Atenolol/chlorthalidone, also known as co-tenidone, is a combination medication used to treat high blood pressure.[3][4] It is made up of atenolol, a beta-blocker and chlortalidone, a diuretic.[5] It is not recommended as an initial treatment but may be used in those who are taking atenolol and chlortalidone individually.[6] It is taken by mouth.[3]

Common side effects include gastrointestinal upset and gout.[4] Serious side effects may include liver problems, pancreatitis, and psychosis.[4] Use is not recommended during pregnancy.[4] Use during breastfeeding may harm the baby.[3] Atenolol works by blocking β1-adrenergic receptors in the heart, thus decreasing the heart rate and workload.[4] Chlorthalidone works by increasing the amount of sodium lost by the kidneys.[3]

The combination was approved for medical use in the United States in 1984.[5] It is available as a generic medication.[4] A month supply in the United Kingdom costs the NHS less than 2 £ as of 2019.[4] In the United States the wholesale cost of this amount is about US$12.30.[7] In 2017, it was the 295th most commonly prescribed medication in the United States, with more than one million prescriptions.[8][9]
