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

Metoprolol succinate, the active substance of Beto ZK, blocks certain beta-adrenergic receptors in the body, mainly located in the heart.
Beto ZK is used:
to treat high blood pressure,
to treat chest pain,
to treat heart rhythm disorders, including accelerated heart rate,
for the prevention of heart attack,
in case of unpleasant sensation of irregular and (or) strong heartbeat,
to prevent migraine,
to treat heart failure.
In children and adolescents from 6 to 18 years old
to treat high blood pressure(hypertension).

2. Important information before taking Beto ZK

When not to take Beto ZK

if the patient is allergic to metoprolol succinate or any of the other ingredients of this medicine (listed in section 6);
if the patient is allergic to other beta-adrenergic blockers;
if the patient has severe asthma or severe wheezing;
if the patient is in shock due to severe heart problems;
if the patient has conduction disorders in the heart (second or third degree atrioventricular block or high degree sinoatrial block) or heart rhythm disorders (sick sinus syndrome) unless they have a pacemaker;
if the patient has severe circulatory problems (severe peripheral arterial disease);
if the patient has untreated and uncontrolled heart failure (a disease that usually causes shortness of breath and swelling of the ankles);
if the patient has a slow heart rate (<50 beats per minute at rest before treatment);
if the patient has very low blood pressure (systolic blood pressure <90 mmhg);
if the patient has a more acidic than usual blood reaction (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 lower blood pressure);
antiarrhythmic drugs, such as disopyramide (medicines used to treat irregular heart rhythm).
In patients with chronic heart failure, metoprolol should not be used if:
they have unstable, uncontrolled heart failure (which may manifest as fluid accumulation in the lungs, poor circulation, or low blood pressure).
they are constantly or periodically taking medicines that increase the strength of heart contractions.
they have a slow heart rate (less than 68 beats per minute at rest before treatment).
their systolic blood pressure is consistently below 100 mmHg.

Warnings and precautions

Before starting to take Beto ZK, the patient should discuss it with their doctor or pharmacist if:
they have asthma, bronchitis, or lung function disorders;
they have heart function disorders (e.g., slow heart rate) or circulatory problems (taking Beto ZK may worsen their course);
they have diabetes;
they have thyroid function disorders;
they have severe liver disease;
they have had a severe allergic reaction to any allergen in the past;
they have a rare form of angina pectoris, so-called Prinzmetal's angina;
they need to undergo surgery that requires general anesthesia. The anesthesiologist should be informed about taking Beto ZK.
they have a tumor of the adrenal gland that secretes hormones (pheochromocytoma): in such a case, it is necessary to use a medicine that blocks alpha-adrenergic receptors beforehand and at the same time.
they have psoriasis.
Taking metoprolol may result in positive doping test results.

Children and adolescents

Experience with the treatment of children under 6 years of age is limited.
Beto ZK should not be used in children under 6 years of age.

Beto ZK and other medicines

The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
Beto 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-adrenergic blockers (also those contained in eye drops).
Medicines that affect blood circulation in the extremities (in fingers and toes), such as ergot alkaloids (which can be used to treat migraine).
Medicines used to treat depression.
Medicines used to treat other mental disorders.
Antiretroviral medicines used to treat AIDS and some other diseases.
Antihistamines (also available without a prescription, 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 that affect the activity of liver enzymes, rifampicin used to treat tuberculosis.
Medicines used to treat heart function disorders (also angina pectoris), such as amiodarone, digoxin, nitrates, and antiarrhythmic drugs.
Other medicines that reduce heart rate: the 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 slowing effect in the first days after starting fingolimod.
Other medicines that lower blood pressure: the use of aldesleukin (a synthetic protein used to treat kidney cancer with metastases to other organs) with beta blockers may cause enhanced blood pressure lowering effect.
Insulin and other antidiabetic medicines.
Nonsteroidal anti-inflammatory drugs (NSAIDs), used to treat pain and inflammation.
Local anesthetics containing lidocaine.
A medicine called dipyridamole, which prevents blood clots.

Beto ZK with food, drink, and alcohol

Beto ZK and alcoholmay enhance each other's sedative effects. The concentration of alcohol in the blood may reach higher values and decrease more slowly.
During treatment with Beto ZK, the patient should avoid drinking alcohol.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
Pregnancy
Beto ZK can be used during pregnancy only if clearly necessary and after a careful assessment of the benefit-risk ratio by the doctor. There is evidence that metoprolol reduces blood flow in the placenta, which may lead to fetal development disorders. Treatment with Beto ZK should be discontinued 48 to 72 hours before the expected delivery date. If this is not possible, the doctor will closely monitor the newborn for 48 to 72 hours after birth.
Breastfeeding
Beto ZK passes into breast milk.
Metoprolol succinate should not be taken during breastfeeding unless absolutely necessary.
Although the occurrence of side effects is unlikely when using the recommended doses, the breastfed infant should be closely monitored for signs of metoprolol effects (e.g., the doctor will monitor the infant's heart rate).

Driving and using machines

During treatment with Beto ZK, dizzinessor fatiguemay occur. These symptoms may affect reaction speed to the extent that it impairs the ability to drive vehicles, operate machinery, and work in potentially hazardous conditions. Symptoms may occur especially when consuming alcohol, as well as when switching from one medicine to another.

Beto ZK contains glucose, lactose, and sucrose (sugar)

If the patient has been diagnosed with intolerance to some sugars, they should contact their doctor before taking Beto ZK.

3. How to take Beto ZK

This medicine should always be taken exactly as prescribed by the doctor. In case of doubts, consult a doctor or pharmacist.
The doctor will inform the patient about the dose and when to take it. The prescribed dose depends on the type and severity of the disease.

If the doctor has not prescribed otherwise, the following dosing is usually used:

Hypertension

• Patients with mild to moderate hypertensionshould take 47.5 mgof metoprolol succinate once a day.
• If necessary, the doctor may increase the dose to 95-190 mgof metoprolol succinate once a dayor use an additional medicine to lower blood pressure.

Angina pectoris

• 95-190 mgof metoprolol succinate once a day.
• If necessary, the doctor may use an additional medicine to treat coronary heart disease.

Heart rhythm disorders, including accelerated heart rate

• 95-190 mgof metoprolol succinate once a day.

Treatment after a heart attack

• 190 mgof metoprolol succinate once a day.

Unpleasant sensation of irregular and (or) strong heartbeat

• 95 mgof metoprolol succinate once a day.
• If necessary, the doctor may increase the dose to 190 mgof metoprolol succinate once a day.

Migraine prevention

• 95-190 mgof metoprolol succinate once a day.

Heart failure
Before starting treatment for heart failure, the patient's condition must be stabilized with medicines usually used to treat heart failure, and then the dose of Beto ZK should be adjusted individually for the patient.

• The recommended initial dose in the first weekfor patients with heart failure(classified as NYHA class III-IV) is 11.88 mgof metoprolol succinate once a day. The doctor may increase the dose in the second weekto 23.75 mgof metoprolol succinate once a day. The recommended initial dose in the first 2 weeksfor patients with heart failure(classified as NYHA class II) is 23.75 mgof metoprolol succinate once a day.
• Then the doctor will double the dose. The dose can be doubled every two weeksuntil a dose of 190 mgof metoprolol succinate once a dayis reached or the maximum dose tolerated by the patient.
• The recommended dose for long-term maintenance treatmentis 190 mgof metoprolol succinate once a dayor the maximum dose tolerated by the patient.

Use in children and adolescents
Hypertension:
In children over 6 years of age, the dose depends on body weight. The doctor will determine the dose suitable for the patient.
Usually, the initial dose of metoprolol succinate is 0.48 mg/kg body weight once a day, but not more than 47.5 mg. The dose is adjusted to the nearest tablet strength. The doctor may increase the dose to 1.9 mg/kg body weight, depending on the blood pressure response. In children and adolescents, doses above 190 mg per day have not been studied.
Beto ZK should not be used in children under 6 years of age.
The duration of treatment is determined by the doctor.
If the patient feels that the effect of Beto ZK is too strong or too weak, they should consult their doctor or pharmacist.

Elderly patients

No studies have been conducted in patients over 80 years old, so in such patients, the doctor will be particularly cautious when increasing the dose of Beto ZK.
Beto ZK is intended for oral administration.
Tablets should be taken once a day, preferably during breakfast. Tablets can be divided into equal doses. They can be swallowed whole or divided, but should not be crushed or chewed. Tablets should be taken with water (at least 1/2 glass).

Taking a higher than recommended dose of Beto ZK

The patient should immediately consult a doctor or go to the emergency department of the nearest hospital. Based on the severity of the symptoms of poisoning, the doctor will decide what action to take.
The packaging of the medicine should be shown to the doctor, so it is known what medicine was taken and what action to take.
Symptoms of overdose
Symptoms that may occur as a result of taking too much Beto ZK include: dangerously low blood pressure, severe heart problems, breathing difficulties, loss of consciousness (or even coma), seizures, nausea, vomiting, cyanosis (blue or purple discoloration of the skin), and death.
Treatment of overdose
The patient should be treated in a hospital, in the intensive care unit. Even patients who seem to be in good condition and have only slightly overdosed on metoprolol will be closely monitored by the doctor for at least 4 hours for signs of poisoning.

Missing a dose of Beto ZK

The patient should not take a double dose to make up for a missed dose, but continue treatment as prescribed by the doctor.

Stopping treatment with Beto ZK

Before stopping or prematurely discontinuing treatment with Beto ZK, the patient should consult their doctor.
Beto ZK should not be stopped abruptly, but the dose should be gradually reduced. Abrupt cessation of beta blockers may worsen heart failure symptoms and increase the risk of heart attack and sudden cardiac death.
In case of any further doubts about the use of this medicine, the patient should consult their doctor or pharmacist.
