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.

Nadolol (Nadolol) is a type of medicine called a beta-blocker. It is prescribed to help manage chest pain (angina pectoris) and to lower high blood pressure (hypertension). By blocking certain natural chemicals in the body, Nadolol helps to slow the heart rate and relax blood vessels, making it easier for the heart to pump blood.

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)
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 .
Nadolol
INDICATIONS AND USAGE Angina Pectoris Nadolol tablets, USP is indicated for the long-term management of patients with angina pectoris. Hypertension Nadolol tablets, USP is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal 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 the class to which this drug principally belongs. There are no controlled trials demonstrating…

Drug Interaction: Minor
A clinically significant pharmacokinetic interaction between nadolol and citalopram is unlikely due to nadolol's primary renal clearance and citalopram's minimal inhibition of relevant CYP enzymes. However, both drugs can independently affect heart rate, and an additive pharmacodynamic effect resulting in bradycardia is theoretically possible, though rarely clinically significant.
Mechanism: Nadolol is primarily eliminated renally, with minimal involvement of CYP450 enzymes. Citalopram is a weak inhibitor of CYP2D6 and other CYP enzymes, which are not primary metabolic pathways for nadolol. Therefore, a pharmacokinetic interaction is not expected. A minor pharmacodynamic interaction is possible due to the additive potential for bradycardia.
