🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionDorzolamide and timolol are absorbed systemically after topical ocular administration. Systemic absorption of dorzolamide is low but measurable. Timolol can be absorbed systemically and may cause effects similar to oral beta-blockers.
DistributionNot established from the available information.
Protein BindingDorzolamide is approximately 33% bound to plasma proteins. Timolol is approximately 10% bound to plasma proteins.
MetabolismDorzolamide is metabolized by cytochrome P450 enzymes to a less active metabolite. Timolol is extensively metabolized in the liver, primarily by CYP2D6.
Half-LifeThe elimination half-life of dorzolamide is approximately 4 months for the metabolite, but the parent drug has a shorter half-life. Timolol has a plasma half-life of about 3 to 4 hours.
ExcretionDorzolamide and its metabolites are excreted primarily in the urine. Timolol and its metabolites are excreted in the urine.
BioavailabilitySystemic bioavailability of dorzolamide after ocular administration is low, approximately 10-15%. Timolol systemic bioavailability after ocular administration is about 60-70%.
Onset of ActionThe onset of intraocular pressure reduction is within 1 hour after instillation.
Peak Plasma TimePeak plasma concentrations of dorzolamide occur about 1-2 hours after ocular administration. Timolol peak plasma levels occur within 1-2 hours.
Duration of ActionThe intraocular pressure-lowering effect lasts for approximately 12 to 24 hours, allowing twice-daily dosing.

How It Works

This medicine combines two active ingredients that lower intraocular pressure by reducing the production of aqueous humor. Dorzolamide is a carbonic anhydrase inhibitor that blocks the enzyme carbonic anhydrase in the ciliary body, leading to decreased bicarbonate and fluid secretion. Timolol is a non-selective beta-adrenergic receptor blocker that reduces cyclic AMP production in the ciliary epithelium, thereby decreasing aqueous humor formation. The combined effect is a greater reduction in eye pressure than either agent alone.

Mechanism Steps

1
Dorzolamide inhibits carbonic anhydrase: Dorzolamide binds to and inhibits carbonic anhydrase in the ciliary body, reducing the formation of bicarbonate and fluid.
2
Timolol blocks beta-adrenergic receptors: Timolol blocks beta-1 and beta-2 receptors on the ciliary epithelium, decreasing cyclic AMP and aqueous humor production.
3
Reduced aqueous humor secretion: The combined action lowers the rate at which fluid enters the eye, thereby reducing intraocular pressure.
4
Lowered intraocular pressure: The decrease in eye pressure helps prevent damage to the optic nerve and slows the progression of glaucoma.
