Atenolol Overview
Atenolol is a medication used to treat high blood pressure. It works by helping to relax blood vessels and slow down your heart rate, which lowers your blood pressure and reduces the risk of serious heart problems like strokes and heart attacks.
Full Atenolol guide →Fluoxetine Overview
Fluoxetine is a type of antidepressant medication called a selective serotonin reuptake inhibitor (SSRI). It is used to treat conditions like depression, obsessive-compulsive disorder (OCD), bulimia nervosa, and panic disorder by helping to restore the balance of a natural substance called serotonin in the brain.

Fluoxetine
Although the exact mechanism of fluoxetine is unknown, it is presumed to be linked to its inhibition of CNS neuronal uptake of serotonin.
Approved Uses (Indications)
Atenolol
INDICATIONS AND USAGE Hypertension Atenolol is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including atenolol. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise…

Drug Interaction: Minor
Atenolol is primarily renally cleared and its metabolism is minimally affected by CYP2D6 inhibition. Therefore, fluoxetine, a potent CYP2D6 inhibitor, is unlikely to cause a significant pharmacokinetic interaction leading to increased atenolol levels. However, both drugs can independently cause bradycardia, so additive pharmacodynamic effects are theoretically possible.
Mechanism: Fluoxetine is a potent inhibitor of CYP2D6. Atenolol is primarily eliminated renally and is not significantly metabolized by CYP2D6, thus its plasma levels are not expected to be significantly altered by fluoxetine. The potential for interaction is primarily pharmacodynamic, as both drugs can cause bradycardia.
