1. What is Beto 50 ZK and what is it used for

Metoprolol succinate (a selective beta-adrenolytic agent), the active substance in Beto 50 ZK, blocks certain beta-adrenergic receptors in the body, mainly located in the heart.
Beto 50 ZK is used:

• in the treatment of high blood pressure,
• in the treatment of chest pain (angina pectoris),
• in the treatment of heart rhythm disorders, including rapid heartbeat,
• in the prevention following the acute phase of myocardial infarction (heart attack),
• in cases of unpleasant sensation of irregular and (or) forceful heartbeat,
• in the prevention of migraine,
• in the treatment of heart failure.

In children and adolescents aged 6 to 18 years:

• in the treatment of high blood pressure (hypertension).

2. Information before using Beto 50 ZK

When not to use Beto 50 ZK

• if the patient is allergic to metoprolol succinate or to any of the other ingredients of this medicine (listed in section 6);
• if the patient is allergic to other beta-blocking agents;
• if the patient has severe asthma or severe wheezing attacks;
• if the patient is in shock due to serious heart problems;
• if the patient has conduction disorders in the heart (second- or third-degree atrioventricular block, high-grade sinoatrial block) or rhythm disorders (sick sinus syndrome), except in patients with a cardiac pacemaker;
• if the patient has serious circulatory problems (severe peripheral arterial disease);
• if the patient has untreated and uncontrolled heart failure (a condition usually causing breathlessness and swelling around the ankles);
• if the patient has a slow heart rate (<50 beats/min at rest before treatment);
• if the patient has very low blood pressure (systolic blood pressure <90 mmHg);
• if the patient has abnormally acidic blood (so-called metabolic acidosis);
• if the patient is taking any of the following medicines:
• monoamine oxidase inhibitors (MAOIs) – medicines used to treat depression;
• verapamil and diltiazem (medicines used to reduce blood pressure);
• antiarrhythmic medicines such as disopyramide (medicines used to treat irregular heartbeat).

Metoprolol must not be used in patients with chronic heart failure if:

• they have unstable, uncompensated heart failure (which may manifest as fluid accumulation in the lungs, poor circulation or low blood pressure);
• they are receiving or have recently received medicines that increase the force of heart contractions;
• they have a slow heart rate (less than 68 beats/min at rest before treatment);
• systolic blood pressure is persistently below 100 mmHg.

Warnings and precautions
Before starting treatment with Beto 50 ZK, consult a doctor or pharmacist if:

• the patient has asthma, bronchitis or lung function disorders;
• the patient has heart or circulatory disorders (e.g. slow heart rate); treatment with Beto 50 ZK may worsen these conditions;
• the patient has diabetes;
• the patient has thyroid disorders;
• the patient has severe liver disease;
• the patient has ever experienced a severe allergic reaction to any allergen;
• the patient has a rare form of angina pectoris called Prinzmetal's angina;
• the patient requires surgery under general anaesthesia. The anaesthetist must be informed about the use of Beto 50 ZK.
• the patient has a hormone-secreting tumour of the adrenal medulla (phaeochromocytoma): in such cases, prior and concomitant treatment with an alpha-adrenergic blocking agent is required;
• the patient has psoriasis.

Use of metoprolol may lead to positive results in anti-doping tests.
Children and adolescents
Experience with treatment in children under 6 years of age is limited.
The use of Beto 50 ZK is not recommended in children under 6 years of age.
Beto 50 ZK and other medicines
Tell your doctor or pharmacist about all medicines the patient is currently taking or has recently taken, as well as any medicines they plan to take.
Beto 50 ZK interacts with many other medicines.

• Medicines used to treat high blood pressure (including prazosin, clonidine, hydralazine, guanethidine, betanidine, reserpine, alpha-methyldopa and so-called calcium antagonists, e.g. verapamil, diltiazem or nifedipine).
• Other beta-blocking agents (including those contained in eye drops).
• Medicines affecting peripheral blood circulation (in fingers and toes), such as ergot alkaloids (which may be used to treat migraine).
• Medicines used to treat depression.
• Medicines used to treat other psychiatric disorders.
• Antiretroviral medicines used to treat AIDS and certain other diseases.
• Antihistamines (including over-the-counter medicines used to treat hay fever and other allergies, colds and other conditions).
• Medicines used to prevent malaria.
• Medicines used to treat fungal infections.
• Medicines affecting liver enzyme activity, e.g. rifampicin used to treat tuberculosis.
• Medicines used to treat heart disorders (including angina pectoris), such as amiodarone, digoxin, nitrates and antiarrhythmic agents.
• Other medicines that reduce heart rate: concomitant use of fingolimod (a medicine used in adults, children and adolescents to treat relapsing-remitting multiple sclerosis) with beta-blockers may enhance the heart rate-lowering effect during the first days of fingolimod treatment.
• Other medicines that lower blood pressure: concomitant use of aldesleukin (a synthetic protein used to treat metastatic kidney cancer) with beta-blockers may cause an enhanced blood pressure-lowering effect.
• Insulin and other antidiabetic medicines.
• Non-steroidal anti-inflammatory drugs (so-called NSAIDs), used to treat pain and inflammation.
• Local anaesthetics containing lidocaine.
• A medicine called dipyridamole, used to prevent blood clots.

Beto 50 ZK, food, drink and alcohol
Beto 50 ZK and alcohol may mutually enhance their sedative effects. Blood alcohol concentration may reach higher levels and decrease more slowly.
During treatment with Beto 50 ZK, alcohol consumption should be avoided.
Pregnancy, breastfeeding and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to become pregnant, she should consult a doctor or pharmacist before using this medicine.
Pregnancy
Beto 50 ZK may be used during pregnancy only if clearly indicated and after careful evaluation by the doctor of the benefit-risk ratio. There is evidence that metoprolol reduces blood flow in the placenta, which may lead to disturbances in fetal development. Treatment with Beto 50 ZK should be discontinued 48 to 72 hours before the expected delivery date. If this is not possible, the newborn should be closely monitored by the doctor for 48 to 72 hours after birth.
Breastfeeding
Beto 50 ZK passes into breast milk.
Metoprolol succinate should not be taken during breastfeeding unless absolutely necessary. Although adverse effects are unlikely when recommended doses are used, the breastfed infant should be carefully monitored for possible drug-related symptoms (e.g. the doctor will monitor heart function).
Driving and operating machinery
During treatment with Beto 50 ZK, dizziness or fatigue may occur. These symptoms may affect reaction speed to an extent that impairs the ability to drive, operate machinery or work in potentially hazardous conditions. These symptoms may be especially pronounced when alcohol is consumed concurrently or when switching from one medicine to another.
Beto 50 ZK contains glucose, monohydrate lactose and sucrose (sugar)
If the patient has previously been diagnosed with intolerance to certain sugars, they should consult a doctor before taking Beto 50 ZK.

3. How to use Beto 50 ZK

This medicine should always be used as directed by the physician. In case of doubt, consult your doctor or pharmacist.

The following products are available on the market: Beto 25 ZK (23.75 mg), Beto 50 ZK (47.5 mg), Beto 100 ZK (95 mg), Beto 150 ZK (142.5 mg), Beto 200 ZK (190 mg).

Your doctor will inform you how many tablets to take and when. The prescribed dose depends on the type and severity of the disease.

If the doctor has not advised otherwise, the usual dosage is as follows:

High blood pressure (hypertension)

• Patients with mild to moderate hypertension should take 47.5 mg of metoprolol succinate once daily.
• If necessary, the doctor may increase the dose to 95–190 mg of metoprolol succinate once daily, or add another antihypertensive medicine.

Chest pain (angina pectoris)

• 95–190 mg of metoprolol succinate once daily.
• If necessary, the doctor may add another medicine used in the treatment of ischemic heart disease.

Heart rhythm disorders, including rapid heartbeat (arrhythmias)

• 95–190 mg of metoprolol succinate once daily.

Treatment after myocardial infarction

• 190 mg of metoprolol succinate once daily.

Unpleasant sensation of irregular and/or forceful heartbeats (palpitations)

• 95 mg of metoprolol succinate once daily.
• If necessary, the doctor may increase the dose to 190 mg of metoprolol succinate once daily.

Prevention of migraine

• 95–190 mg of metoprolol succinate once daily.

Heart muscle weakness (heart failure)

Before starting treatment for heart muscle weakness, the patient's condition must first be stabilized with medicines commonly used in heart failure therapy. The dose of Beto 50 ZK is then individually adjusted for each patient.

• The recommended initial dose during the first week for patients with heart muscle weakness (classified as NYHA class III–IV heart failure) is 11.88 mg of metoprolol succinate once daily. The doctor may increase the dose in the second week to 23.75 mg of metoprolol succinate once daily.
• The recommended initial dose during the first 2 weeks for patients with heart muscle weakness (classified as NYHA class II heart failure) is 23.75 mg of metoprolol succinate once daily.
• Subsequently, the doctor will double the dose. The dose may be doubled every two weeks until reaching 190 mg of metoprolol succinate once daily, or the highest dose tolerated by the patient.
• The recommended dose for long-term maintenance therapy is 190 mg of metoprolol succinate once daily, or the highest dose tolerated by the patient.

Use in children and adolescents

High blood pressure:

In children aged 6 years and older, the dose depends on body weight. The doctor will determine the appropriate dose for the patient.

The usual initial dose of metoprolol succinate is 0.48 mg/kg once daily, but not exceeding 47.5 mg. The dose should be adjusted to the nearest available tablet strength. The doctor may increase the dose up to 1.9 mg/kg body weight, depending on the blood pressure response. Doses higher than 190 mg daily have not been studied in children and adolescents.

Beto 50 ZK is not recommended for use in children under 6 years of age.

The duration of treatment is determined by the doctor.

If you feel that the effect of Beto 50 ZK is too strong or too weak, contact your doctor or pharmacist.

Elderly patients

No studies have been conducted in patients over 80 years of age, therefore the doctor will increase the dose particularly cautiously in such patients.

Beto 50 ZK is intended for oral administration.

Tablets should be taken once daily, preferably with breakfast. Tablets may be divided into equal doses. They may be swallowed whole or divided, but should not be chewed or crushed. Tablets should be taken with water (at least ½ glass).

Taking more than the recommended dose of Beto 50 ZK

Seek immediate medical advice from your doctor or go to the nearest hospital emergency department. Based on the severity of poisoning symptoms, the doctor will decide on the appropriate management.

Show the medicine packaging to the doctor so that it is clear which medicine has been taken and what treatment should be initiated.

Symptoms of overdose

Symptoms that may occur following overdose of Beto 50 ZK include: dangerously low blood pressure, severe disturbances in heart function, breathing difficulties, loss of consciousness (or even coma), seizures, nausea, vomiting, cyanosis (bluish or violet discoloration of the skin), and death.

The first symptoms of overdose may appear within 20 minutes to 2 hours after taking Beto 50 ZK, and the effects of a significant overdose may last for several days.

Treatment of overdose

The patient should be treated in a hospital, in an intensive care unit. Even patients who appear to be in relatively good condition after a minor overdose of metoprolol should be closely observed by a doctor for at least 4 hours to monitor for signs of poisoning.

Missing a dose of Beto 50 ZK

Do not take a double dose to make up for a missed dose. Continue treatment as directed by your doctor.

Stopping treatment with Beto 50 ZK

Before stopping or prematurely discontinuing treatment with Beto 50 ZK, consult your doctor.

Beto 50 ZK should not be discontinued abruptly, but the dose should be gradually reduced. Sudden discontinuation of beta-blockers may worsen symptoms of heart failure and increase the risk of myocardial infarction and sudden cardiac death.

If you have any further questions about the use of this medicine, consult your doctor or pharmacist.
