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.

Timolol Maleate is an eye drop medication used to treat high pressure inside the eye. It works by helping to reduce the amount of fluid your eye produces, which in turn lowers the pressure. This medication is primarily prescribed for conditions like ocular hypertension and open-angle glaucoma to help protect your vision.

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).
Timolol Maleate
Mechanism of Action Timolol maleate is a beta 1 and beta 2 (non-selective) adrenergic receptor blocking agent that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anesthetic (membrane-stabilizing) activity. Timolol Maleate Ophthalmic Gel Forming Solution, when applied topically on the eye, has the action of reducing elevated, as well as normal intraocular pressure, whether or not accompanied by glaucoma. Elevated intraocular pressure is a major risk fa…

Patients can often find significant savings by using discount cards or manufacturer coupons, especially if a specific brand formulation is prescribed.
Drug Interaction: Moderate
Citalopram can inhibit the metabolism of timolol, potentially increasing timolol plasma concentrations and enhancing its beta-blocking effects. This can lead to an increased risk of bradycardia, hypotension, and other systemic beta-blocker adverse effects, especially given timolol's systemic absorption even from ophthalmic administration.
Mechanism: Citalopram is a moderate inhibitor of CYP2D6, which is involved in the metabolism of timolol. Inhibition of timolol's metabolism by citalopram can lead to elevated plasma levels of timolol. Additionally, both drugs can independently cause bradycardia, leading to an additive pharmacodynamic effect.
