Changes in the types and daily treatment costs of anti-glaucoma eye drops in China in recent 15 years

Abstract

Objective: To investigate the changes in the types of anti-glaucoma eye drops and daily treatment costs in 2021 compared with 2006 in China. Methods: The information of the main anti-glaucoma eye drops in 2021 was obtained from the database of Yaozhi.com. The daily cost of each eye drop was calculated by recording the number of drops in a single bottle and pricing in the national market, and the corresponding information of anti-glaucoma eye drops collected in 2006 was compared. Based on the income of Chinese residents in 2006 and 2021, the proportion of the daily cost of anti-glaucoma eye drops in the annual income of residents was analyzed. Results There were 32 kinds of anti-glaucoma eye drops in 2021, and the daily cost was 0.34 to 16.00 yuan. The daily cost is 0.34 to 6.77 yuan after removing the single-dose package. The number of drugs in 2021 was significantly higher than that in 2006 (16). In 2021, prostaglandins accounted for the highest proportion of 31.25%. There was a significant increase in the number of generic drugs, fixed formulations and preservative-free single-dose packages. In 2021, the price of imported drugs was significantly reduced, with the daily cost falling by 29.28% to 53.78% compared with 2006. In 2021, the daily cost of the most expensive drugs accounted for 12.32% and 30.85% of the daily income of urban and rural residents, respectively (5.21% and 13.05% after removing single-dose packaged drugs), which were significantly lower than 37.46% and 122.79% in 2006. Conclusions Compared with 2006, the variety of anti-glaucoma eye drops increased significantly in 2021, and the daily treatment cost and the proportion of daily income were significantly reduced.
