Cartrol: Full Drug Profile

Medically reviewed by Min Clinic Staff | Updated: January 2026

Cartrol - General Information

A beta-adrenergic antagonist used as an anti-arrhythmia agent, an anti-angina agent, an antihypertensive agent, and an antiglaucoma agent.

 

Pharmacology of Cartrol

Cartrol is a beta1 and beta2 (non-selective) adrenergic receptor-blocking agent that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anesthetic (membrane-stabilizing) activity. Cartrol, when applied topically to 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 factor in the pathogenesis of glaucomatous visual field loss and optic nerve damage. Cartrol reduces intraocular pressure with little or no effect on pupil size or accommodation in contrast to the miosis which cholinergic agents are known to produce.

 

Cartrol for patients

 

Cartrol Interactions

Ocupress should be used with caution in patients who are receiving a beta-adrenergic blocking agent orally because of the potential for additive effects on systemic beta-blockade.

Close observation of the patient is recommended when a beta-blocker is administered to patients receiving catecholamine-depleting drugs such as reserpine, because of possible additive effects and the production of hypotension and/or marked bradycardia, which may produce vertigo, syncope, or postural hypotension.

 

Cartrol Contraindications

Ocupress Ophthalmic Solution is contraindicated in those individuals with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease; sinus bradycardia; second- and t.i.d. degree atrioventricular block; overt cardiac failure ; cardiogenic shock; or hypersensitivity to any component of this product.
