It has analgesic, antihypertensive and antiarrhythmic effects, reduces the automatism of the sinus node, inhibits AV ‑conduction, reduces myocardial inotropic function and heart rate. Reduces the number of angina attacks, reduces myocardial oxygen demand, increases exercise tolerance.
In myocardial infarction, it limits the zone of ischemia of the heart muscle and prevents heart rhythm disturbance.
Indications for use
AG; ischemic heart disease; stable or unstable angina; heart failure; heart rhythm disturbances; arrhythmias against the background of mitral valve prolapse; secondary prevention after myocardial infarction; functional disorders of cardiac activity, accompanied by tachycardia; hyperthyroidism; prevention of migraine attacks.
Dosage and administration
With hypertension and angina pectoris , the initial dose is 50 mg per day in 1 dose. The daily dose can be gradually increased to 100-200 mg in 1 dose. The drug can be used with other antihypertensive, antihypertensive and antianginal agents.

The drug can also be taken with food or on an empty stomach.
Side effects
Decreased heart rate, blood pressure. Violation of AV ‑conduction, symptoms of heart failure, depression. Fatigue, headache, dizziness, sleep disturbance. In many cases, these phenomena disappear on their own with a decrease in the dose of the drug.
Contraindications
Hypersensitivity to the drug; AV ‑block II-III degree, severe sinus bradycardia, arterial hypotension, acute decompensated heart failure, severe peripheral circulatory disorders, cardiogenic shock, BA, sick sinus syndrome.
Overdose
Symptoms . Severe hypotension, sinus bradycardia, AV ‑block, heart failure, cardiogenic shock, cardiac arrest, bronchospasm, impaired consciousness, coma, nausea, vomiting, and cyanosis. The simultaneous use of alcohol, drugs to lower blood pressure, quinidine or barbiturates can complicate the patient’s condition.
