Atenolol instructions for use
Atenolol is a drug from the group of beta-blockers.
As an active ingredient is the substance atenolol. The drug is available in a dose of 50 and 100 mg.
Use of tablets Atenolol promotes the provision of antihypertensive, antiarrhythmic and antianginal effects.
When using tablets in an average dosage, an effect on the tone of the peripheral arteries is observed. The 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 effect of the drug is due to the ability of the drug to reduce the excitability and the need for myocardium in oxygen. The intake of tablets reduces the heart rate when the patient is performing any physical activity or is at rest.
The use of atenolol helps to increase the survival rate of patients who have suffered myocardial infarction. In this case, the use of the drug can reduce the number of attacks of ventricular arrhythmias and angina pectoris.
Indications for use
Indications for taking Atenolol Tablets are:
- Complex treatment of high blood pressure.
- Prophylaxis of an attack of angina pectoris.
- The drug is also used for violations of the heart rhythm: with sinus tachycardia, as prevention of supraventricular tachyarrhythmias and ventricular extrasystoles.
Method of administration, dose
Tablets should be used before the main meal. I take the drug inside with water.
In the treatment of high blood pressure, the initial dosage of the drug is 50 mg, I take the drug once a day. In order to achieve a persistent pharmacological effect, tablets should be used regularly for 7-14 days.

Patients who have a history of coronary heart disease are recommended to take 50 mg of the drug per day.
With angina, the drug is taken from 50 mg per day and, as necessary, increased to 100 mg in one dose.
For patients who have a history of abnormal functioning of the kidneys and people of older age groups, it is necessary to adjust (reduce) the dosage individually:
- Patients who are on hemodialysis should take the medication at 25-50 mg per day. The drug should be taken in a hospital after dialysis and under the supervision of a doctor.
- For elderly patients, a single dose is 25-50 mg per day and can be increased. It is necessary to regularly monitor the heart rate and blood pressure level.
All patient categories are not recommended to exceed the daily dosage above 100 mg, since this does not increase the therapeutic effect of Atenolol, but increases the risk of unwanted adverse reactions.
In case of an overdose of Atenolol, the risk of such side effects increases: bradycardia, fainting, arrhythmias, manifestations of heart failure, blood pressure may drop drastically. The patient may complain of difficulty breathing, development of dizziness, convulsions . In this case, you need to immediately call an ambulance.
As a treatment, you should wash the stomach, give the patient an activated charcoal or another drug that has an adsorbent effect.
- In the case of bronchospasm, immediate use of Salbutamol (inhalation or intravenous) is required.
- With the development of bradycardia intravenously injected atropine or temporarily set the pacemaker; When ventricular estrasystole requires the use of lidocaine.
- In case of lowering blood pressure, the patient should lie in the supine position at an angle of 45 degrees, while the level of the pelvis should be above the head (Trendelenburg position).
Contraindications to the use of the drug Atenolol are: development of cardiogenic shock, sinus node weakness syndrome, acute or chronic heart failure (decompensation stage), cardiomegaly, angina pectoris, arterial hypotension, artiovertic blockade of 2-3 degrees, pulse beat less than 40 beats per minute.
Atenolol is not used with a decrease in blood pressure, which occurs against a background of myocardial infarction, and also if the systolic blood pressure index is less than 100 mmHg.
The drug can not be used during lactation, patients younger than 18 years of age and in case of development of an individual intolerance of the active component.
The drug Atenolol is used with extreme caution in the period of gestation, in the case of diabetes, hypokalemia, allergies, chronic obstructive pulmonary disease, chronic cardiac, renal and hepatic insufficiency, depression, psoriasis.
Atenolol can trigger the development of such undesirable side effects:
- Signs of heart failure, development of bradycardia, cold in the area of the hands and feet.
- Development of dizziness, sleep disorders, decreased efficiency and concentration of attention, depression, headache.
- Dry mouth, nausea, stool disorders.
- Development of bronchospasm.
- Decreased sweating and libido, the development of hypoglycemia.
- Allergic manifestations: itching, skin rash, redness.
If these reactions develop, you should consult your doctor. Dose adjustment, drug substitution or symptomatic treatment may be required.
Interaction with other drug groups
In the event that intravenous management of the drug Verapamil is required, this can be done no earlier than 2 days after the last Atenolol tablet was taken.
Simultaneous reception of Atenolol and cardiac glycosides can provoke a bradycardia.
It is not recommended simultaneous use with eufillin because of the risk of reducing the pharmacological effect of both drugs.
Simultaneous use with hypotensive drugs of other groups and nitrates can cause increased hypotensive effects.
Simultaneous use with verapamil increases the risk of cardiovascular depressions.
When used simultaneously with lidocaine, the risk of developing toxic effects increases.
Atenolol is contraindicated to be used simultaneously with MAO inhibitors.
Against the background of the use of the drug Atenolol requires systematic monitoring of blood pressure and heart rate.
The drug can reduce the concentration of attention, so Atenolol should be used with extreme caution to people whose activities require increased concentration and management of transport mechanisms.
Atenolol can reduce the effectiveness of drugs from the group of non-steroidal anti-inflammatory drugs, xanthine and ergotamine.
On the background of taking Atenolol, the production of tear fluid decreases, this should be taken into account by people who wear contact lenses.
Atenolol can mask a tachycardia that occurs against a background of hypoglycemia and increase the duration of a hypoglycemic reaction to the intake of insulin. Patients with diabetes should be especially careful when combining Atenolol with hypoglycemic drugs.
Patients with a history of ischemic heart disease should remember that abrupt withdrawal of a drug from a group of beta-blockers (Atenolol) can trigger complications. Abolition of the drug is carried out gradually and under the supervision of a doctor.
