1. What is Betaloc ZOK and what is it used for

Betaloc ZOK contains the active substance metoprolol, which belongs to a group of medicines called beta-blockers.
Metoprolol reduces the effect of stress hormones on the heart during physical and mental exertion.
This leads to a slowing of the heart rate (reduction of heart rate).
Betaloc ZOK is used in the treatment of:

• high blood pressure (hypertension) to lower blood pressure and reduce the risk of complications (such as heart attack or stroke) and death (including sudden death) from cardiovascular causes,
• chest pain (angina pectoris) caused by insufficient blood supply to the heart,
• irregular heart rhythm (arrhythmia), especially supraventricular tachycardia, ventricular extrasystoles, and atrial fibrillation, to slow down the heart rate,
• palpitations (awareness of heart function) due to non-organic (functional) heart disorders,
• chronic heart failure (with symptoms such as shortness of breath and swelling of the ankles), in combination with other heart failure medications, to increase survival, reduce hospitalization, improve left ventricular function, and improve quality of life.

Betaloc ZOK is used in the prevention of:

• another heart attack or sudden death after the acute phase of a heart attack,
• migraine attacks.

Betaloc ZOK is used to treat high blood pressure (hypertension) in children and adolescents from 6 to 18 years old.
