Review of Azithromycin Ophthalmic 1% Solution (AzaSite(®)) for the Treatment of Ocular Infections.

ABSTRACT: AzaSite(®) (azithromomycin 1.0%) ophthalmic solution was approved in 2007 by the US Food and Drug Administration (FDA) as the first commercially available formulation of ophthalmic azithromycin for the treatment of bacterial conjunctivitis. AzaSite(®) utilizes a vehicle delivery system called DuraSite(®), which stabilizes and sustains the release of azithromycin to the ocular surface, leading to a longer drug residence time, less frequent dosing, and an increase in patient compliance. AzaSite(®) is a broad spectrum antibiotic, effective against Gram-positive, Gram-negative, and atypical bacteria. AzaSite(®) has been studied for the treatment of ocular conditions beyond its clinical indication. A number of clinical studies have evaluated its efficacy and safety in the management of ocular conditions such as bacterial conjunctivitis and blepharitis on both the pediatric and adult populations. This article aims to evaluate the peer-reviewed published literature on the use of azithromycin 1.0% ophthalmic for current and possible future ophthalmic uses.

Project description:SignificanceThe α2-adrenergic receptor agonist brimonidine has been reported to induce conjunctival blanching in cataract, strabismus, laser refractive, and filtration procedures. Clinicians are often faced with red eyes with no apparent underlying pathology. Low-dose brimonidine reduced ocular redness in such subjects with efficacy maintained over 1 month and negligible rebound redness.PurposeThe aim of this study was to evaluate the safety and efficacy of brimonidine tartrate ophthalmic solution 0.025% for the treatment of ocular redness.MethodsIn this single-center, double-masked, phase 3 clinical trial, adult subjects with baseline redness of more than 1 unit in both eyes (0- to 4-unit scale) were randomized 2:1 to brimonidine 0.025% or vehicle. A single dose was administered in-office (day 1); thereafter subjects instilled treatment four times a day for 4 weeks, with clinic visits on days 15, 29, and 36 (7 days post-treatment). Efficacy end points included investigator-evaluated redness 5 to 240 minutes post-instillation on day 1 (primary); investigator-evaluated change from baseline 1, 360, and 480 minutes post-instillation on day 1, and 1 and 5 minutes post-instillation on days 15 and 29; total clearance of redness, and subject-assessed redness. Safety/tolerability measures included adverse events, rebound redness, and drop comfort.ResultsSixty subjects were randomized (n = 40 brimonidine, n = 20 vehicle). Investigator-assessed redness was lower with brimonidine versus vehicle over the 5- to 240-minute post-instillation period (mean [SE], 0.62 [0.076] vs. 1.49 [0.108]; P < .0001) and at each time point within that period (P < .0001). At 1, 360, and 480 minutes post-instillation, respectively, the mean differences (95% confidence interval) between treatments were -0.73 (-1.05 to -0.41), -0.57 (-0.84 to -0.29), and -0.39 (-0.67 to -0.10), respectively. No tachyphylaxis was evident with brimonidine on days 15 and 29, and minimal rebound redness was observed following discontinuation. Adverse events were infrequent, and brimonidine was rated as very comfortable.ConclusionsBrimonidine 0.025% appeared safe and effective for reduction of ocular redness, with an 8-hour duration of action, no evidence of tachyphylaxis, and negligible rebound redness.

Project description:BackgroundDry eye disease (DED) is a disorder characterized by loss of tear film homeostasis that causes ocular surface inflammation and damage. The incidence of DED increases with age. Cyclosporine ophthalmic solution 0.09% (CEQUA®; OTX-101), cyclosporine ophthalmic emulsion 0.05% (Restasis®; CsA), and lifitegrast ophthalmic solution 5% (Xiidra®; LFT) are anti-inflammatory agents indicated for DED. This analysis compared treatment patterns in patients with DED receiving OTX-101, CsA, or LFT.MethodsThis real-world, retrospective, longitudinal cohort study utilized Symphony Health Integrated Dataverse claims from July 2019 to June 2021. The dataset included all patients with OTX-101 claims and patients with CsA or LFT claims randomly selected 2:1 to OTX-101. Patients were sorted into 3 cohorts based on index treatment. Index date was that of first treatment claim, and follow-up period was from index date to end of clinical activity or data availability. Time to treatment discontinuation (TTD), probability of discontinuation, and treatment persistence were assessed for OTX-101 vs. CsA, then OTX-101 vs. LFT. Subgroup analysis was performed based on age and prior DED treatment. Kaplan-Meier analysis and log-rank test were used to examine TTD. A logistic model evaluated association between index treatment and discontinuation. Unadjusted and adjusted odds ratios, 95% confidence intervals, and P-values were reported, with statistically significant associations based on P-values < 0.05.ResultsOverall, 7102 patients (OTX-101 n = 1846; CsA n = 2248; LFT n = 3008) were eligible. Median TTD was 354 days for patients receiving OTX-101 vs. 241 days for CsA and 269 days for LFT. Log-rank test indicated TTD was significantly longer for patients on OTX-101 vs. CsA (P = 0.033). Patients on CsA were 35% more likely to discontinue treatment than patients on OTX-101; OTX-101 and LFT groups had similar discontinuation rates. After 360 days, 49.8% of patients receiving OTX-101 remained on treatment vs. 39.4% of patients on CsA (P = 0.036) and 44.0% of patients on LFT (P = 0.854).ConclusionsPatients receiving OTX-101 remained on treatment significantly longer and were significantly less likely to discontinue treatment than patients on CsA. Older patients remained on OTX-101 significantly longer than CsA. These findings highlight treatment pattern differences in patients with DED receiving these anti-inflammatory agents.
