Contents of the pack and further information

1. What is Beloken 1 mg/ml and what is it used for

The active substance is metoprolol tartrate, which belongs to a group of medicines called beta-blockers. These medicines reduce the effect of stress hormones on some parts of the body. In this way, metoprolol is able to act on blood vessels and the heart, reducing blood pressure and heart rate.

This medicine is used in adults for the treatment of:

  • Heart rhythm disorders, especially rapid heartbeats (supraventricular tachycardia).
  • Treatment of patients who are hemodynamically stable with acute myocardial infarction defined or suspected. (Early intervention in the acute phase, prior to oral therapy).

2. What you need to know before you are given Beloken 1 mg/ml

Do not use Beloken 1 mg/ml

  • if you are allergic to metoprolol or any of the other ingredients of this medicine (listed in section 6).
  • if you have unstable heart failure, blockage (heart conduction disorder) or acute myocardial infarction.
  • if you have ever had very slow or irregular heartbeats or circulatory failure.

The use of Beloken 1 mg/ml is not recommended in children.

  • if you have signs/symptoms of low blood glucose levels (hypoglycemia).
  • if you have health problems such as asthma or breathing difficulties, circulatory disorders, heart problems, kidney or thyroid problems.
  • if during treatment with this medicine your heart rate slows down more and more.
  • if you have ever been told that you have pheochromocytoma (a tumor in the adrenal glands).
  • if you have very low blood pressure or severely impaired blood circulation.
  • if you have uncontrolled heart failure.

Using Beloken 1 mg/ml with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Some medicines may affect the action of other medicines.

In particular, inform your doctor if you are using any of the following medicines, as you may need to adjust the dose of one of the medicines:

  • Medicines used in heart and blood vessel treatments (such as digitalis/digoxin, calcium antagonists (verapamil or diltiazem), anti-arrhythmic agents (quinidine or amiodarone), ganglion-blocking agents, hydralazine, clonidine).
  • Other medicines such as monoamine oxidase inhibitors (MAOIs), inhaled anesthetics, antibiotics (rifampicin), anti-ulcer medicines (cimetidine), non-steroidal anti-inflammatory drugs (e.g., indomethacin, celecoxib), certain antidepressants and antipsychotics, antihistamines, other beta-blockers (e.g., eye drops, asthma medications), and other substances (e.g., alcohol, certain hormones, such as adrenaline), oral antidiabetics.

Consider that:

  • If you take clonidine and Beloken 1 mg/ml together and need to stop treatment with clonidine, you should stop taking metoprolol several days before stopping clonidine.
  • If you are taking oral antidiabetics, your doctor may need to adjust the dose.
  • The blood levels of this medicine may be increased if administered with anti-arrhythmic agents, antihistamines, antidepressants, antipsychotics, non-steroidal anti-inflammatory drugs, alcohol, or hydralazine.
  • The blood levels of this medicine may be decreased by rifampicin.
  • Administration of this medicine with anti-arrhythmic agents (quinidine or amiodarone) results in an increased effect of these medicines.
  • The effects of this medicine may be increased when administered with calcium antagonists (verapamil or diltiazem). Concomitant administration of these medicines should be avoided.
  • The effects of this medicine may be decreased when administered with adrenaline or indomethacin.

Taking Beloken 1 mg/ml with alcohol

Consuming alcohol may increase the levels of metoprolol in the blood, increasing the effect of the medicine. Avoid drinking alcohol with this medicine.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before you are given this medicine.

Beta-blockers, including metoprolol, may harm the fetus and cause premature birth.

Tell your doctor if you are breastfeeding, as Beloken 1 mg/ml may cause adverse effects in the breastfed baby, such as a slow heart rate.

Driving and using machines

Some patients may feel tired or dizzy when taking Beloken. If this happens, do not drive or operate tools or machines.

Beloken 1 mg/ml contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per 5 ml of solution for injection (one ampoule); this is essentially "sodium-free".

3. How Beloken 1 mg/ml will be given to you

Metoprolol intravenous injection is used in acute situations where rapid onset of action is necessary and should only be administered by expert personnel who can provide more information.

Your doctor will tell you how long you will need to be treated with this medicine. Do not stop treatment unless your doctor tells you to.

Treatment of patients who are hemodynamically stable with acute myocardial infarction defined or suspected. (Early intervention in the acute phase, prior to oral therapy):In the acute phase and as soon as possible after the patient arrives at the hospital, 5 mg of metoprolol will be administered intravenously as a bolus. A second and third injection of 5 mg will be repeated at 2-minute intervals, depending on the patient's hemodynamic status. (See "Before using Beloken 1 mg/ml").

Patients who have tolerated the total intravenous dose of 15 mg will be given 50 mg of metoprolol succinate or tartrate tablets 4 times a day for 48 hours, starting 15 minutes after the last injection.

Patients who do not tolerate the total intravenous dose of 15 mg will start oral treatment with caution, beginning with a lower dose.

Heart rhythm disorders, especially rapid heartbeats (supraventricular tachycardia):Initially up to 5 mg administered intravenously at a rate of 1-2 mg/minute. This dose may be repeated at 5-minute intervals until a satisfactory effect is achieved. A total dose of 10-15 mg usually achieves this effect.

Doses of 20 mg or more are unnecessary, as they do not provide greater therapeutic benefit.

Use in children and adolescents

It is not recommended due to limited experience with Beloken in children and adolescents.

Use in elderly patients

The dose of this medicine does not need to be adjusted in elderly patients.

If you think the action of this medicine is too strong or too weak, tell your doctor, healthcare professional, or pharmacist.

If you are given too much Beloken 1 mg/ml

If you think you have been given too much Beloken 1 mg/ml, consult your doctor or pharmacist immediately.

The first signs of overdose may appear between 20 minutes and 2 hours after administration of the medicine. If you experience any of these symptoms, contact your doctor, pharmacist, or the nearest hospital immediately.

If you take alcohol, antihypertensive drugs, quinidine, or sleeping pills (barbiturics) with metoprolol, the symptoms may worsen.

Treatment:

In case of severe hypotension and shock, plasma or plasma substitutes will be administered, and the patient will be kept under observation in the intensive care unit.

If the heart rate is excessively slow or irregular, atropine may be used intravenously and/or a pacemaker. If necessary, glucagon and/or dobutamine may also be administered, and the administration of calcium ions may be considered.

Bronchospasm can be reversed with a bronchodilator. For more information, see the Summary of Product Characteristics.
