Objectives. This study presents the use and trends of use of topical ocular anti-infectives into a European population in the current decade (2015 to 2019) with an analysis of concomitant use with other ocular drugs, considering distribution by age and gender.
Patients and Methods. A population-based registry study was carried out to assess the ocular anti-infectives use from 2015 to 2019. All dispensations of these medicines at pharmacies in the largest region of Spain, Castile and León, was accessed. The number of packages dispensed, the percentage of the population under treatment, diagnosis, and the concomitant use with other ocular medicines was observed. For all analyses, the population distribution by age and gender was considered.
Results. An average of 198,000 packages of topical ocular anti-infectives were dispensed annually to 5.38% of the population, and more commonly for women than for men (5.83% vs. 4.91%). Children and the elderly used more these medicines. Tobramycin, alone or in combination, accounted for more than 68% of the total consumption (135,000 packages per year), and was the most widely used anti-infective in almost all identified diagnoses. Conjunctivitis (50.12%), and stye (11.51%) were the most frequent diagnoses. The consumption of ocular anti-infectives increased by 8.23% from 2015 to 2019, and more among men than in women.
Conclusions. Our findings show that the most used topical ocular anti-infective was tobramycin, in accordance with the clinical practice guidelines recommendations. However, ocular infections are sometimes treated empirically, especially conjunctivitis.
