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
some 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 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 50 ZK

When not to take Beto 50 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, high degree atrioventricular block) 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 per minute 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 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);
• anti-arrhythmic medicines, 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 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 50 ZK, you should discuss it with your doctor or pharmacist,

• you have diabetes;
• you have thyroid function disorders;
• you have severe liver disease;
• you have ever had a severe allergic reaction to any allergen;
• you have a rare type of chest pain, so-called Prinzmetal's angina;
• you need to undergo surgery that requires general anesthesia. You should inform the anesthesiologist about taking Beto 50 ZK.

• 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-adrenergic blockers may cause enhanced blood pressure-lowering effect.
