Short-term Efficacy and Safety of Omidenepag Isopropyl 0.002% w/v Therapy for Patients with Primary Open-angle Glaucoma and Ocular Hypertension

Purpose: To analyze the short-term efficacy and safety of omidenepag isopropyl 0.002% (w/v) in patients with primary open-angle glaucoma and ocular hypertension.Methods: Data on 36 patients with primary open-angle glaucoma and ocular hypertension treated with omidenepag isopropyl 0.002% (w/v) from January 2021 to May 2022 were retrospectively analyzed. We investigated whether the drug lowered the intraocular pressure (IOP) at 1 and 3 months compared to baseline. Possible side effects were sought at each visit.Results: The mean patient age was 59.2 years at the time of treatment. Of the 36 patients, 33 had primary open-angle glaucoma and 3 had ocular hypertension. The baseline IOP was 15.9 ± 3.6 mmHg, which significantly decreased to 13.7 ± 2.8 and 13.4 ± 2.9 mmHg at 1 and 3 months, respectively, following instillation of omidenepag isopropyl 0.002% (w/v) (both p < 0.01). Twelve patients (29.2%) experienced side effects including hyperemia, ocular pain, and itching but only two (5.5%) stopped using the medication.Conclusions: In the short-term, ominedepag isopropyl 0.002% (w/v) is effective and safe in patients with primary open-angle glaucoma and ocular hypertension.
