Atenolol/chlorthalidone, also known as co-tenidone, is a combination medication used to treat high blood pressure. [2] [3] It is made up of atenolol, a beta-blocker and chlortalidone, a diuretic. [4] It is not recommended as an initial treatment but may be used in those who are taking atenolol and chlortalidone individually. [5] It is taken by mouth. [2]
Common side effects include gastrointestinal upset and gout. [3] Serious side effects may include liver problems, pancreatitis, and psychosis. [3] Use is not recommended during pregnancy. [3] Use during breastfeeding may harm the baby. [2] Atenolol works by blocking β1-adrenergic receptors in the heart, thus decreasing the heart rate and workload. [3] Chlorthalidone works by increasing the amount of sodium lost by the kidneys. [2]
The combination was approved for medical use in the United States in 1984. [4] It is available as a generic medication. [3] In 2017, it was the 304th most commonly prescribed medication in the United States, with more than 1 million prescriptions. [6]
