Description

Tenormin (Atenolol). Dosage, Side Effects, Interactions

Tenormin (Atenolol) belongs to the active ingredient group of cardioselective beta1-adrenoceptor antagonists and is mainly used to treat high blood pressure, cardiac arrhythmias and cardiovascular disorders.

Atenolol is indicated for the treatment of:

  • Functional cardiovascular complaints (hyperkinetic cardiac syndrome, hypertonic regulatory disorders)
  • Chronic stable angina pectoris or unstable angina pectoris (if coexisting with tachycardia or hypertension)
  • Supraventricular arrhythmias: additional therapeutic measure in sinus tachycardia due to thyrotoxicosis or paroxysmal supraventricular tachycardia, atrial fibrillation and atrial flutter (in the case of insufficient response to high-dose therapy with cardioactive glycosides)
  • Ventricular arrhythmias , such as: ventricular extrasystoles if the extrasystoles are caused by increased sympathetic nervous system activity (exercise, induction phase of anesthesia, halothane anesthesia and administration of exogenous sympathomimetics) or ventricular tachycardias and ventricular fibrillation (only prophylactic, especially if the ventricular arrhythmias are caused by increased sympathetic nervous system activity will)
  • Arterial hypertension

How Tenormin (Atenolol) works

Atenolol belongs to the group of drugs known as cardioselective beta1-adrenoceptor antagonists, also known as beta- blockers . The blood pressure in the vascular system is regulated by various endogenous messenger substances such as the stress hormones adrenaline and noradrenaline. Atenolol blocks the effects of adrenaline and noradrenaline. This lowers blood pressure and relieves the heart.

Atenolol takes effect after a few hours at the earliest. The maximum effect is reached after days or weeks, which is why the dose should only be increased slowly.

Dosage of Tenormin (Atenolol)

The dosage of atenolol depends on the patient’s response and the respective indication. The following recommended doses can be used to determine the dose:

  • Functional cardiovascular problems (hyperkinetic cardiac syndrome, hypertonic regulatory disorders): 25 mg atenolol once daily
  • Chronic stable angina pectoris or unstable angina pectoris: 50-100 mg atenolol once daily
  • Supraventricular and ventricular arrhythmias : 50 mg atenolol or 100 mg atenolol once or twice daily
  • High blood pressure : initially 50 mg atenolol once daily; If necessary, the daily dose can be increased to 100 mg atenolol after a week.

Side effects of Tenormin (Atenolol)

The most common side effects include fatigue, nausea, vomiting and diarrhea.

 

Contraindication

Atenolol must not be used in:

  • Hypersensitivity to the active substance, other beta-blockers
  • manifest heart failure
  • shock
  • 2nd or 3rd degree AV block
  • Sinus Node Syndrome (Sick Sinus Syndrome)
  • sinoatrial block
  • Bradycardia (resting heart rate less than 50 beats per minute before the start of treatment)
  • Hypotension (systolic less than 90 mmHg)
  • acidosis
  • bronchial hyperreactivity (e.g. in bronchial asthma )
  • Late stages of peripheral circulatory disorders
  • Simultaneous administration of monoamine oxidase (MAO) inhibitors (exception: MAO-B inhibitors)
  • intravenous administration of calcium channel antagonists of the verapamil or diltiazem type or other antiarrhythmics (such as disopyramide ) in patients treated with atenolol

Pregnancy

Atenolol should be used with caution during pregnancy.

 

Lactation

Atenolol should be used with caution during breast-feeding. The active substance accumulates in breast milk, where it reaches a multiple of the maternal serum concentration. Although the amount of active substance ingested in milk is not likely to pose a risk to the infant, infants should be screened for signs of beta-blockade. There may be an increased risk of hypoglycaemia and bradycardia in newborns born to mothers treated with atenolol during childbirth or breast-feeding.

 

Driving ability

The use of atenolol can lead to individually different reactions to the ability to react, so that the ability to actively participate in road traffic, to operate machines or to work without a secure footing can be impaired.
