IOPIDINE® 0.5% Ophthalmic Solution contains apraclonidine hydrochloride, an alpha adrenergic agonist, in a sterile isotonic solution for topical application to the eye. Apraclonidine hydrochloride is a white to off-white powder and is highly soluble in water.
IOPIDINE 0.5% Ophthalmic Solution is indicated for short-term adjunctive therapy in patients on maximally tolerated medical therapy who require additional IOP reduction. Patients on maximally tolerated medical therapy who are treated with IOPIDINE 0.5% Ophthalmic Solution to delay surgery should have frequent followup examinations and treatment should be discontinued if the intraocular pressure rises significantly.
The addition of IOPIDINE 0.5% Ophthalmic Solution to patients already using two aqueous suppressing drugs (i.e., beta-blocker plus carbonic anhydrase inhibitor) as part of their maximally tolerated medical therapy may not provide additional benefit. This is because IOPIDINE 0.5% Ophthalmic Solution is an aqueous suppressing drug and the addition of a third aqueous suppressant may not significantly reduce IOP.
The IOP lowering efficacy of IOPIDINE 0.5% Ophthalmic Solution diminishes over time in some patients. This loss of effect, or tachyphylaxis, appears to be an individual occurrence with a variable time of onset and should be closely monitored. The benefit for most patients is less than one month.
Published Studies Related to Iopidine (Apraclonidine Ophthalmic)
Brinzolamide 1% versus apraclonidine 0.5% to prevent intraocular pressure elevation after neodymium:YAG laser posterior capsulotomy. [2006.09]
PURPOSE: To compare the efficacy of brinzolamide 1% with that of apraclonidine 0.5% in preventing intraocular pressure (IOP) rise after neodymium:YAG (Nd:YAG) laser posterior capsulotomy. SETTING: Department of Ophthalmology, Akdeniz University, Antalya, Turkey... CONCLUSION: Brinzolamide 1% and apraclonidine 0.5% given prophylactically before Nd:YAG laser capsulotomy were effective in preventing IOP spikes after treatment.
Comparing efficacies of 0.5% apraclonidine with 4% cocaine in the diagnosis of horner syndrome in pediatric patients. [2006.06]
PURPOSE: The aim of this study was to compare the efficacy of 0.5% apraclonidine with that of 4% cocaine and to evaluate its safety in the diagnosis of Horner syndrome in pediatric patients... CONCLUSIONS: The application of 0.5% apraclonidine in pediatric patients is safe and effective in the diagnosis of Horner syndrome.
Comparative efficacy of acetazolamide and apraclonidine in the control of intraocular pressure following phacoemulsification. 
PURPOSE: The purpose of our study was to compare the effects of systemically administered acetazolamide and topical apraclonidine 0.5% in the control of intraocular pressure (IOP) following phacoemulsification of senile cataracts. SETTING: The study was conducted on patients affected by cataract and followed at the Department of Ophthalmology... CONCLUSIONS: Our double-blind prospective study conducted on patients randomly assigned to treatment with apraclonidine or acetazolamide shows that the former drug is undoubtedly effective in the prevention of IOP increases following phacoemulsification. IOPs recorded in patients treated with this drug were lower than those observed in the acetazolamide and the control groups. Considering the lower risk of toxicity associated with topical administration, apraclonidine 0.5% seems to be preferable to oral acetazolamide in this postoperative setting. Copyright 2006 S.

Effect of apraclonidine versus dorzolamide on intraocular pressure after phacoemulsification. [2005.11]
BACKGROUND AND OBJECTIVE: To investigate the efficacy of 1% apraclonidine hydrochloride and 2% dorzolamide hydrochloride in controlling postoperative intraocular pressure elevation in patients undergoing phacoemulsification... CONCLUSION: Uneventful phacoemulsification involving meticulous cortical and viscoelastic removal does not cause a significant increase in intraocular pressure 24 hours following surgery.
Brimonidine 0.15% versus apraclonidine 0.5% for prevention of intraocular pressure elevation after anterior segment laser surgery. [2005.09]
PURPOSE: To compare the efficacy and safety of brimonidine 0.15% with those of apraclonidine 0.5% in preventing intraocular pressure (IOP) elevations after anterior segment laser surgery. SETTING: Massachusetts Eye and Ear Infirmary, Glaucoma Service, Boston, Massachusetts, USA... CONCLUSION: A single preoperative drop of brimonidine 0.15% had similar efficacy and safety as apraclonidine 0.5% in preventing IOP elevations immediately after anterior segment laser surgery.

Comparison of the Alpha-2 Agonists for Prevention of Intraocular Pressure Elevation After Selective Laser Trabeculoplasty [Recruiting]
The purpose of the study is to compare the safety and efficacy of two drops used to lower
eye pressure when given prior to a glaucoma laser procedure.
Impact Post-operative Treatment on Intraocular Pressure Post-SLT on Patients With Primary Open-angle Glaucoma [Recruiting]
The present study's main objective is to assess if there is a significant difference between
either of the treatments frequently used in post-op, namely a topic cortisone-based
treatment, an non-steroidal anti-inflammatory drug (NSAID) or simply a placebo, in order to
gain the best long term (6 months) efficacy of the SLT.
