Purpose: To compare the efficacy of loteprednol etabonate 0.5%/tobramycin 0.3% (LE/T) and dexamethasone 0.1%/tobramycin 0.3% (DM/T) ophthalmic suspensions in reducing select signs of blepharitis.
Methods: Data were pooled from two studies (one from the USA; one from China) of adults (n = 627) with blepharokeratoconjunctivitis treated with LE/T or DM/T four times daily for 2 weeks (safety population). Efficacy analyses included 495 eyes (247 LE/T, 248 DM/T) with any baseline sign of blepharitis.
Results: At Day 15, the least squares mean change from baseline in composite blepharitis severity was similar between LE/T (-2.86) and DM/T (-2.99) (90% CI for mean treatment difference: -0.35, 0.11). Intraocular pressure (IOP) increases ≥10 mmHg over baseline were reported for 1 US patient (DM/T group) and 19 Chinese patients (6 LE/T; 13 DM/T).
Conclusions: LE/T was similarly effective in reducing the signs of blepharitis compared with DM/T, but demonstrated a better safety profile with respect to changes in IOP.
