Betablok
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. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. In 2022, it was the 63rd most commonly prescribed medication in the United States, with more than 10 million prescriptions.
