loteprednol-etabonate and Eye-Pain

The safety of KPI-121 0.25%, an ophthalmic nanoparticle suspension of loteprednol etabonate, was evaluated in subjects with dry eye disease (DED) in one phase 2 and three phase 3 randomized trials of similar design.. Adults with DED received KPI-121 0.25% or vehicle drops 4 times daily (QID) for ≥2 weeks; 1430 subjects received KPI-121 0.25% and 1438 subjects received vehicle drops. Main safety assessments were adverse events (AEs) and intraocular pressure (IOP). As a common side effect associated with the use of ocular corticosteroids is elevated IOP, subjects with a history of or current diagnosis of glaucoma were excluded.. Instillation site pain was the most common AE, reported by 5.2% of subjects in the KPI-121 0.25% group and 4.4% of subjects in the vehicle group; other AEs were reported by ≤0.8% of subjects in the KPI-121 group. IOP elevations, a side effect associated with the use of ophthalmic corticosteroids, were observed with low incidence: 0.6% and 0.2% of subjects in the KPI-121 and vehicle groups, respectively. An IOP elevation was defined as an increase from baseline of >5 mm Hg that resulted in an IOP of ≥21 mm Hg in either eye during use of the study product.. KPI-121 ophthalmic suspension 0.25% seemed to be safe and well tolerated when dosed QID for 2 to 4 weeks in those DED subjects included in the 4 trials.

To assess the safety and efficacy of a 0.38% submicron formulation of loteprednol etabonate (LE) gel for the treatment of postoperative inflammation and pain after cataract surgery.. Forty-five United States ophthalmology practices.. Double-masked vehicle-controlled randomized parallel group study.. Patients 18 years of age or older with anterior chamber cells grade 2 or higher on day 1 after uncomplicated cataract surgery were randomized to 14 days of treatment with LE gel 2 times a day, LE gel 3 times a day, or vehicle. Hierarchical primary endpoints were the proportion of patients with resolution of anterior chamber cells and grade 0 (no) pain at postoperative day 8. Safety outcomes included adverse events, intraocular pressure (IOP), biomicroscopy, visual acuity, ophthalmoscopy, and tolerability (drop comfort and ocular symptoms).. The intent-to-treat population included 514 patients. Significantly more patients in the LE gel 2 times a day and 3 times a day groups compared with the vehicle group had complete resolution of anterior chamber cells (26.9% and 28.7% versus 9.3%) and reported grade 0 pain (73.7% and 73.1% versus 47.7%) on day 8 (P < .001 vs vehicle for all). The safety findings were unremarkable, with 1 patient experiencing an IOP increase of 10 mm Hg or higher while on LE gel. More than 75% of patients in each group reported no drop discomfort.. In this study, submicron loteprednol etabonate gel 0.38% appeared safe and effective in the treatment of postoperative inflammation and pain whether instilled 2 times or 3 times a day.

To examine the efficacy and safety of a new gel formulation loteprednol etabonate 0.5% in the treatment of inflammation and pain after cataract surgery.. Seventeen United States clinical sites.. Prospective double-masked parallel-group study.. Patients with anterior chamber cell (ACC) grade 2 or higher after cataract surgery were randomized to loteprednol etabonate 0.5% gel or vehicle 4 times a day for 14 days. Primary outcome measures included the proportion of patients with complete resolution of ACC and grade 0 (no) pain on postoperative day 8. Safety measures included adverse events, intraocular pressure (IOP), visual acuity, biomicroscopy and funduscopy findings, and tolerability (ocular symptoms and drop comfort).. The intent-to-treat population included 406 patients (203 per treatment). On day 8, 30.5% of patients in the loteprednol etabonate group and 16.3% of patients in the vehicle group had complete resolution of ACC, whereas 72.9% and 41.9%, respectively, had grade 0 pain (both P<.001). Significant treatment differences for complete resolution of ACC and grade 0 pain favoring loteprednol etabonate were also found on day 15 and day 18. One patient in each treatment group had a significant increase in IOP (≥ 10 mm Hg). Analyses of pain, photophobia, and tearing favored loteprednol etabonate at different time points beginning on day 3. More than 85% of patients in each treatment group reported no discomfort on drop instillation.. Loteprednol etabonate gel 0.5% was efficacious and safe in treating postoperative inflammation and pain..

Topical ophthalmic corticosteroids are of clinical benefit in the management of pain and inflammation after ocular surgery; however, their use can be associated with class-associated adverse events (AEs) and limited bioavailability. Selection of an appropriate topical corticosteroid depends on drug-specific variables such as AE profile, efficacy, potency, dosing, patient-specific administration needs, and formulation properties aimed at minimizing precorneal drug loss, increasing ocular surface drug residence time, and maximizing drug delivery to the anterior tissues. Recently, strategies for improving ocular penetration of ophthalmic formulations have included use of mucoadhesive formulations (ie, polycarbophil-containing gels) and drug particle size reduction, enabling faster drug dissolution and therefore increased bioavailability and penetration. Loteprednol etabonate (LE) is a carbon-20 ester corticosteroid developed through retrometabolic drug design with potent anti-inflammatory effects and a reduced propensity for eliciting corticosteroid class AEs. This drug has been formulated for topical ophthalmic use after surgery as 0.5% and 1% suspensions, a 0.5% ointment, and a 0.5% gel. Preclinical and clinical data for a new 0.38% LE gel will be reviewed demonstrating that reducing the drug particle size to the nanometer range in diameter provides effective ocular tissue penetration and resolution of pain and inflammation despite a reduced drug concentration (0.38%) and dosing frequency.

This retrospective, clinical comparative analysis describes differences in clinical signs and symptoms and medication tolerability between those patients who receive topical corticosteroids prior to initiation of topical cyclosporine 0.5% emulsion (tCSA) therapy for chronic dry eye disease (CDED) and those who received tCSA and were not first induced with corticosteroid drops. tCSA is the only approved medication for CDED. Stinging is the most common side effect of tCSA and reason for tCSA discontinuation. This analysis describes an effective pharmacologic means to reduce tCSA stinging and subsequent discontinuation.. Thirty-six consecutive patients were initially treated with loteprednol etabonate (LE) 0.5% (Lotemax; Bausch & Lomb) for a period ranging from 2 to 16 months prior to institution of concomitant tCSA (Restasis™; Allergan). Clinical parameters (fluorescein staining, conjunctival redness, tear meniscus) were compared over a period of 6 months to a second cohort of 36 consecutive patients who were initially prescribed continuous tCSA without concomitant LE pretreatment. Patients in the LE pretreatment group discontinued LE after 3-6 months of concomitant therapy while continuing tCSA therapy.. Of the 36 LE pretreatment patients, only 2 developed significant stinging (5.5%) and 1 discontinued the use of tCSA because of stinging (2.8%). Of the patients without LE pretreatment, 8 developed stinging (22%) and 3 discontinued tCSA as a result (8.3%). The intergroup P value was significant for severe stinging (<0.02) and for tCSA discontinuation because of severe stinging (<0.04). Patients in the LE pretreatment group had no statistically significant differences in preenrollment disease severity or demographics (P range from 0.19 to 0.59) compared with the group without pretreatment.. Topical corticosteroid preparation of the ocular surface in CDED with LE induction therapy may reduce discomfort from subsequent long-term maintenance topical medications, particularly tCSA. This analysis describes a readily available induction and maintenance pharmacologic strategy to reduce tCSA stinging and subsequent discontinuation.
