Comparative Study of Dorzotimol Eye Drops, 20 mg/mL + 5 mg/mL Versus Cosopt® Eye Drops, 20 mg/mL + 5 mg/mL

The goal of this study is to compare efficacy and safety of Dorzotimol eye drops, 20 mg/mL + 5 mg/mL manufactured by JADRAN-GALENSKI LABORATORIJ d.d. (Croatia) aimed at lowering elevated IOP in patients with ocular hypertension and primary open-angle glaucoma (POAG) versus Cosopt® eye drops, 20 mg/mL + 5 mg/mL manufactured by Laboratoires Merck Sharp \& Dohme-Chibret, France. The main questions it aims to answer are: * if the efficacy of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma is equal; * if the safety of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma is equal. A total of 110 participants were screened and randomized 1:1 to the investigational drug (Dorzotimol) group or the reference drug (Cosopt) group. 55 patients were recruited in each group. Researchers compared the investigational drug (Dorzotimol) group with the reference drug (Cosopt) group to see if the efficacy and safety of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma are equal.
