What is Timoptol used for?
Timoptol contains a substance called timolol which belongs to a group of medicines called beta-blockers. Timolol lowers the pressure in your eye(s). It is used to treat glaucoma, when the pressure in the eye is raised.
What is the difference between Timoptol and Timoptol XE?
TIMOPTOL-XE (Timolol maleate) is a formulation of TIMOPTOL (Timolol maleate) containing a novel delivery vehicle. It is available with preservative, benzododecinium bromide. TIMOPTOL-XE reduces elevated and normal intraocular pressure whether or not associated with glaucoma.
What is the difference between timolol and timoptic?
Timoptic is a brand-name drug that contains the active drug timolol. This active drug is also available as a generic medication. A generic drug is an exact copy of the active drug in a brand-name medication.
What is the mechanism of action of timolol?
The mechanism of action of timolol is probably the reduction of the formation of aqueous humor in the ciliary body in the eye. It was the first beta blocker approved for topical use in treatment of glaucoma in the United States (1978).
What receptors does timolol use?
Since timolol blocks vasodilator beta-2 receptors in the resistance vessels, the increased sympathetic tone acts unopposed on alpha-1 receptors, which cause vasoconstriction.
Does timolol cause pupil dilation?
Topical administration of timolol maleate resulted in reduction of IOP and pupil diameter in treated and contralateral eyes, thus supporting the use of timolol for treatment of glaucoma in dogs. Miosis indicates possible beta-adrenergic inhibition or alpha-adrenergic activation of the sphincter muscle.
Is Timoptol a beta-blocker?
Timolol eye drops is used alone or together with other medicines to treat increased pressure in the eye that is caused by open-angle glaucoma or a condition called ocular (eye) hypertension. This medicine is a beta-blocker.
What is timolol ex?
This medication belongs to the family of medications called beta-blockers. Timolol eye drops are used to treat glaucoma and increased pressure in the eye. This medication works by reducing the production of fluid in the eye, thereby lowering the pressure in the eye.
What is another name for timolol?
Timolol is a prescription drug in a group of drugs called beta-blockers. Beta-blockers affect the heart and circulation (blood flow through arteries and veins). Timolol is available under the following different brand names: Blocadren and Timol.
Is timolol a ACE inhibitor?
Dorzolamide HCl/ timolol maleate (Cosopt, Cosopt PF) Carbonic anhydrase inhibitor that may decrease aqueous humor secretion, causing a decrease in IOP.
Does timolol cause vasoconstriction?
Results showed that 0.5% timolol may have a vasoconstrictive effect on the retinal arteries of normal human subjects after 1 week of unilateral instillation twice daily. We suggest that this arterial vasoconstriction could be caused by the effect of timolol on the vascular beta-2 receptors.
Does timolol affect pupil size?
Topical administration of timolol maleate resulted in reduction of IOP and pupil diameter in treated and contralateral eyes, thus supporting the use of timolol for treatment of glaucoma in dogs.
Does timolol change eye color?
Eye color may change to a brown color. This change may be long-lasting. Eye color changes may happen a few months to years after starting latanoprost and timolol. If eye color changes, call the doctor.
What can I monitor with timolol?
Ocular pressure, systemic effects of beta-blockade, blood pressure, heart rate, apical pulses, and radial pulses all require monitoring while a patient is on timolol.
Is timolol lipophilic?
Purpose: The purpose of this work was to study the effect of electroporation on iontophoretic transport of two beta-blockers, timolol (lipophilic) and atenolol (hydrophilic), and to have a better understanding of the mechanism of combination.
Is timolol a diuretic?
TIMOLIDE* (Timolol Maleate-Hydrochlorothiazide) is for the treatment of hyper-tension. It combines the antihyper-tensive activity of two agents: a non-selective beta-adrenergic receptor blocking agent (timolol maleate) and a diuretic (hydrochlorothiazide).
Does timolol cause vasodilation?
Does timolol cause miosis?
Summary. Timolol maleate is a new, potent ocular antihypertensive that has an effect additive with other antiglaucoma medications. It does not cause miosis and is relatively free of ocular complications, although a few have been documented.
