We retrospectively reviewed records of patients prescribed latanoprostene bunod 0.024% (LBN) to assess its efficacy and safety in a real-world clinical setting. LBN was efficacious in lowering intraocular pressure (IOP) and had a favorable safety profile.
Purpose:The aim of this study was to evaluate the usage of LBN, the first topical nitric oxide-donating prostaglandin analog (PGA) for reducing IOP, in clinical practice.Patients and Methods: Retrospective review identified patients prescribed LBN by 5 glaucoma specialists at an academic center from January 2018 to November 2019. Fifty-six patients (102 eyes) met inclusion criteria of an IOP measured at the visit LBN was prescribed and at 2 visits ≥ 7 days after beginning treatment, with no surgeries, lasers or medication changes during follow-up. Main outcome measures were IOP, number of ocular medications, and adverse effects.Results: IOP (mean ± SD, mm Hg) at the visit LBN was prescribed was 16.2 ± 4.3 on 3.2 ± 1.5 glaucoma medications. IOP at most recent visit was 13.7 ± 3.8 on 3.2 ± 1.6 medications. Mean IOP reduction was 2.1 ± 3.5 (P < 0.0001) at first follow-up, after 38.7 ± 36.5 days, and 2.5 ± 3.3 (P < 0.0001) at last follow-up, after 235.9 ± 160.8 days. Pressure decreased ≥ 2 mm Hg in 60%, ≥ 3 mm Hg in 46%, and ≥ 4 mm Hg in 34% of eyes. All patients received LBN as replacement for a PGA or latanoprost/netarsudil fixed-dose combination. Forty-three patients remained on LBN throughout the follow-up period. Seven were discontinued for insufficient pressure control, 4 for adverse effects including pain and itching, and 2 for financial reasons.
Conclusions:In 2 years of clinical use of LBN, patients exhibited IOP reductions that were statistically significant overall and clinically meaningful in 60% of patients. LBN was well-tolerated and may be more efficacious than traditional PGAs.
