in the eye of people with glaucoma or
high pressure in the eye.

that
reduces
the
amount
of
fluid
produced in the eye and increases the
amount of fluid flowing out of the eye.
This reduces the pressure inside the eye.

ALPHAGAN ®
Brimonidine tartrate
ophthalmic solution 0.2%
DESCRIPTION
Each mL contains: brimonidine tartrate 2 mg (equivalent to 1.32 mg as brimonidine free base) with:
benzalkonium chloride 0.05 mg, polyvinyl alcohol 14 mg; sodium chloride; sodium citrate; citric acid and
purified water.
CLINICAL PHARMACOLOGY
ALPHAGAN ® is a relatively selective alpha- 2 adrenergic agonist. It has a peak ocular hypotensive effect
occurring at two hours post -dosing. Fluorophotometric studies in animals and humans suggest that
brimonidine tartrate has a dual mechanism of action by reducing aqueous humor production and
increasing uveoscleral outflow.
After ocular administration of a 0.2% solution, plasma concentrations peaked within 1 to 4 hours and
declined with a system ic half -life of approximately 3 hours.
In humans, system ic metabolism of brimonidine is extensive. It is metabolized primarily by the liver.
Urinary excretion is the major route of elimination of the drug and its metabolites. Approximately 87% of
an orally -administered radioactive dose was eliminated within 120 hours, with 74% found in the urine.
Elevated IOP presents a major risk factor in glaucomatous field loss. The higher the level of IOP, the
greater the likelihood of optic nerve damage and visual field loss. ALPHAGAN
® has the action of lowering
intraocular pressure with minimal effect on cardiovascular and pulmonary parameters.
In comparative clinical studies with timolol 0.5%, lasting up to one year, the IOP lowering effect of
ALPHAGAN ® was approximately 4 -6 mm Hg compared with approximately 6 mm Hg for timolol. Eight
percent of subjects were discontinued from studies due to inadequately controlled intraocular pressure,
which in 30% of these patients occurred during the first month of therapy. Approximately 20% were
discontinued due to adverse experiences.
INDICATIONS AND USAGE
ALPHAGAN ® is indicated for lowering intraocular pressure in patients with open- angle glaucoma or ocular
hypertension. The IOP lowering efficacy of ALPHAGAN ® ophthalmic
