Atenolol blocks the penetration of adrenaline and norepinephrine into the cells of the heart tissue, which leads to a decrease in the heart rate. In addition to the antiarrhythmic drug, it has hypotensive properties, that is, it lowers the upper and lower thresholds of blood pressure indicators.

According to the instructions, the regular use of this medication helps to completely normalize the heart rate and blood pressure by the second week of treatment. In addition, taking the drug improves coronary blood supply, contributing to the prevention of coronary artery disease.

After the course of Atenolol, there is a positive trend in the formation of a normal heart rate, arrhythmia disappears, and the saturation of the heart muscle with oxygen increases.

The patient may notice an improvement in cardiac activity not only during the rest period, but also during physical exertion.

The drug is taken orally, about 50% of the active substance Atenolol is absorbed by the gastric mucosa. The instructions for use describe that elderly people have an increased sensitivity to Atenolol by 10% of the standard values.

The maximum concentration of the substance in the blood plasma is observed 4 hours after ingestion. Poorly overcomes the barrier between the circulatory and nervous system. Atenolol easily and quickly passes into amniotic fluid and breast milk. Taking the drug does not affect the functioning of the liver and is excreted by the kidneys within 9 hours from the moment of administration.

On the first day of taking the medication, there is an increased vascular resistance, which decreases within 72 hours. The antianginal effect is expressed in a decrease in the number of heart beats per minute, the stabilization of blood pressure can be observed for 24 hours.

The effect on reducing the frequency of contractions of the heart muscle can be observed within an hour after the first dose of the drug Atenolol. Instructions for use prescribe the use of drugs for patients who have reached the age of 16 for the treatment of cardiac ischemia, angina pectoris, arterial hypertension.

It is used for prevention hypertensive crisis and suppression of senile tremor. The drug is prescribed to support the stable functioning of the heart after a heart attack. It can be used in combination with other drugs for the treatment of cardiac diseases.

Special care when taking is necessary for people taking digitalis for medicinal purposes, as well as people suffering from disorders of the digestive system of the body.

People with diabetes should carefully monitor the level of glucose in the circulatory system, since taking b-adrenergic receptor blockers can hide the signs of hypoglycemia and provoke the activity of drugs against diabetes.

In people suffering from hyperthyroidism, when taking medication, signs of tachycardia, which is caused by thyrotoxicosis, may disappear unnoticed.

If the appointment of the drug is necessary for patients suffering from broncho-obstructive syndrome, it is quite acceptable to take it in conjunction with b2-adrenergic agonists.

At ischemia: drug intervention starts with 50 mg per day. Under conditions of normal tolerance of the drug and the need to increase the dosage, use 100-200 mg per day.

The maximum allowable dosage for a mature person is 200 mg in 24 hours.

Disorder of the renal system should be the reason for special care in taking the medication, strictly under the supervision of a doctor:

• creatinine lumen 15-35 ml / minute - 50 mg per day;
• creatinine clearance less than 15 ml / minute - 50 mg every other day;
• against the background of hemodialysis - 50 mg after each procedure in a medical institution.

For elderly patients, the medication is prescribed at a time of 25 mg in conjunction with the control of heart rate and pressure.

Insulin, taken together with Atenolol, significantly enhances its hypoglycemic functions. With the simultaneous administration of the drug with antiglycemic agents, an increase in the hypotensive effect is observed. The simultaneous use of the drug with Verapamil or Diltiazem can provoke a mutual increase in the cardiodepressant effect.

Non-steroidal anti-inflammatory drugs and estrogens, taken together with Atenolol, exhibit a pronounced hypotensive effect. Reception with cardiac glycosides significantly increases the patient's risk of developing bradycardia, and also reveals atrioventricular patency disorders.

The combined use of the drug intravenously with Verapamil or Diltiazem can cause cardiac arrest in the patient. Nifedipine together with atenolol may cause a slight decrease in blood pressure.

It is highly not recommended to take the drug simultaneously with monoamine oxidase inhibitors. With this technique, the risk of developing a hypotensive effect is significantly increased. The interval in treatment with these drugs should be at least 2 weeks.

Allergens or extracts of allergens that are used to take samples from the skin, together with Atenolol, can provoke systemic allergic reactions of the body.

Means for inhalation anesthesia, used in conjunction with Atenolol, increase the risk of inhibition of the natural function of the myocardium, and arterial hypertension also develops. Joint intake of Cimetidine reduces metabolic activity in the body.

Iodine-containing medications for intravenous administration increase the risk of anaphylactic reactions.

Sedatives and various antidepressants inhibit the central nervous system when taken simultaneously with Atenolol.

The danger of a disorder of peripheral blood flow increases the simultaneous reception with non-hydrogenated alkaloids.

Atenolol: side effects and contraindications

Atenolol, the side effects of which occur as a result of taking the drug, is contraindicated in some cases.

In particular, it cannot be accepted:

• with individual hypersensitivity;
• with sinus bradycardia;

Even hallucinations and seizures are possible. The activity of the internal glands decreases, vision deteriorates, and tremors appear.

Not only the nervous system can react negatively to the components of Atenolol, but also cardiac-vascular. In this case, pains appear in the chest area, bradycardia, arrhythmia, atrioventricular blockade, heart failure, hypotension, thrombocytopenia, agranulocytosis develop.

The reaction of the digestive system to Atenolol is sometimes worrisome. Side effects are manifested by periodic urge to vomit, sometimes vomiting occurs, stool is disturbed, liver function does not change for the better, pain appears in the epigastric region.

Shortness of breath, bronchospasm, laryngospasm are possible negative reactions of the respiratory system. Side effects also include such reactions of the body as rash, itching, trophic disorders and characteristic changes in the skin, as well as urticaria, hyperhidrosis and myasthenia gravis (for its therapy, assign Mestinon).

In addition, libido and potency may decrease. A violation of heat exchange processes in the body is possible: a person's legs and arms are colder than the body. The activity of enzymes in the body changes. Perhaps an increase in the level of an enzyme such as bilirubin.

Withdrawal syndrome is a characteristic feature of Atenolol treatment. Reducing the dosage at the end of therapy or if another medication is prescribed to prevent the development of the syndrome.

If the dose is exceeded, one should expect the development of bradycardia, atrioventricular blockade, hypotension, the appearance of bronchospasm, and irregularities in the rhythm of breathing. Hypoglycemia, collapse, shock are possible. It is necessary to rinse the stomach, take adsorbents. In some cases, sympathomimetic agents, glycoside, diuretics, selective B-adrenomimetics are needed. In case of hypoglycemia, a glucose drip is placed. Dialysis is used in case of severe overdose.
