Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain.[7] Although used to treat high blood pressure, it does not seem to improve mortality in those with the condition.[8][9] Other uses include the prevention of migraines and treatment of certain irregular heart beats.[7][10] It is taken orally (by mouth) or by intravenous injection (injection into a vein).[7][10] It can also be used with other blood pressure medications.[10]

Common side effects include feeling tired, heart failure, dizziness, depression, and shortness of breath.[7] Other serious side effects include bronchial spasm.[7] Use is not recommended during pregnancy[7] and alternative drugs are preferred when breastfeeding.[11] It works by blocking β1-adrenergic receptors in the heart, thus decreasing heart rate, force of heart beats, and blood pressure.[7]

Atenolol was patented in 1969 and approved for medical use in 1975.[12] It is on the World Health Organization's List of Essential Medicines.[13] It is available as a generic medication.[7] In 2022, it was the 63rd most commonly prescribed medication in the United States, with more than 10 million prescriptions.[14][15]
