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

Metoprolol succinate (selective beta-adrenergic blocker), the active substance of Beto 50 ZK, blocks certain beta-adrenergic receptors in the body, mainly located in the heart.
Beto 50 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 attackafter an acute phase,
• in case of unpleasant sensation of irregular and (or) strong heartbeat,
• to prevent migraines,
• 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 50 ZK

When not to take 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-adrenergic blockers;
• if the patient has severe asthma or severe wheezing;
• if the patient is in shock due to severe heart disorders;
• if the patient has conduction disorders in the heart (second or third degree atrioventricular block, high degree sinoatrial block) or heart rhythm disorders (sick sinus syndrome) unless they have a pacemaker;

or heart rhythm disorders (sick sinus syndrome) unless they have a pacemaker;

• if the patient has severe circulatory disorders (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 min at rest before treatment);< li>
  • if the patient has very low blood pressure (systolic blood pressure <90 mmhg);< li>
  • if the patient has a more than usual acidic blood reaction (so-called metabolic acidosis);
• if the patient is taking any of the following medicines: o monoamine oxidase inhibitors (MAOIs) - medicines used to treat depression; o verapamil and diltiazem (medicines used to lower blood pressure); o antiarrhythmic drugs, such as disopyramide (medicines used to treat irregular heartbeat).

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 receiving drugs that increase the strength of heart contractions.
• they have a slow heart rate (less than 68 beats/min at rest before treatment).
• their systolic blood pressure is consistently below 100 mmHg.

Warnings and precautions

Before starting to take Beto 50 ZK, the patient should discuss it with their doctor or pharmacist if:

• the patient has asthma, bronchitis, or lung function disorders;
• the patient has heart function disorders (e.g., slow heart rate) or circulatory disorders (taking Beto 50 ZK may worsen their course);
• the patient has diabetes;
• the patient has thyroid function disorders;
• the patient has severe liver disease;
• the patient has had a severe allergic reaction to any allergen;
• the patient has a rare form of chest pain, so-called Prinzmetal's angina;
• the patient needs to undergo surgery that requires general anesthesia. The anesthesiologist should be informed about taking Beto 50 ZK.
• the patient has 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.
• the patient has psoriasis.

Taking metoprolol may cause positive results in anti-doping tests.

Children and adolescents

Experience with the treatment of children under 6 years old is limited.
Beto 50 ZK should not be used in children under 6 years old.

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 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-adrenergic blockers (also those contained in eye drops).

• Medicines that affect liver enzyme activity, 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 slow down 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 medicine used to treat kidney cancer with metastases to other organs) with beta blockers may cause enhanced blood pressure lowering effect.
• Insulin and other anti-diabetic medicines.

Beto 50 ZK with food, drinks, and alcohol

Beto 50 ZK and alcoholmay enhance each other's sedative effects. The blood alcohol concentration may reach higher values and decrease more slowly.
During treatment with Beto 50 ZK, alcohol should be avoided.

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 50 ZK can be used during pregnancy only if clearly necessary and after a careful assessment by the doctor of the expected benefits to the potential risk. There is evidence that metoprolol reduces blood flow in the placenta, which can lead to fetal development disorders. Treatment with Beto 50 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 50 ZK passes into breast milk.
Metoprolol should not be taken during breastfeeding if it is not 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 the drug's effects (e.g., the doctor will monitor heart rate).

Driving and using machines

During treatment with Beto 50 ZK, dizzinessor fatiguemay occur. These symptoms can 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 50 ZK contains glucose, lactose monohydrate, and sucrose (sugar)

If the patient has previously been diagnosed with intolerance to some sugars, they should contact their doctor before taking Beto 50 ZK.

• 95-190 mgof metoprolol succinate once a day.

Heart failure (heart failure)
Before starting treatment for heart failure, it is necessary to stabilize the patient's condition with medicines usually used to treat heart failure, and then adjust the dose of Beto 50 ZK individually for the patient.

• The recommended initial dose in the first weekfor patients with heart failure(classified as heart failure grade III-IVaccording to NYHA) is 11.88 mgof metoprolol succinate once a day.

The recommended initial dose in the first 2 weeksfor patients with heart failure(classified as heart failure grade IIaccording to NYHA) 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 old, 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 50 ZK should not be used in children under 6 years old.
The duration of treatment is determined by the doctor.
If the patient feels that the effect of Beto 50 ZK is too strong or too weak, they should contact their doctor or pharmacist.

dangerously low blood pressure, severe heart function disorders, breathing difficulties, loss of consciousness (or even coma), seizures, nausea, vomiting, cyanosis (blue or purple discoloration of the skin), and death.
Treatment of overdose
