Warnings/Precautions

Concerns related to adverse effects:

• Bacterial keratitis: Inadvertent contamination of multiple-dose ophthalmic solutions has caused bacterial keratitis.

• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with severe cardiovascular disease or coronary insufficiency.

• Cerebrovascular insufficiency: Use with caution in patients with cerebral insufficiency.

• Hepatic impairment: Use with caution in patients with hepatic impairment (has not been studied).

• Orthostatic hypotension: Use with caution in patients with orthostatic hypotension.

• Raynaud phenomenon: Use with caution in patients with Raynaud phenomenon.

• Renal impairment: Use with caution in patients with renal impairment (has not been studied).

• Thromboangiitis obliterans: Use with caution in patients with thromboangiitis obliterans.

Special populations:

• Contact lens wearers: Some formulations may contain benzalkonium chloride which may be adsorbed by soft contact lenses; remove contacts prior to administration and wait 15 minutes before reinserting.

• Pediatric: Systemic absorption has been reported; children are at higher risk of systemic adverse events (Levy 2004).

Other warnings/precautions:

• Self-medication (OTC use): Discontinue use and contact health care provider if eye pain or changes in vision occur; redness or irritation of the eye continues, or condition worsens or persists for >3 days. Do not use if solution changes color or becomes cloudy.

Warnings: Additional Pediatric Considerations

May cause CNS depression, particularly in young children; not recommended for use in infants or children <2 years. The most common adverse effects reported in a study of pediatric glaucoma patients were somnolence and decreased alertness (50% to 83% in children 2 to 6 years of age); these effects resulted in a 16% discontinuation of treatment rate; children >7 years (>20 kg) had a much lower rate of somnolence (25%); apnea, bradycardia, hypotension, hypothermia, hypotonia, and somnolence have been reported in infants receiving brimonidine.

Monitoring Parameters

IOP routinely (first month of therapy may not reflect long-term level of IOP reduction)

Mechanism of Action

A relatively selective alpha-2 adrenergic agonist; causes reduction of aqueous humor formation and increased uveoscleral outflow

Pharmacokinetics (Adult Data Unless Noted)

Protein binding: ~29%.

Metabolism: Hepatic (extensive).

Half-life elimination: ~3 hours.

Time to peak, plasma: 1 to 4 hours.

Excretion: Urine (74%).
