Overview
Carteolol Hydrochloride Ophthalmic Solution USP, 1% is a nonselective beta-adrenoceptor blocking agent for ophthalmic use. The chemical name for carteolol hydrochloride is (±)-5-[3-[(1,1-dimethylethyl) amino]-2-hydroxypropoxy]-3,4-dihydro-2(1H)-quinolinone monohydrochloride. The structural formula is as follows: C 16 H 24 N 2 O 3 •HCI Mol. Wt. 328.84 Each mL of sterile solution contains Active: carteolol hydrochloride 10 mg (1%). Preservative: benzalkonium chloride 0.05 mg (0.005%). Inactives: sodium chloride, monobasic and dibasic sodium phosphate, sodium hydroxide and/or hydrochloric acid (to adjust pH to 6.0 - 8.0) and purified water. chemical
Indications & Usage
Carteolol Hydrochloride Ophthalmic Solution 1% has been shown to be effective 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.
Dosage & Administration
The usual dose is one drop of Carteolol Hydrochloride Ophthalmic Solution 1% in the affected eye(s) twice a day. If the patient's IOP is not at a satisfactory level on this regimen, concomitant therapy with pilocarpine and other miotics, and/or epinephrine or dipivefrin, and/or systemically administered carbonic anhydrase inhibitors, such as acetazolamide, can be instituted.
Warnings & Precautions
WARNINGS 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. For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and rarely death in association with cardiac failure, have been reported with topical application of beta-adrenergic blocking agents (see CONTRAINDICATIONS ). Cardiac Failure: Sympathetic stimulation may be essential for support of the circulation in individuals with diminished myocardial contractility, and its inhibition by beta-adrenergic receptor blockade may precipitate more severe failure. In Patients Without a History of Cardiac Failure: Continued depression of the myocardium with beta-blocking agents over a period of time can, in some cases, lead to cardiac failure. At the first sign or symptom of cardiac failure, Carteolol Hydrochloride should be discontinued. Non-Allergic Bronchospasm: In patients with non-allergic bronchospasm or with a history of non-allergic bronchospasm (e.g., chronic bronchitis, emphysema), Carteolol Hydrochloride Ophthalmic Solution should be administered with caution since it may block bronchodilation produced by endogenous and exogenous catecholamine stimulation of beta 2 receptors. Major Surgery: The necessity or desirability of withdrawal of beta-adrenergic blocking agents prior to major surgery is controversial. Beta-adrenergic receptor blockade impairs the ability of the heart to respond to beta-adrenergically mediated reflex stimuli. This may augment the risk of general anesthesia in surgical procedures. Some patients receiving beta-adrenergic receptor blocking agents have been subject to protracted severe hypotension during anesthesia. For these reasons, in patients undergoing elective surgery, gradual withdrawal of beta-adrenergic receptor blocking agents may be appropriate. If necessary during surgery, the effects of beta-adrenergic blocking agents may be reversed by sufficient doses of such agonists as isoproterenol, dopamine, dobutamine or levarterenol (see OVERDOSAGE ). Diabetes Mellitus: 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. Beta-adrenergic receptor blocking agents may mask the signs and symptoms of acute hypoglycemia. Thyrotoxicosis: Beta-adrenergic blocking agents may mask certain clinical signs (e.g., tachycardia) of hyperthyroidism. Patients suspected of developing thyrotoxicosis should be managed carefully to avoid abrupt withdrawal of beta-adrenergic blocking agents which might precipitate a thyroid storm.
Contraindications
Carteolol is contraindicated in those individuals with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease (see WARNINGS ); sinus bradycardia; second- and third-degree atrioventricular block; overt cardiac failure (see WARNINGS ); cardiogenic shock; or hypersensivity to any component of this product.
Adverse Reactions
The following adverse reactions have been reported in clinical trials with Carteolol Hydrochloride Ophthalmic Solution. Ocular: Transient eye irritation, burning, tearing, conjunctival hyperemia and edema occurred in about 1 of 4 patients. Ocular symptoms including blurred and cloudy vision, photophobia, decreased night vision, and ptosis and ocular signs including blepharoconjunctivitis, abnormal corneal staining, and corneal sensitivity occurred occasionally. Systemic: As is characteristic of nonselective adrenergic blocking agents, Carteolol may cause bradycardia and decreased blood pressure (See WARNINGS ). 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. The following additional adverse reactions have been reported with ophthalmic use of beta 1 and beta 2 (nonselective) adrenergic receptor blocking agents: Body As a Whole: Headache Cardiovascular: Arrhythmia, syncope, heart block, cerebral vascular accident, cerebral ischemia, congestive heart failure, palpitation (see WARNINGS ). Digestive: Nausea Psychiatric: Depression Skin: Hypersensitivity, including localized and generalized rash Respiratory: Bronchospasm (predominantly in patients with pre-existing bronchospastic disease), respiratory failure (see WARNINGS ) Endocrine: Masked symptoms of hypoglycemia in insulin-dependent diabetics (see WARNINGS ) Special Senses: Signs and symptoms of keratitis, blepharoptosis, visual disturbances including refractive changes (due to withdrawal of miotic therapy in some cases), diplopia, ptosis. Other reactions associated with the oral use of nonselective adrenergic receptor blocking agents should be considered potential effects with ophthalmic use of these agents.
Drug Interactions
Carteolol Hydrochloride Ophthalmic Solution should be used with caution in patients who are receiving a beta-adrenergic blocking agent orally, because of the potential for additive effects on systemic beta-blockade. Close observation of the patient is recommended when a beta-blocker is administered to patients receiving catecholamine-depleting drugs such as reserpine, because of possible additive effects and the production of hypotension and/or marked bradycardia, which may produce vertigo, syncope, or postural hypotension.
