ABSTRACT Glaucoma is a disease that affects a large part of the population and represents the main reason for total vision loss. As part of the first-line treatment of this pathology, two fast-acting drugs are used, Dorzolamide and Timolol. This report aims to compare the results of the stability study of a Timolol ophthalmic solution and a Dorzolamide ophthalmic solution whose duration was 36 months with storage at 30°C ± 2°C and a relative humidity of 35% ± 5%. The solutions were analyzed in the stages of 6, 12, 24 and 36 months. Appearance, volume, pH and titration were analyzed, which was carried out using high- efficiency liquid chromatography (HPLC) analysis. Dorzolamide ophthalmic solution began the study with a description of a colorless, transparent, slightly viscous solution. Free of visible particles; pH of 5.62; volume 5.2 mL and titration 100.5%. At the end of the study there was only a variation in pH (0.06); volume (0.1 mL) and the assessment ended with a value of 99.5%, having a reduction of 1%. Timolol ophthalmic solution began the study with a description of a colorless, clear solution. Free of visible particles; pH 6.63; volume 5.2 mL and titration of 102.2%. At the end of the study there was a variation in pH (0.1); volume (0.2 mL) and the assessment ended with a value of 98.2%, having a reduction of 4%.
