Pharmacodynamics and pharmacokinetics
Active active substance Betaloca reduces or eliminates the stimulating effect of catecholamines in stress and physical exertion, reduces myocardial contractility and cardiac output, reduces high blood pressure and heart rate. In addition, metoprolol reduces the need for myocardium in oxygen and prolongs the period of diastole.
The drug may slightly increase the level of TG, as well as slightly reduce the fraction of HDL and free fatty acids in blood plasma.
Tablets are characterized by sustained release of the active substance, so the concentration of the drug in the blood plasma remains unchanged, which provides a stable clinical effect for a day or more. The drug is better tolerated than its counterparts, the risk of unwanted side effects is markedly reduced.
Betaloc ZOK is absorbed completely. Absorption does not depend on the time of ingestion. The degree of connection with blood plasma proteins is 5-10%. The active substance is metabolized in the liver with the formation of three metabolites without beta-adrenoblocking activity.
About 95% of the drug is excreted in the urine, the remaining quantity is unchanged. The half-life period is 3-4 hours on average.

Thus, every 14 days the dose can be increased 2 times to reach a maximum dosage of 200 mg. However, the dose can not be increased until there is clear information about the patient's stable state. It is necessary to control the work of the kidneys.
Stable chronic heart failure of functional class II: in the beginning, a dose of 25 mg is prescribed. In the first 2 weeks, it can be increased to 50 mg per day, and then doubled every 14 days until a therapeutic effect is achieved. The maximum dosage is 200 mg per day.

Angina pectoris: 100-200 mg per day is prescribed (it can be combined with other agents for the treatment of angina pectoris).
Arrhythmia: it is prescribed 100-200 mg per day.
Impaired cardiac activity with palpitation: 100 mg per day (if necessary, dosage can be adjusted to 200 mg).
There are cases when at a dosage of 7.5 g the drug caused severe intoxication with a lethal outcome in an adult. At doses of 1.4 and 2.5 g, respectively, there was moderate and severe intoxication.
Overdose of this drug can lead to respiratory depression, atrioventricular blockade of I-III degree, lowering of arterial pressure, heart failure, bradycardia, asystole, weak peripheral perfusion, cardiogenic shock, apnea. In addition, Betaloc ZOK in elevated doses can cause impaired consciousness, tremor, excessive sweating and fatigue, bronchospasm, vomiting, hypoglycemia or hyperglycemia, impaired renal function, loss of consciousness, seizures, paresthesia, nausea, and esophageal spasm and hyperkalemia.
Initial signs of drug overdose will be noticeable in 20-120 minutes after administration.
As treatment, activated charcoal is prescribed, as well as gastric lavage if necessary.
Depending on the manifestations of an overdose, symptomatic treatment is performed. This may require intubation and adequate ventilation of the lungs, ECG monitoring, replenishment of bcc and glucose infusion. If necessary, enter atropine (before washing the stomach) intravenously 1-2 mg. When depression of the myocardium is administered dobutamine or dopamine. It is possible to use glucagon intravenously in a dosage of 50-150 μg per 1 kg of body weight. In some cases, adrenaline, terbutaline (for cupping bronchospasm), as well as an artificial pacemaker, helps. At an arrhythmia and an extensive ventricular complex the sodium solution is entered. Resuscitative measures may be necessary.
With the simultaneous use of the drug Betaloc ZOK and other beta-adrenoreceptor blockers, as well as MAO inhibitors and ganglion blockers, strict medical supervision is required.
