Trends in glaucoma drug prescriptions: U.S. ophthalmologists favor generics and newer agents
A recent study analyzing Medicare Part D data from 2018 to 2022 highlights shifting trends in glaucoma drug prescriptions by U.S. ophthalmologists. The findings indicate a temporary decline in claims from 2018-2019 to 2019-2020, likely influenced by the COVID-19 pandemic, followed by a subsequent rise in prescriptions through 2021-2022.
Prostaglandin analogs emerged as the most frequently prescribed drug class, with latanoprost, timolol, and the dorzolamide/timolol combination being the top choices. Generic medications dominated the market, with their usage steadily increasing over time. Rho kinase inhibitors represented the fastest-growing drug class, signaling a shift toward newer therapeutic options.
These prescribing patterns reflect the rising prevalence of glaucoma and evolving treatment preferences among ophthalmologists.
