Submicron loteprednol etabonate ophthalmic gel 0.38% for the treatment of inflammation and pain after cataract surgery
2018
Purpose 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. Setting Forty-five United States ophthalmology practices. Design Double-masked vehicle-controlled randomized parallel group study. Methods 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). Results 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 Conclusion 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.
