Brand: Tenormin, Atenix, Atendol, Aten
Atenolol is a beta-blocker, a type of medication that primarily affects the heart. It works by blocking the effects of the hormone epinephrine (adrenaline), leading to a slower heart rate and lower blood pressure. This makes it useful for treating conditions like hypertension (high blood pressure), angina (chest pain), and certain types of abnormal heart rhythms. It can also be used to improve survival after a heart attack.
Used to treat hypertension, angina, certain abnormal heart rhythms, and to improve survival after a heart attack.
Outcome:
Rebound hypertension
Mechanism:
Sudden withdrawal of clonidine can cause a surge in blood pressure, which can be exacerbated by beta-blockers.
Outcome:
Increased risk of hypotension
Mechanism:
Both atenolol and alcohol can lower blood pressure.
Outcome:
Reduced atenolol absorption
Mechanism:
Antacids can bind to atenolol in the gut.
Most likely new formulation: Extended-release formulation to improve patient compliance (Year 2025, 30% confidence).
Based on current usage trends and ongoing clinical trials, there is a low (5%) likelihood of any major regulatory changes for atenolol in the next 2 years.
