Iopidine Eye
Iopidine Eye - General Information
Iopidine Eye, also known as iopidine, is a sympathomimetic used in glaucoma therapy. It is an alpha2-adrenergic agonist.
Pharmacology of Iopidine Eye
Iopidine Eye significantly lowers intraocular pressure with minimal effects on cardiovascular and pulmonary parameters. It lowers intraocular pressure by reducing aqueous humor production and increasing uveoscleral outflow.
Iopidine Eye for patients
Iopidine Eye Interactions
Apraclonidine should not be used in patients receiving MAO inhibitors.. Although no specific drug interactions with topical glaucoma drugs or systemic medications were identified in clinical studies of IOPIDINE® 0.5% Ophthalmic Solution, the possibility of an additive or potentiating effect with CNS depressants (alcohol, barbiturates, opiates, sedatives, anesthetics) should be considered. 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 apraclonidine can lead to a reduction in IOP lowering effect. No data on the level of circulating catecholamines after apraclonidine withdrawal are available. Caution, however, is advised in patients taking tricyclic antidepressants which can affect the metabolism and uptake of circulating amines.
An additive hypotensive effect has been reported with the combination of systemic clonidine and neuroleptic therapy. Systemic clonidine may inhibit the production of catecholamines in response to insulin-induced hypoglycemia and mask the signs and symptoms of hypoglycemia.
Since apraclonidine may reduce pulse and blood pressure, caution in using drugs such as beta-blockers (ophthalmic and systemic), antihypertensives, and cardiac glycosides is advised. Patients using cardiovascular drugs concurrently with IOPIDINE 0.5% Ophthalmic Solution should have pulse and blood pressures frequently monitored. Caution should be exercised with simultaneous use of clonidine and other similar pharmacologic agents.
Iopidine Eye Contraindications
IOPIDINE 0.5% Ophthalmic Solution is contraindicated in patients with hypersensitivity to apraclonidine or any other component of this medication, as well as systemic clonidine. It is also contraindicated in patients receiving monoamine oxidase inhibitors (MAO inhibitors).
Additional information about Iopidine Eye
Iopidine Eye Indication: For short-term adjunctive therapy in patients on maximally tolerated medical therapy who require additional Intra Ocular Pressure (IOP) reduction.
Mechanism Of Action: Iopidine Eye is an alpha adrenergic receptor agonist. It has a peak ocular hypotensive effect occurring at two hours post-dosing. Fluorophotometric studies in animals and humans suggest that Iopidine Eye has a dual mechanism of action by reducing aqueous humor production and increasing uveoscleral outflow.

Absorption: Topical use of apraclonidine ophthalmic solution leads to systemic absorption. Studies of apraclonidine (0.5% ophthalmic solution) dosed one drop three times a day in both eyes for 10 days in normal volunteers yielded mean peak and trough concentrations of 0.9 ng/mL and 0.5 ng/mL, respectively.
Toxicity (Overdose): Accidental or intentional ingestion of oral apraclonidine has been reported to cause apnea, arrhythmias, asthenia, bradycardia, conduction defects, diminished or absent reflexes, dryness of the mouth, hypotension, hypothermia, hypoventilation, irritability, lethargy, miosis, pallor, respiratory depression, sedation or coma, seizure, somnolence, transient hypertension, and vomiting.
