  • Timolol and Brimonidine

Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Solution, ophthalmic [drops]:

Combigan: Brimonidine tartrate 0.2% and timolol 0.5% (5 mL,10 mL) [contains benzalkonium chloride]

Brand Names: U.S.

  • Combigan

Pharmacologic Category

  • Alpha2 Agonist, Ophthalmic
  • Beta-Blocker, Nonselective
  • Ophthalmic Agent, Antiglaucoma

Pharmacology

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

Timolol: Blocks both beta-1 and beta-2 adrenergic receptors, reduces intraocular pressure by reducing aqueous humor production or possibly outflow; reduces blood pressure by blocking adrenergic receptors and decreasing sympathetic outflow, produces a negative chronotropic and inotropic activity by blocking beta-1 adrenergic receptors

Use: Labeled Indications

Elevated intraocular pressure: For the reduction of elevated intraocular pressure (IOP) in patients with glaucoma or ocular hypertension who require adjunctive or replacement therapy because of inadequately controlled IOP.

Contraindications

Reactive airway disease, including bronchial asthma; history of bronchial asthma; severe chronic obstructive pulmonary disease (COPD); sinus bradycardia, second- or third-degree atrioventricular block, overt cardiac failure, cardiogenic shock; known hypersensitivity to brimonidine/timolol or any component of the formulation; neonates, infants, and children younger than 2 years.

Canadian labeling: Additional contraindications (not in US labeling): Monoamine oxidase (MAO) inhibitor therapy (concurrent or within 14 days); sick sinus syndrome; sinoatrial nodal block

Dosing: Adult

Dosing: Pediatric

Elevated intraocular pressure: Children ≥2 years: Ophthalmic: Instill 1 drop into affected eye(s) twice daily

Note: In the Canadian labeling, use in children (at any age) is not recommended

Drug Interactions

Abiraterone Acetate: May increase the serum concentration of CYP2D6 Substrates.

Warnings/Precautions

Concerns related to adverse effects:

• Anaphylactic reactions: Use caution with history of severe anaphylaxis to a variety of allergens; patients taking beta-blockers may become more sensitive to repeated challenges. Treatment of anaphylaxis (eg, epinephrine) in patients taking beta-blockers may be ineffective or promote undesirable effects.

• Bacterial keratitis: Inadvertent contamination of multiple-dose ophthalmic solutions has the potential to cause bacterial keratitis.

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

• Hypersensitivity: Ocular hypersensitivity reactions have been reported with brimonidine; reactions may cause an increase in intraocular pressure.

• Ocular effects: Use of agents that reduce/suppress aqueous humor production has been associated with choroidal detachment after filtration procedures.

Disease-related concerns:

• Angle-closure glaucoma: Appropriate use: Not for use alone to treat acute angle-closure glaucoma (has no effect on papillary constriction).

• Cardiovascular disease: Use with caution in patients with compensated heart failure or coronary insufficiency. Contraindicated in patients with overt heart failure. Monitor for signs/symptoms of heart failure and discontinue use immediately if suspected. May impair compensatory tachycardia and increase hypotension risk. Use with caution in patients with orthostatic hypotension.

• Cerebrovascular disease: Use with caution in cerebrovascular insufficiency; consider alternative therapy for patients with signs/symptoms of decreased cerebral blood flow after therapy initiation.

• Depression: Use with caution in patients with depression.

• Diabetes: Use with caution in patients with diabetes mellitus; may potentiate hypoglycemia and/or mask signs and symptoms.

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

• Myasthenia gravis: Use with caution in patients with myasthenia gravis; may worsen disease or other myasthenic symptoms (diplopia, ptosis, and generalized weakness).

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

• Respiratory disease: In general, patients with mild to moderate chronic obstructive pulmonary disease (COPD) or bronchospastic disease should not receive beta-blockers; if used at all, should be used cautiously with close monitoring. Use is contraindicated in patients with asthma or severe COPD.

• Thyroid disease: May mask signs of hyperthyroidism (eg, tachycardia). If thyrotoxicosis is suspected, carefully manage and monitor; abrupt withdrawal may exacerbate symptoms of hyperthyroidism or precipitate thyroid storm.

• Vascular insufficiency: Can precipitate or aggravate symptoms of arterial insufficiency in patients with PVD, Raynaud disease, and thromboangiitis obliterans. Use with caution and monitor for progression of arterial obstruction.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Contact lens wearers: Product contains benzalkonium chloride which may be absorbed by soft contact lenses; remove lens prior to administration and wait 15 minutes before reinserting.

• Pediatric: Safety and efficacy have not been established in children <2 years of age; use is contraindicated in children <2 years of age. Note: In the Canadian labeling, use in children (at any age) is not recommended.

Other warnings/precautions:

• Surgery: May block systemic effects of beta agonists (eg, epinephrine, norepinephrine); notify anesthesiologist if patient is receiving ophthalmic beta-blocker therapy. Patients undergoing planned major surgery should be gradually tapered off therapy (if possible) prior to procedure. If necessary during surgery, effects of beta-blocker therapy may be reversed by adrenergic agonists.

Monitoring Parameters

Intraocular pressure; monitor for systemic effect of beta-blockade with ophthalmic administration; blood pressure

Pregnancy Considerations

There are no adequate and well-controlled studies in pregnant women with the combination product. Also see individual agents.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience itching, burning, stinging, or fatigue. Have patient report immediately to prescriber vision changes, eye pain, severe eye irritation, shortness of breath, excessive weight gain, swelling of arms or legs, bradycardia, abnormal heartbeat, angina, dizziness, passing out, difficulty breathing, or muscle weakness (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.

Intended Use and Disclaimer: Should not be printed and given to patients. This information is intended to serve as a concise initial reference for health care professionals to use when discussing medications with a patient. You must ultimately rely on your own discretion, experience, and judgment in diagnosing, treating, and advising patients.
