Abstract
PURPOSE: This retrospective chart review of netarsudil (Rhopressa) characterizes intra-ocular pressure (IOP) reduction, drug tolerance, drug cost, and compliance in a tertiary university Midwest clinic in a variety of glaucoma diagnoses on patients prescribed netarsudil 01/2017 to 5/2020. METHODS: Patient demographics, primary diagnosis, indication for medication, prescription date, prescription fill status, duration of use, discontinuation reason, and number of IOP-lowering medications were noted. Confounding medication changes were excluded from IOP analysis. The IOP difference between the first visit after starting netarsudil and the baseline (mean before starting netarsudil on the stable medication regimen) was calculated. RESULTS: A total of 133 patients were prescribed netarsudil (age 69 ± 20 years, 59% females, 79% white, 86% primary glaucoma) as adjunct glaucoma medication (mean medications 3.2 ± 0.9). Indications were lowering IOP (mean baseline IOP 20.0 ± 6 mmHg) and drug regimen simplification. Prescription was not filled by 22/133 subjects because of the cost (68%) and the need for surgery (23%). No demographic factors were associated with prescription fill status. A total of 101 eyes of 76 patients were used for IOP analysis. The mean change in IOP was -0.8 ± 6.4 mmHg, (IOP decrease in 67%, increase or no change in 33% eyes). Netarsudil was discontinued in 52% (50/96) patients; the reasons include surgery for IOP control (42%), allergies (30%), cost (14%), and paradoxical rise in IOP (12%). CONCLUSION: Netarsudil was used as adjunct third or fourth line medication at a glaucoma practice in Midwestern USA. 17% of prescriptions went unfilled; netarsudil was discontinued in 52% of patients. IOP response was variable in this population with severe complex glaucoma.
