Brimonidine tartrate is a relatively selective alpha-2 adrenergic receptor agonist that, in radioligand binding assays and in functional assays, is approximately 1000 times more selective for the alpha-2 adrenoceptor than the alpha-1 adrenoceptor. This selectivity results in the absence of vasoconstriction in microvessels associated with human retinal xenografts.Topical administration of brimonidine decreases IOP in humans. When used as directed, Alphagan P 0.15% ophthalmic solutions reduce elevated IOP with minimal effect on cardiovascular parameters.Brimonidine tartrate has a rapid onset of action, with the peak ocular hypotensive effect occurring at approximately two hours post-dosing. The duration of effect is 12 hours or greater.Fluorophotometric studies in animals and humans suggest that Alphagan P 0.15% has a dual mechanism of action. Alphagan P 0.15% ophthalmic solution 0.15% lowers IOP by reducing aqueous humor production and increasing uveoscleral outflow.

0.2% ophthalmic solution: The recommended dose is one drop of 0.2% ophthalmic solution in the affected eye(s) three times daily, approximately 8 hours apart. This ophthalmic solution may be used concomitantly with other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic product is being used, the products should be administered at least 5 minutes apart.0.15% ophthalmic solution: The recommended dose is one drop of 0.15% ophthalmic solution in the affected eye(s) three times daily, approximately 8 hours apart.0.025% ophthalmic solution: Instill 1 drop in the affected eye(s) every 6-8 hours. Do not use it more than 4 times daily. If more than one topical ophthalmic product is being used, the products should be administered at least 5 minutes apart.

Do not allow the dropper tip of the bottle to touch the eye or other surrounding structures, because this could cause eye injury or contaminate the tip with common bacteria known to cause eye infections. Serious damage to the eye with subsequent loss of vision may result if you use eye drop solutions that have become contaminated. If you experience any type of eye condition or have surgery, immediately seek your doctor’s advice concerning the continued use of the bottle you are using.

Although specific drug interaction studies have not been conducted with Alphagan P 0.15% ophthalmic solution, the possibility of an additive or potentiating effect with CNS depressants (alcohol, barbiturates, opiates, sedatives, or anesthetics) should be considered. Alpha-agonists, as a class, may reduce pulse and blood pressure. Caution in using concomitant drugs such as beta-blockers (ophthalmic and systemic), antihypertensives and/or cardiac glycosides is advised. Tricyclic antidepressants have been reported to blunt the hypotensive effect of systemic clonidine. It is not known whether the concurrent use of these agents with Alphagan P 0.15% ophthalmic solution in humans can lead to resulting interference with the IOP lowering effect. No data on the level of circulating catecholamines after administration of Alphagan P 0.15% ophthalmic solution are available. Caution, however, is advised in patients taking Tricyclic antidepressants which can affect the metabolism and uptake of circulating amines.

Alphagan P 0.15% ophthalmic solution is contraindicated in patients with hypersensitivity to Alphagan P 0.15%. It is also contraindicated in patients receiving monoamine oxidase (MAO) inhibitor therapy.

Adverse events occurring in approximately 10-30% of the subjects, in descending order of incidence, included oral dryness, ocular hyperemia, burning and stinging, headache, blurring, foreign body sensation, fatigue/drowsiness, conjunctival follicles, ocular allergic reactions, and ocular pruritus. Events occurring in approximately 3-9% of the subjects, in descending order included corneal staining/erosion, photophobia, eyelid erythema, ocular ache/pain, ocular dryness, tearing, upper respiratory symptoms, eyelid edema, conjunctival edema, dizziness, blepharitis, ocular irritation, gastrointestinal symptoms, asthenia, conjunctival blanching, abnormal vision and muscular pain. The following adverse reactions were reported in less than 3% of the patients: lid crusting, conjunctival hemorrhage, abnormal taste, insomnia, conjunctival discharge, depression, hypertension, anxiety, palpitations/arrhythmias, nasal dryness and syncope.

There are no studies of Alphagan P 0.15% in pregnant women. Studies in rats have indicated brimonidine is excreted in the milk of the lactating rat. Since it is not known whether this drug is excreted in human milk, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Although Alphagan P 0.15% ophthalmic solution had minimal effect on the blood pressure of patients in clinical studies, caution should be exercised in treating patients with severe cardiovascular disease. Alphagan P 0.15% ophthalmic solution should be used with caution in patients with depression, cerebral or coronary insufficiency, Raynaud's phenomenon, orthostatic hypotension or thromboangiitis obliterans.

Store below 30°C in a cool and dry place protected from light. Keep out of reach of children. Do not touch the dropper tip to surfaces since this may contaminate the solution. Do not use after 30 days of first opening.

Geriatrics (> 65 years of age): No overall difference in safety and effectiveness has been observed between elderly and other adult patients.Children under the age of 2 years: The use of Alphagan P 0.15% ophthalmic solution 0.15% in neonates and infants is contraindicated.Children (2-18 years of age): The use of Alphagan P 0.15% ophthalmic solution 0.15% is currently not recommended in children

Brimonidine is an α-2 adrenoreceptor agonist that is more selective for the α-2 adrenoreceptor than α-1. Topical administration of Alphagan P 0.15% eye drops decreases intraocular pressure (IOP) in humans. When used as directed Alphagan P 0.15% have the action of reducing elevated IOP with minimal effect on cardiovascular parametres. Alphagan P 0.15% eye drops have a rapid onset of action with the peak ocular hypotensive effect occurring at two hours post-dosing. The duration of effect is 12 hours or greater. Fluorophotometric studies in animals and humans suggest that Alphagan P 0.15% has a dual mechanism of action. Alphagan P 0.15% eye drops lower IOP by reducing aqueous humor production and enhancing uveoscleral outflow.

There are no adequate and well-controlled studies in pregnant women. In animal studies, Brimonidine crossed the placenta and entered into the fetal circulation to a limited extent. Alphagan P 0.15% ophthalmic solution 0.2% should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus. It is not known whether this drug is excreted in human milk; in animal studies Alphagan P 0.15% was excreted in breast milk. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
