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 →Citalopram Overview
Citalopram is a medication called a selective serotonin reuptake inhibitor (SSRI) used to treat major depressive disorder in adults. It works by helping to restore the balance of a natural substance called serotonin in the brain, which can improve mood and feelings of well-being.

Citalopram
The mechanism of action of citalopram is unclear, but is presumed to be related to potentiation of serotonergic activity in the central nervous system (CNS) resulting from its inhibition of CNS neuronal reuptake of serotonin (5-HT).
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…
Citalopram
Citalopram is indicated for the treatment of major depressive disorder (MDD) in adults [see Clinical Studies ] . Citalopram is a selective serotonin reuptake inhibitor (SSRI) indicated for the treatment of major depressive disorder (MDD) in adults .

Drug Interaction: Minor
Atenolol and citalopram are unlikely to have a significant pharmacokinetic interaction because atenolol is primarily renally cleared and citalopram has minimal CYP2D6 inhibition. However, both drugs can independently cause bradycardia, so an additive pharmacodynamic effect resulting in mild bradycardia is theoretically possible.
Mechanism: Atenolol is predominantly eliminated renally, bypassing hepatic cytochrome P450 metabolism. Citalopram is a weak inhibitor of CYP2D6, but this is largely irrelevant for atenolol's disposition. Both agents can cause a reduction in heart rate, leading to a potential additive pharmacodynamic effect.
