Clinical and pharmacological group: Beta1-blocker
Pharmaco-therapeutic group: Selective beta1-blocker
pharmachologic effect
Cardioselective beta1-blocker without intrinsic sympathomimetic activity. It has hypotensive, antianginal and antiarrhythmic effects. Reduces the automatism of the sinus node, reduces heart rate, slows down AV conduction, reduces myocardial contractility and excitability, decreases cardiac output, and reduces myocardial oxygen demand. Suppresses the stimulating effect of catecholamines on the heart during physical and psycho-emotional stress.
It causes a hypotensive effect, which stabilizes by the end of the 2nd week of course use. With exertional angina, metoprolol reduces the frequency and severity of attacks. Normalizes heart rate with supraventricular tachycardia and atrial fibrillation. In case of myocardial infarction, it helps to limit the zone of ischemia of the heart muscle and reduces the risk of developing fatal arrhythmias, reduces the possibility of recurrence of myocardial infarction. Prevents the development of migraines.
When used in moderate therapeutic doses, in contrast to non-selective beta-blockers, it has a less pronounced effect on organs containing ?2-adrenergic receptors (pancreas, skeletal muscles, smooth muscles of peripheral arteries, bronchi and uterus) and on carbohydrate metabolism. When taken for many years, it reduces the concentration of cholesterol in the blood. When used in high doses (more than 100 mg / day), it has a blocking effect on both subtypes of ?-adrenergic receptors.
Pharmacokinetics
After oral administration, metoprolol is rapidly and almost completely absorbed from the gastrointestinal tract, Cmax of the active substance in the blood plasma is reached after 1-2 hours. After absorption, metoprolol is largely subjected to the effect of the 'first pass' through the liver. Plasma protein binding is low, about 5-10%. Vd is 5.6 l / kg. It is quickly distributed in tissues, penetrates the BBB, the placental barrier. Excreted in breast milk. Metoprolol undergoes oxidative metabolism in the liver (mainly with the participation of the isoenzyme CYP2D6) with the formation of 3 main metabolites, none of which has a clinically significant beta-adrenergic blocking effect. T1 / 2 of metoprolol from plasma is 3-4 hours and does not change during the course of treatment. More than 95% of the dose taken is excreted by the kidneys, about 5% of the dose taken is excreted by the kidneys unchanged.
Indications
Arterial hypertension,
prevention of angina attacks,
heart rhythm disturbances (supraventricular tachycardia, extrasystole),
secondary prevention after myocardial infarction,
hyperkinetic cardiac syndrome (including hyperthyroidism, NCD).

Application during pregnancy and lactation
Use during pregnancy is possible only if the intended benefit to the mother outweighs the potential risk to the fetus. Metoprolol crosses the placental barrier. In connection with the possible development of bradycardia, arterial hypotension, hypoglycemia and respiratory arrest in a newborn, metoprolol should 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.
Excreted in breast milk. Use during breastfeeding is contraindicated.
Application for violations of liver function
Use with caution in patients with severely impaired liver function.
Application for impaired renal function
Use with caution in patients with severe renal impairment.
Application in children
Contraindicated for use in children and adolescents under the age of 18 years.
Use in elderly patients
In elderly patients, it is recommended to start treatment with a dose of 50 mg / day, because a sharp decrease in blood pressure or increasing bradycardia may be more pronounced.
special instructions
Use with caution in patients with chronic obstructive respiratory diseases, diabetes mellitus (especially with labile course), Raynaud's disease and obliterating peripheral arterial diseases, pheochromocytoma (should be used in combination with alpha-blockers), severe renal and liver dysfunction.
Against the background of treatment with metoprolol, it is possible to reduce the production of tear fluid, which is important for patients using contact lenses.
Completion of a long course of treatment with metoprolol should be carried out gradually (at least within 10 days) under the supervision of a physician.
The simultaneous use of metoprolol with MAO inhibitors is not recommended.
When combined therapy with clonidine, the latter should be discontinued a few days after discontinuation of metoprolol, in order to avoid a hypertensive crisis. With simultaneous use with hypoglycemic agents, correction of their dosage regimen is required.
A few days before anesthesia, it is necessary to stop taking metoprolol or choose an anesthesia drug with a minimal negative inotropic effect.
Influence on the ability to drive vehicles and mechanisms
In patients whose activities require increased attention, the question of using metoprolol on an outpatient basis should be resolved only after assessing the patient's individual response.
Drug interactions
With simultaneous use with antihypertensive drugs, diuretics, antiarrhythmic drugs, nitrates, there is a risk of severe arterial hypotension, bradycardia, AV blockade.
With simultaneous use with barbiturates, the metabolism of metoprolol is accelerated, which leads to a decrease in its effectiveness.
With simultaneous use with hypoglycemic agents, it is possible to enhance the action of hypoglycemic agents.
With simultaneous use with NSAIDs, it is possible to reduce the hypotensive effect of metoprolol.
With simultaneous use with opioid analgesics, the cardiodepressant effect is mutually enhanced.
With simultaneous use with peripheral muscle relaxants, neuromuscular blockade may increase.
With simultaneous use with agents for inhalation anesthesia, the risk of inhibition of myocardial function and the development of arterial hypotension increases.
With simultaneous use with oral contraceptives, hydralazine, ranitidine, cimetidine, the concentration of metoprolol in the blood plasma increases.
With simultaneous use with amiodarone, arterial hypotension, bradycardia, ventricular fibrillation, asystole are possible.
With simultaneous use with verapamil, the Cmax in the blood plasma and the AUC of metoprolol increase. The minute and stroke volume of the heart, pulse rate, arterial hypotension decrease. Perhaps the development of heart failure, dyspnea and sinus blockade.
