Pharmacological action

Cardioselective beta1-blocker without internal sympathomimetic activity. It has a hypotensive, antianginal and antiarrhythmic effect. Reduces the automatism of the sinus node, reduces heart rate, slows down AV-conduction, reduces contractility and excitability of the myocardium, reduces cardiac output, reduces myocardial oxygen demand.

Suppresses the stimulating effect of catecholamines on the heart during physical and psycho-emotional stress.

Causes a hypotensive effect that stabilizes by the end of the 2nd week of course use. With angina pectoris, metoprolol reduces the frequency and severity of seizures. Normalizes heart rate with supraventricular tachycardia and atrial fibrillation.

In case of myocardial infarction, it helps to limit the area of ​​ischemia of the heart muscle and reduces the risk of fatal arrhythmias, reduces the possibility of recurrence of myocardial infarction. When used in medium therapeutic doses, it has a less pronounced effect on the smooth muscles of the bronchi and peripheral arteries than non-selective beta-blockers.

In connection with the possible development in the newborn of bradycardia, arterial hypotension, hypoglycemia and respiratory arrest, metoprolol must be canceled 48-72 hours before the planned delivery date. After delivery, it is necessary to ensure strict monitoring of the condition of the newborn for 48-72 hours.

Overdose

Symptoms: severe sinus bradycardia, dizziness, AV blockade (up to the development of complete transverse blockage and cardiac arrest), marked decrease in blood pressure, fainting, arrhythmia / ventricular extrasystole, consciousness, coma, nausea, vomiting, cyanosis, hypoglycemia, convulsions. The first signs of overdose manifest themselves after 20 min -2h after taking the drug.

Treatment: gastric lavage and the prescription of adsorbing drugs, symptomatic therapy: in case of a pronounced decrease in blood pressure - the patient should be in the position of Trendelenburg in case of excessive decrease in blood pressure, bradycardia and heart failure - in / in the introduction with an interval of 2-5 minutes beta-adreno-stimulators - until the desired effect is achieved or in / in the introduction of 0.5- 2 mg atropine sulfate. In the absence of a positive effect - dopamine, dobutamine or norepinephrine. As a follow-up, transvenous intracardiac pacemakers can be installed. At bronchospasm it is necessary to enter in / in beta-adrenomimetics. In convulsions - slow in / in the introduction of diazepam. Hemodialysis is ineffective.
