🔬 Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionMinimal systemic absorption after ocular administration; peak plasma concentration reached within 1-2 hours.

DistributionDistributes into ocular tissues; systemic distribution is limited due to low absorption.

Protein BindingApproximately 29% bound to plasma proteins.

MetabolismExtensively metabolized in the liver via aldehyde oxidase and cytochrome P450 enzymes.

Half-LifeApproximately 2-3 hours in plasma; ocular half-life is longer.

ExcretionPrimarily excreted in urine (74%) as metabolites; unchanged drug accounts for less than 5%.

BioavailabilityLow systemic bioavailability due to extensive first-pass metabolism and local administration.

Onset of ActionWithin 1-2 hours after instillation.

Peak Plasma Time1-2 hours after ocular administration.

Duration of ActionUp to 12 hours.

How It Works

Selective alpha-2 adrenergic receptor agonist that reduces aqueous humor production and increases uveoscleral outflow.

Mechanism Steps

1Brimonidine binds to alpha-2 adrenergic receptors on the ciliary epithelium and trabecular meshwork.

2Activation of Gi protein-coupled receptors inhibits adenylyl cyclase, reducing cAMP levels.

3Decreased cAMP leads to reduced aqueous humor production by the ciliary body.
