PURPOSE: To evaluate omidenepag isopropyl (OMDI) for its efficacy in intraocular pressure control (IOP) and adverse reactions following administrations in Japanese patients with open-angle glaucoma (OAG) over a 3-month period. STUDY DESIGN: Retrospective observational study. SUBJECTS AND METHODS: Group 1 included untreated OAG patients, Group 2 included OAG patients treated with prostaglandin F (FP) receptor agonists (monotherapy) and Group 3 included OAG patients treated with multidrug therapy, including FP receptor agonists. OMDI was newly administered in Group 1, and FP receptor agonists were switched to OMDI in Group 2. In Group 3, all other ocular hypotensive medications were continued except FP receptor agonists. IOP changes were examined, and adverse reactions were retrieved from the medical records. RESULTS: Group 1 included 32 eyes, Group 2, 20 eyes and Group 3, 17 eyes. In Group 1, the baseline IOP was 15.7 mmHg (95% confidence interval [CI] 14.7-16.8 mmHg). After eyedrop treatment, the IOP was 14.1 mmHg (P < 0.001) at 1 month and 13.7 mmHg (P < 0.001) at 3 months. By contrast, in Group 2 and Group 3, switching FP receptor agonists to OMDI did not result in significant IOP changes (P ≥ 0.71). Six patients developed adverse reactions (hyperemia, headache, ocular pain, and swollen eyelids). CONCLUSIONS: New administration of OMDI significantly reduced the IOP. Furthermore, the IOP did not change after switching from FP receptor agonists to OMDI, including multidrug therapy. OMDI can be used as a first-line drug and is comparable to FP receptor agonists in Japanese patients with OAG.
