeron is 0.6 mg/kg body weight. Intubating conditions will be excellent in the majority of patients at 60 seconds.

Recovery from neuromuscular blockade

After administration of the intubating dose, the clinician should not expect a full recovery of neuromuscular transmission for 30 to 40 minutes.

When neuromuscular blockade is first detected, the dose of Esmeron is increased in increments of 0.1 to 0.2 mg/kg until the desired level of neuromuscular blockade is achieved.

Continuous infusion

Esmeron can be administered by continuous infusion to maintain neuromuscular blockade during extended surgical procedures or in an intensive care setting.

After the initial intubating dose, a continuous infusion of 0.3 to 0.6 mg/kg/h of Esmeron will normally be required to maintain adequate neuromuscular blockade.

During infusion, the rate of administration of Esmeron should be adjusted according to clinical need (e.g. to maintain at least 95% blockade of the adductor pollicis twitch response).

Once the infusion has been started, the rate of administration can be reduced to 0.3 to 0.4 mg/kg/h to maintain blockade.

Infusion rates may need to be increased in patients with hepatic or renal disease.

Paediatric population

Intubating dose

The intubating dose of Esmeron is 0.6 mg/kg body weight in children (from birth to 17 years).

Recovery from neuromuscular blockade

After administration of the intubating dose, the duration of action of Esmeron is longer in infants (28 days to 23 months) than in children (2 to 11 years).

Geriatric population

The standard intubating dose of Esmeron is 0.6 mg/kg body weight.

Patients with renal or hepatic impairment

No dose adjustment is required in patients with renal or hepatic impairment.

Obese patients

In obese patients, the dose of Esmeron should be based on ideal body weight.
