1. What is Bloxazoc and what is it used for

Metoprolol succinate 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 heart rate (decrease in heart frequency).
Bloxazoc is used in the treatment of:

  • high blood pressure (hypertension),
  • chest pain caused by insufficient oxygen supply to the heart (angina pectoris),
  • irregular heart rhythm (arrhythmia),
  • heart palpitations (awareness of heart action) due to non-organic (functional) heart disorders,
  • stable heart failure (with symptoms such as shortness of breath and swelling of the ankles), in combination with other heart failure medications.

Bloxazoc is used in the prevention of:

  • another heart attack or heart damage after a heart attack,
  • migraine.

Bloxazoc is used to treat high blood pressure in children and adolescents from 6 to 18 years old.

The 23.75 mg tablet can be divided into equal doses.
The dividing line on the 47.5 mg, 95 mg, and 190 mg tablets is only to facilitate breaking the tablet to make it easier to swallow, not to divide it into equal doses.

The tablets should be swallowed with water.

47.5-95 mg of metoprolol succinate (50-100 mg of metoprolol tartrate) once a day.

The recommended initial dose for high blood pressure is 0.48 mg/kg body weight of metoprolol succinate (0.5 mg/kg body weight of metoprolol tartrate) once a day (half a 23.75 mg tablet for a child weighing 25 kg). The doctor will adjust the dose to the nearest available tablet strength. In patients who do not respond to a dose of 0.5 mg/kg body weight of metoprolol tartrate, the doctor may increase the dose to 0.95 mg/kg body weight of metoprolol succinate (1.0 mg/kg body weight of metoprolol tartrate), but should not exceed a dose of 50 mg of metoprolol tartrate. In patients who do not respond to 1.0 mg/kg body weight of metoprolol tartrate, the doctor may increase the dose to 1.9 mg/kg body weight of metoprolol succinate (2 mg/kg body weight of metoprolol tartrate) once a day (one 47.5 mg tablet for a child weighing 25 kg). Doses greater than 190 mg of metoprolol succinate (200 mg of metoprolol tartrate) once a day have not been studied in children and adolescents.
