In medicine, atenolol is a cardioselective adrenergic beta-antagonist that is "possessing properties and potency similar to propranolol, but without a negative inotropic effect."[1] Atenolol is hydrophilic[2]
History
Atenolol was developed by the Stuart Company which was a division of Imperial Chemical Industries (ICI). ICI was renamed Zeneca in 1992. Atenolol received approval in the United States August 19, 1981.[3] According to drugstore.com, 90 days of generic 50 mg pills costs $17.99 in January, 2009.
Metabolism
Atenolol is excreted unchanged in the kidneys. Elimination is dependent on the glomerular filtration rate. Atenolol is not metabolized in the liver by cytochrome P-450 2D6 allele.
Dosage
For healthy adults, the starting dose recommended by the manufacturer is 50 mg orally once daily and the maximum dose is 100 mg orally once daily. However, atenolol may require twice daily dosing[4]
Efficacy
Coronary heart disease
Heart failure
Although atenolol has not received indication in the United States for the treatment of heart failure, two cohort studies suggest that the beta-blockers atenolol and carvedilol may be more effect than metoprolol for the treatment of heart failure.[5][6]
Randomized controlled trials by one research group also suggest atenolol might benefit.[7][8]
Hypertension
