Overview

Brimonidine (ophthalmic) is an alpha-2 adrenergic agonist that is FDA approved for the treatment of open-angle glaucoma or ocular hypertension. Common adverse reactions include hypertension, contact dermatitis, erythema, flushing, sensation of burning of skin, xerostomia, somnolence, allergic conjunctivitis, burning sensation in eye, conjunctival discoloration, conjunctival hyperemia, follicular conjunctivitis, acute hypersensitivity reaction, itching of eye, lid retraction, and visual disturbance.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Ocular Hypertension

  • Dosing information
  • Recommended dose is one drop three times daily, approximately 8 hours apart. Brimonidine ophthalmic solution may be used concomitantly with other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic product is to be used, the different products should be instilled at least 5 minutes apart.

Contraindications

Neonates and Infants (under the age of 2 years)

  • Brimonidine is contraindicated in neonates and infants (under the age of 2 years).

Hypersensitivity Reactions

  • Brimonidine is contraindicated in patients who have exhibited a hypersensitivity reaction to any component of this medication in the past.

Warnings

Potentiation of Vascular Insufficiency

Severe Cardiovascular Disease

  • Although brimonidine tartrate 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.

Contamination of Topical Ophthalmic Products After Use

  • There have been reports of bacterial keratitis associated with the use of multiple-dose containers of topical ophthalmic products. These containers had been inadvertently contaminated by patients who, in most cases, had a concurrent corneal disease or a disruption of the ocular epithelial surface.

Adverse Reactions

Clinical Trials Experience

Postmarketing Experience

Drug Interactions

Antihypertensives/Cardiac Glycosides

CNS Depressants

  • Although specific drug interaction studies have not been conducted with Brimonidine, the possibility of an additive or potentiating effect with CNS depressants (alcohol, barbiturates, opiates, sedatives, or anesthetics) should be considered.

Tricyclic Antidepressants

  • 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 Brimonidine in humans can lead to resulting interference with the IOP lowering effect. Caution is advised in patients taking tricyclic antidepressants which can affect the metabolism and uptake of circulating amines.

Monoamine Oxidase Inhibitors

  • Monoamine oxidase (MAO) inhibitors may theoretically interfere with the metabolism of brimonidine and potentially result in an increased systemic side-effect such as hypotension. Caution is advised in patients taking MAO inhibitors which can affect the metabolism and uptake of circulating amines.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): B

  • Teratogenicity studies have been performed in animals.
  • Brimonidine tartrate was not teratogenic when given orally during gestation days 6 through 15 in rats and days 6 through 18 in rabbits. The highest doses of brimonidine tartrate in rats (2.5 mg/kg/day) and rabbits (5.0 mg/kg/day) achieved AUC exposure values 360- and 20-fold higher, or 260- and 15-fold higher, respectively, than similar values estimated in humans treated with Brimonidine 0.1% or 0.15%, 1 drop in both eyes three times daily.
  • There are no adequate and well-controlled studies in pregnant women; however, in animal studies, brimonidine crossed the placenta and entered into the fetal circulation to a limited extent. Because animal reproduction studies are not always predictive of human response, Brimonidine should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus.


Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Brimonidine (ophthalmic) in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Brimonidine (ophthalmic) during labor and delivery.

Nursing Mothers

  • It is not known whether brimonidine tartrate is excreted in human milk, although in animal studies, brimonidine tartrate has been shown to be excreted in breast milk. Because of the potential for serious adverse reactions from Brimonidine in nursing infants, 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.

Pediatric Use

  • Brimonidine is contraindicated in children under the age of 2 years. During postmarketing surveillance, apnea, bradycardia, coma, hypotension, hypothermia, hypotonia, lethargy, pallor, respiratory depression, and somnolence have been reported in infants receiving brimonidine. The safety and effectiveness of brimonidine tartrate have not been studied in children below the age of 2 years.
  • In a well-controlled clinical study conducted in pediatric glaucoma patients (ages 2 to 7 years) the most commonly observed adverse reactions with brimonidine tartrate ophthalmic solution 0.2% dosed three times daily were somnolence (50-83% in patients ages 2 to 6 years) and decreased alertness. In pediatric patients 7 years of age (>20 kg), somnolence appears to occur less frequently (25%). Approximately 16% of patients on brimonidine tartrate ophthalmic solution discontinued from the study due to somnolence.

Geriatic Use

  • No overall differences in safety or effectiveness have been observed between elderly and other adult patients.

Gender

There is no FDA guidance on the use of Brimonidine (ophthalmic) with respect to specific gender populations.

Race

There is no FDA guidance on the use of Brimonidine (ophthalmic) with respect to specific racial populations.

Renal Impairment

Hepatic Impairment

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Brimonidine (ophthalmic) in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Brimonidine (ophthalmic) in patients who are immunocompromised.

Administration and Monitoring

Administration

Ophthalmic

Monitoring

FDA package insert for brimonidine contains no information regarding adverse reactions.

IV Compatibility

There is limited information about the IV compatibility.

Overdosage

  • Very limited information exists on accidental ingestion of brimonidine in adults; the only adverse reaction reported to date has been hypotension. Symptoms of brimonidine overdose have been reported in neonates, infants, and children receiving Brimonidine as part of medical treatment of congenital glaucoma or by accidental oral ingestion. Treatment of an oral overdose includes supportive and symptomatic therapy; a patent airway should be maintained.

Routes Ocular (eye drops), topical (gel)

Mechanism of Action

  • Brimonidine is a relatively selective alpha-2 adrenergic receptor agonist with 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.

Structure

  • Brimonidine (brimonidine tartrate ophthalmic solution) 0.1% or 0.15%, sterile, is a relatively selective alpha-2 adrenergic receptor agonist (topical intraocular pressure lowering agent).
  • The structural formula of brimonidine tartrate is:
This image is provided by the National Library of Medicine.
  • 5-Bromo-6-(2-imidazolidinylideneamino) quinoxaline L-tartrate; MW= 442.24
  • In solution, Brimonidine (brimonidine tartrate ophthalmic solution) has a clear, greenish-yellow color. It has an osmolality of 250-350 mOsmol/kg and a pH of 7.4-8.0 (0.1%) or 6.9-7.4 (0.15%).
  • Brimonidine tartrate appears as an off-white to pale-yellow powder and is soluble in both water (0.6 mg/mL) and in the product vehicle (1.4 mg/mL) at pH 7.7.
  • Each mL of Brimonidine contains the active ingredient brimonidine tartrate 0.1% (1 mg/mL) or 0.15% (1.5 mg/mL) with the inactive ingredients sodium carboxymethylcellulose; sodium borate; boric acid; sodium chloride; potassium chloride; calcium chloride; magnesium chloride; PURITE® 0.005% (0.05 mg/mL) as a preservative; purified water; and hydrochloric acid and/or sodium hydroxide to adjust pH.

Pharmacodynamics

There is limited information regarding Brimonidine (ophthalmic) Pharmacodynamics in the drug label.

Pharmacokinetics

Absorption

  • After ocular administration of either a 0.1% or 0.2% solution, plasma concentrations peaked within 0.5 to 2.5 hours and declined with a systemic half-life of approximately 2 hours.

Distribution

  • The protein binding of brimonidine has not been studied.

Metabolism

  • In humans, brimonidine is extensively metabolized by the liver.

Excretion

  • Urinary excretion is the major route of elimination of brimonidine and its metabolites. Approximately 87% of an orally-administered radioactive dose of brimonidine was eliminated within 120 hours, with 74% found in the urine.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

  • No compound-related carcinogenic effects were observed in either mice or rats following a 21-month and 24-month study, respectively. In these studies, dietary administration of brimonidine tartrate at doses up to 2.5 mg/kg/day in mice and 1 mg/kg/day in rats achieved 150 and 120 times or 90 and 80 times, respectively, the plasma Cmax drug concentration in humans treated with one drop of Brimonidine 0.1% or 0.15% into both eyes 3 times per day, the recommended daily human dose.
  • Brimonidine tartrate was not mutagenic or clastogenic in a series of in vitro and in vivo studies including the Ames bacterial reversion test, chromosomal aberration assay in Chinese Hamster Ovary (CHO) cells, and three in vivo studies in CD-1 mice: a host-mediated assay, cytogenetic study, and dominant lethal assay.
  • Reproduction and fertility studies in rats with brimonidine tartrate demonstrated no adverse effect on male or female fertility at doses which achieve up to approximately 125 and 90 times the systemic exposure following the maximum recommended human ophthalmic dose of Brimonidine 0.1% or 0.15%, respectively.

Clinical Studies

  • 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. Brimonidine tartrate has the action of lowering intraocular pressure with minimal effect on cardiovascular and pulmonary parameters.
  • Clinical studies were conducted to evaluate the safety, efficacy, and acceptability of Brimonidine (brimonidine tartrate ophthalmic solution) 0.15% compared with ALPHAGAN® administered three-times-daily in patients with open-angle glaucoma or ocular hypertension. Those results indicated that Brimonidine (brimonidine tartrate ophthalmic solution) 0.15% is comparable in IOP lowering effect to ALPHAGAN® (brimonidine tartrate ophthalmic solution) 0.2%, and effectively lowers IOP in patients with open-angle glaucoma or ocular hypertension by approximately 2-6 mmHg.
  • A clinical study was conducted to evaluate the safety, efficacy, and acceptability of Brimonidine (brimonidine tartrate ophthalmic solution) 0.1% compared with ALPHAGAN® administered three-times-daily in patients with open-angle glaucoma or ocular hypertension. Those results indicated that Brimonidine (brimonidine tartrate ophthalmic solution) 0.1% is equivalent in IOP lowering effect to ALPHAGAN® (brimonidine tartrate ophthalmic solution) 0.2%, and effectively lowers IOP in patients with open-angle glaucoma or ocular hypertension by approximately 2-6 mmHg.
