Source-derived summary

Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. Although used to treat high blood pressure, it does not seem to improve mortality in those with the condition. Other uses include the prevention of migraines and treatment of certain irregular heart beats. It is taken orally (by mouth) or by intravenous injection (injection into a vein). It can also be used with other blood pressure medications.

Common side effects include feeling tired, heart failure, dizziness, depression, and shortness of breath. Other serious side effects include bronchial spasm. Use is not recommended during pregnancy and alternative drugs are preferred when breastfeeding. It works by blocking β1-adrenergic receptors in the heart, thus decreasing heart rate, force of heart beats, and blood pressure.

Atenolol was patented in 1969 and approved for medical use in 1975.

Editorial analysis

Why this record matters

The phrase “beta blocker medication primarily used to treat high blood pressure” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 8, 2026. The linked authority identifier is Q411325. The Library of Congress control number is sh85009098. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1969 and 1975.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
