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.

Paroxetine Overview

Paroxetine is a prescription medication used to help women manage moderate to severe hot flashes and night sweats (vasomotor symptoms) associated with menopause. While it belongs to a class of drugs that can affect brain chemicals, this specific formulation works differently and is not used to treat mental health conditions.

How Each Drug Works

Paroxetine

Nonclinical studies have shown that paroxetine is an SSRI. Paroxetine capsules are not an estrogen, and its mechanism of action for the treatment of VMS is unknown.

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…

Paroxetine

Paroxetine Capsules are indicated for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause. Limitation of Use: Paroxetine capsules are not indicated for the treatment of any psychiatric condition. Paroxetine capsules contain a lower dose of paroxetine than that used to treat depression, obsessive compulsive disorder, panic disorder, generalized anxiety disorder, social anxiety disorder, and post-traumatic stress disorder. The safety and efficacy of this lower dose of paroxetine in paroxetine capsules have not been established for any ps…

Drug Interaction: Minor

The interaction between atenolol and paroxetine is generally considered minor. While paroxetine is a potent CYP2D6 inhibitor, atenolol is primarily renally cleared and not significantly metabolized by CYP2D6, minimizing pharmacokinetic interaction risk. However, both drugs can independently cause bradycardia, so additive pharmacodynamic effects are theoretically possible, though less common with atenolol.

Mechanism: Paroxetine is a potent inhibitor of CYP2D6. However, atenolol is predominantly eliminated by renal excretion of unchanged drug, with minimal hepatic metabolism by CYP2D6. Therefore, paroxetine's CYP2D6 inhibition is unlikely to significantly alter atenolol plasma levels. Both drugs can independently cause bradycardia, suggesting a potential, albeit low, pharmacodynamic additive effect.
