What are the uses of this medicine?

• Carteolol is used in lowering intraocular pressure and may be used in patients with chronic open-angle glaucoma and intraocular hypertension.
• It may be used alone or in combination with other intraocular pressure lowering medications.

How does this medicine work?

• Carteolol is a nonselective beta-adrenergic blocking agent with associated intrinsic sympathomimetic activity and without significant membrane-stabilizing activity.
• Carteolol Hydrochloride reduces normal and elevated intraocular pressure (IOP) whether or not accompanied by glaucoma.
• The exact mechanism of the ocular hypotensive effect of beta-blockers has not been definitely demonstrated.

What side effects can this medication cause?

The most common side effects of this medicine include:

• Transient eye irritation, burning, tearing, conjunctival hyperemia, edema, blurred and cloudy vision, photophobia, decreased night vision, and ptosis and ocular signs including blepharoconjunctivitis, abnormal corneal staining, and corneal sensitivity

The following systemic events have occasionally been reported with the use of Carteolol Hydrochloride Ophthalmic Solution:

• cardiac arrhythmia, heart palpitation, dyspnea, asthenia, headache, dizziness, insomnia, sinusitis, and taste perversion.

Less common side effects, may include:

• Body As a Whole: Headache
• Cardiovascular: Arrhythmia, syncope, heart block, cerebral vascular accident, cerebral ischemia, congestive heart failure, palpitation.
• Digestive: Nausea
• Psychiatric: Depression
• Skin: Hypersensitivity, including localized and generalized rash
• Respiratory: Bronchospasm (predominantly in patients with pre-existing bronchospastic disease), respiratory failure
• Endocrine: Masked symptoms of hypoglycemia in insulin-dependent diabetics
• Special Senses: Signs and symptoms of keratitis, blepharoptosis, visual disturbances including refractive changes (due to withdrawal of miotic therapy in some cases), diplopia, ptosis.

What special precautions should I follow?

• Carteolol has not been detected in plasma following ocular instillation. However, as with other topically applied ophthalmic preparations, Carteolol may be absorbed systemically. The same adverse reactions found with systemic administration of beta-adrenergic blocking agents may occur with topical administration.
• Carteolol Hydrochloride Ophthalmic Solution should be used with caution in patients with known hypersensitivity to other beta-adrenoceptor blocking agents.
• Use with caution in patients with known diminished pulmonary function.
• In patients with angle-closure glaucoma, the immediate objective of treatment is to reopen the angle. This requires constricting the pupil with a miotic. Carteolol has little or no effect on the pupil. When Carteolol is used to reduce elevated intraocular pressure in angle-closure glaucoma, it should be used with a miotic and not alone.
• Beta-adrenergic blockade has been reported to potentiate muscle weakness consistent with certain myasthenic symptoms (e.g., diplopia, ptosis and generalized weakness).
• Beta-adrenergic blocking agents should be administered with caution in patients subject to spontaneous hypoglycemia or to diabetic patients (especially those with labile diabetes) who are receiving insulin or oral hypoglycemic agents.
• The necessity or desirability of withdrawal of beta-adrenergic blocking agents prior to major surgery is controversial. For these reasons, in patients undergoing elective surgery, gradual withdrawal of beta-adrenergic receptor blocking agents may be appropriate.
• Carteolol Hydrochloride Ophthalmic Solution should be administered with caution since it may block bronchodilation produced by endogenous and exogenous catecholamine stimulation of beta2 receptors.
• Caution should be exercised when Carteolol Hydrochloride Ophthalmic Solution is administered to nursing mothers.

What to do in case of emergency/overdose?

Symptoms of overdosage may include:

• bradycardia, bronchospasm, congestive heart failure and hypotension

Management of overdosage:

• In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.

• In case of ingestion, treatment with Carteolol Hydrochloride Ophthalmic Solution should be discontinued and [[gastric lavage considered.
• The patient should be closely observed and vital signs carefully monitored.

The following additional measures should be considered as appropriate:

• Symptomatic Sinus Bradycardia or Heart Block: Administer atropine. If there is no response to vagal blockade, administer isoproterenol cautiously.
• Bronchospasm: Administer a beta2-stimulating agent such as isoproterenol and/or a theophylline derivative.
• Congestive Heart Failure: Administer diuretics and digitalis glycosides as necessary.
• Hypotension: Administer vasopressors such as intravenous dopamine, epinephrine or norepinephrine bitartrate.
