Betalok: instructions for use, side effects, contraindications and differences from Betalok ZOK

In order to successfully treat cardiovascular diseases, medications belonging to the group of B1-adrenergic receptor blockers are used. These drugs provide cardiac effects, which are expressed in a decrease in the frequency and strength of heart contractions, elimination anxiety and pain in the chest, a decrease in myocardial oxygen demand and the elimination of a number of other pathological phenomena that arise in cardiovascular system. Each of these drugs has its own characteristics. One of these medicines is Betaloc.

The cardiac drug is very popular due to its effective action and inexpensive price. It is prescribed for the treatment of various cardiac and vascular pathologies. However, this medication, like any other medication, has contraindications for use, and in case of an overdose, the medication can cause serious side effects. Therefore, before starting treatment with Betaloc, the instructions for use should be carefully studied.

What is the effect of the drug

The active substance is represented by metoprolol tartrate. It refers to a selective beta-blocker that does not exhibit intrinsic sympathomimetic activity.

Metoprolol is characterized by a stabilizing effect on membrane structures and a protective function, which is expressed in the suppression of the action of catecholamines. These hormones cause excessive excitement of the heart, which leads to tachycardia, increased myocardial oxygen demand, chest pain, and the development of hypertension. Catecholamines are secreted by the adrenal glands during excessive nervous excitement, stress and high physical activity.

The tablets have a prolonged action. Regular intake of the drug provides a persistent decrease in blood pressure in hypertensive patients. In case of heart diseases, the drug weakens the symptoms of angina pectoris, tachycardia, heart failure, atrial fibrillation and other ailments. In case of vascular diseases, metoprolol prevents migraine attacks.

Thus, Betaloc has the following therapeutic effects:

• antianginal;
• hypotensive;
• antiarrhythmic.

At the first symptoms indicating myocardial infarction, metoprolol solution is administered intravenously. This significantly reduces the risk of developing a dangerous condition and death.

Treatment with a drug for a particular ailment differs. In order to take Betaloc correctly, the instructions for use contain information on the dosage for each disease.

Once in the body, the active substance is immediately absorbed in full. Metoprolol passes through the liver and then enters the bloodstream, but only half of it. When taken regularly, this figure rises to seventy percent. The amount of the active component in the blood is linearly dependent on the dose taken. Systemic bioavailability is improved if the tablets are taken with meals. The concentration of Betaloc in blood plasma does not change depending on age. The average half-life of a substance is 3-4 hours.

Metoprolol is oxidized in the liver to form oxidative metabolites. The drug is excreted in the urine.

You can buy Betalok at the pharmacy. The drug is sold in vials packed in cardboard boxes. One bottle contains one hundred round white tablets with a line and engraving A / mE. The dose of metoprololl tartrate in one tablet is 100 mg. In the box, along with the bottle containing Betaloc tablets, there is an instruction for use.

In addition to the tablet form, Betaloc is available in the form of a liquid (solution) for injection or infusion. One ampoule contains 5 mg of active substance. Five ampoules are packed in a cardboard box.

Betalok treatment is prescribed for the following pathological conditions:

• regular increase in blood pressure (hypertension);
• vascular disorders that provoke acute headache (migraines);
• a syndrome characterized by pain and discomfort behind the breastbone (angina pectoris);
• severe conditions that arise as a result of the transferred heart attack (for the prevention of recurrent attacks);
• uneven or frequent heartbeat (different types arrhythmias);
• hyperthyroidism.

What is the difference between Betalok and Betalok ZOK and how to take medicine for different pathologies

The basis of Betaloc ZOK is also metoprolol. In fact, this medicine is a more advanced version of the usual Betaloc medicine.

Its chemical formula is metoprolol succinate. It comes in tablet form. Unlike Betalok, Betalok ZOK tablets are oval in shape, and the engraving is made in the form of the letter A, located above the letter B.

Betaloc ZOK tablets have different dosages (25 mg, 50 mg, 100 mg) and packaging. The drug with a minimum dosage is packed in blisters of fourteen pieces, the rest are packed in plastic bottles of thirty pieces each.

Like its predecessor, Betaloc ZOK blocks the action of hormones that make the heart work more actively. This allows you to cope with tachyarrhythmia, irregular heartbeats, reduce the risk of myocardial infarction, and normalize blood pressure in hypertension. Therefore, this drug has the same indications for use as Betaloc.

Since the therapeutic effect of medicines is equivalent, patients often have questions about how Betaloc differs from Betaloc ZOK, and which one is better. The main difference is in the formulation of the drugs. More modern tablets are characterized by a slow release of the active substance. Since metoprolol quickly enters the bloodstream and the therapeutic effect does not last long, the usual Betaloc should be taken twice a day. Unlike Betalok, Betaloc ZOK must be taken once in the morning, and its therapeutic effect lasts until the next day.

How to take Betaloc (100 mg) for the treatment of various diseases

Betaloc treatment should be supervised by a cardiologist. Depending on the pathology, the doctor determines the course of therapy and dosage. Betaloc is usually divided into two doses, less often into three or four, Betaloc ZOK is taken in a single dose. The tablets are swallowed whole with water.

• For the treatment of angina pectoris, characterized by the appearance of chest pain after physical and psychoemotional stress, the medicine is taken twice a day, in a dose not exceeding two tablets. Other drugs that have antianginal effects are often included in the therapy program.
• For hypertension, tablets can be taken as monotherapy or in conjunction with another antihypertensive drug. The dosage of the drug per day is one, two tablets, divided into two doses. Long-term use of the drug significantly reduces blood pressure and reduces the risk of strokes.
• In case of cardiac arrhythmias, one tablet is sufficient. Usually Betaloc is included in the complex therapy along with antiarrhythmic drugs.
• For the prevention of migraine, a single dose of one Betalok tablet is recommended.
• As a maintenance therapy after a myocardial infarction, take one or two tablets per day, morning and evening.
• With hyperthyroidism, the drug is taken three or four times. You can take from 150 to 200 mg per day.

If hypotension occurs when taking Betalok, then the dosage is reduced. After a while, the dose is increased again and, if the pressure does not drop critically, then it is left for further treatment. The tablets must be taken daily without skipping treatment. In this case, blood pressure indicators should be periodically determined.

Currently, the pharmacy network sells both drugs. What distinguishes Betalok from Betalok ZOK is the convenient use of the second drug (the effect lasts for a day) and less pronounced side effects of Betaloc ZOK, which is achieved due to the slow release of the active substances. Therefore, doctors most often recommend buying a more modern medicine.

Betalok ZOK: side effects and contraindications to treatment

Before prescribing Betaloc, the doctor identifies contraindications for taking the drug. It should not be taken by persons under the age of eighteen. Caution should be given to people who have severe liver and kidney pathologies, diabetes mellitus, chronic obstructive pulmonary disease, bronchial asthma.

When it is impossible to prescribe Betaloc (contraindications to treatment):

• with a sharp decrease in myocardial contractility;
• if blood pressure indicators are significantly reduced;
• with individual intolerance and hypersensitivity to metoprolol;
• with pathologies of the sinus node;
• if there are acute or chronic disorders of the heart in the stage of decompensation;
• in the acute stage of myocardial infarction;
• if atrioventricular block of the second and third degree is observed;
• with significant circulatory disorders in the peripheral vessels;
• with severe sinus bradycardia.

Side effects

The drug is well tolerated. If side effects occur when taking Betaloc ZOK, then such effects are usually mild and reversible. Conditions such as fatigue, dizziness, depression, headache, and nausea are possible. Sometimes there is a rash on the skin, a person feels dry mouth, his ears ring, his limbs get cold, the membranes of the eyes are irritated and taste is disturbed.

Often, especially at the beginning of drug therapy, the pressure can drop below normal, but usually this normalizes by itself. From the side of the heart, bradycardia, impaired conduction of the heart, and heart failure may increase.

In order to avoid side effects during treatment with Betolok ZOK, the instructions for the drug and the recommendations of the attending physician should be strictly followed.

Overdose

If, when taking Betalok, contraindications were not taken into account or the dose of the drug was significantly exceeded, then severe pathological conditions may develop, up to a lethal outcome.

Most often, there is a sharp decrease in blood pressure, since the drug has an antihypertensive effect. A person develops nausea, vomiting, general weakness, up to loss of consciousness. This can manifest itself both against the background of a decrease in blood pressure, and due to a decrease in heart rate (bradycardia).

Among the more serious pathological conditions, there are depression and respiratory arrest, convulsions, impaired functioning of the kidneys and liver, the development of heart failure, and cardiogenic shock. A blood test reveals an elevated glucose level. This can lead to the development of hypoglycemia.

Betaloc ZOK and alcohol: drug compatibility and consequences

There are no special instructions for alcohol in the instructions for the beta-blocker. However, such treatment naturally implies the elimination or significant restriction of alcohol intake. If an overdose of the drug occurred against the background of alcohol consumption, then the pathological conditions develop faster, and the symptoms appear more acute.

In order to eliminate side effects, the patient's stomach is washed and symptomatic treatment is prescribed. If there is a cardiac arrest, then resuscitation is carried out.

Taking the drug during pregnancy and lactation

Betaloc, like most other drugs that are very active, are not prescribed for pregnant women and women who are breastfeeding. The fetus and baby may experience side effects such as bradycardia. If taking the drug is necessary, then before deciding on Betaloc treatment, the doctor carefully evaluates its benefits to the mother and the possible risk to the fetus.
