When using tablets in the middle dosage, there is an effect on the tone of the peripheral arteries. Hypotensive effect of Atenolol develops throughout the day. The development of a sustainable therapeutic effect (normalization of pressure) is observed after 14 days of regular medication.
Antianginal effects of the drug are due to the ability of the drug to reduce the excitability and myocardial oxygen demand. Taking pills helps to reduce the heart rate when the patient performs any physical activity or is at rest.
The use of Atenolol contributes to an increase in the survival of patients who have suffered a myocardial infarction. In this case, the use of the drug reduces the number of attacks of ventricular arrhythmias and angina pectoris.
Indications for use

- For elderly patients, a single dose is 25-50 mg per day and can be increased. At the same time, it is necessary to regularly monitor heart rate and blood pressure level.
All categories of patients are not recommended to exceed the daily dosage of more than 100 mg, because it does not increase the therapeutic effect of Atenolol, but increases the risk of unwanted adverse reactions.
In case of an overdose with Atenolol, the risk of such side effects increases: bradycardia, fainting, arrhythmias, manifestations of heart failure, the level of arterial pressure can sharply decrease. The patient may complain of difficulty breathing, the development of dizziness, convulsions . In this case, you must immediately call an ambulance.
As a treatment, wash the stomach, give the patient activated carbon or another drug that has an adsorbing effect.
- In the case of bronchospasm development, immediate use of the drug Salbutamol (inhalation or intravenous) is required.
- With the development of bradycardia, atropine is injected intravenously or a pacemaker is temporarily installed; with ventricular estrasystole requires the use of lidocaine.
- In the case of lowering blood pressure, the patient should be in a supine position at an angle of 45 degrees, and the pelvis should be above the level of the head (Trendelenburg position).
Contraindications to the use of the drug Atenolol are: the development of cardiogenic shock, sick sinus syndrome, acute or chronic heart failure (decompensation stage), cardiomegaly, angina pectoris, arterial hypotension, arthroverticular blockade of 2-3 degrees, less pulse than 40 beats per minute.
Atenolol is not used for lowering blood pressure, which occurs against the background of myocardial infarction, as well as in the event that the systolic blood pressure is less than 100 mm Hg.
The drug can not be used during lactation, patients younger than 18 years of age and in the case of the development of individual intolerance of the active ingredient.
The drug Atenolol is used with extreme caution in the period of childbirth, in the case of diabetes, hypokalemia, allergies, chronic obstructive pulmonary disease, chronic cardiac, renal and hepatic insufficiency, depression, psoriasis.
Atenolol can cause the development of such undesirable side effects:
- Signs of heart failure, the development of bradycardia, cold in the arms and legs.
- The development of dizziness, sleep disorders, decreased performance and concentration, depression, headache.
- Dry mouth, nausea, abnormal stool.
- The development of bronchospasms.
- Reduced sweating and libido, the development of hypoglycemia.

Interaction with other drug groups
In the event that intravenous administration of the drug Verapamil is required, this can be done not earlier than 2 days from the moment of taking the last tablet of Atenolol.
The simultaneous intake of atenolol and cardiac glycosides can trigger bradycardia.
Not recommended for simultaneous use with aminophylline due to the risk of reducing the pharmacological effect of both drugs.
Simultaneous use with antihypertensive drugs of other groups and nitrates may cause an increase in the antihypertensive effect.
Simultaneous use with verapamil increases the risk of cardiodepressive effects.
With simultaneous use with lidocaine increases the risk of toxic effects.
Atenolol is contraindicated to apply simultaneously with MAO inhibitors.
Against the background of the use of the drug Atenolol, systematic monitoring of blood pressure and heart rate indices is required.
The drug can reduce concentration, therefore, Atenolol should be used with extreme caution to people whose activities require increased concentration and control of transport mechanisms.
Atenolol can reduce the effectiveness of drugs from the group of nonsteroidal anti-inflammatory drugs, xanthine and ergotamine.
While taking Atenolol, the production of tear fluid is reduced, this should be taken into account for people who wear contact lenses.
Atenolol can mask the tachycardia that occurs on the background of hypoglycemia and increase the duration of the hypoglycemic response to insulin intake. Patients with diabetes should be especially careful when combining Atenolol with hypoglycemic drugs.
