Patient summary

Atenolol at 25mg, 50mg and 100mg, listed for hypertension, angina pectoris and arrhythmia. A beta-1 selective blocker, so the lungs are largely spared.

Mechanism of action

Selective beta-1 receptor antagonist. It blocks adrenaline effects specifically on the heart, reducing heart rate and contractility, which helps lower blood pressure and oxygen demand.

Pregnancy and breastfeeding

Pregnancy: Consult your doctor regarding use. Breastfeeding: Confirm breastfeeding suitability with a qualified clinician or pharmacist before use.

What you will receive

Tenormin is the originator brand name, made by AstraZeneca. We use it here to identify the medicine only; we are not affiliated with AstraZeneca and do not ship the original Tenormin.

  • You receive a generic equivalent: the same active ingredient (Atenolol) at the same dose, mostly recognised branded generics from vetted manufacturers.
  • The exact brand supplied depends on what is in stock at the dispatching warehouse.
  • Inactive ingredients, tablet appearance and packaging can differ from the original brand; the active ingredient and dose are the same.
