PURPOSE: Analysis of local and systemic effects of RS-timolol enantiomer and S-timolol in patients with ocular hypertension and glaucoma: evaluation of risk/benefit ratio. MATERIAL AND METHODS: Nineteen patients (38 eyes) receiving 0.85% RS-timolol and ten patients (20 eyes) receiving 0.5% S-timolol were evaluated using a double-blind test. Intraocular pressure, heart rate, systemic arterial blood pressure, ECG and spirometry were recorded before and two hours after drug administration and after seven days of treatment. RESULTS: There were no statistically significant differences between the intraocular pressure-lowering effects of RS-timolol and S-timolol. In patients receiving both medicines, bradycardia was detected two hours after drug administration. Patients receiving RS-timolol showed increased expiratory capacity compared to those receiving S-timolol. There was no detectable influence of either medicine on ECG and systemic arterial blood pressure. CONCLUSIONS: 0.85% RS-timolol and 0.5% S-timolol produced comparable intraocular pressure-lowering effects. 0.85% RS-timolol had a less severe influence on the respiratory system. LA: Polish
