Timolol und Adrenalindipivalat bei der Behandlung des erh�hten intraocularen Druckes

Abstract

Twenty-seven patients with ocular hypertension or open angle glaucoma were tested to see if, and to what extent, timolol and dipivalyl-epinephrine produced a supplementary reduction of intraocular pressure. In a shortterm study, 14 patients were tested with timolol (0.1%) and dipivalyl-epinephrine (0.25%). Simultaneous application of both substances produced a statistically more significant reduction of intraocular pressure than either timolol (0.1%) or dipivalyl-epinephrine (0.25%) alone. In 13 patients a comparison was made between patients who received both timolol (0.25%) and dipivalyl-epinephrine (0.1%) bis x and patients who received only timolol (0.25%) bis x over a period of 6, 9 and 12 weeks. Both substances used in combination produced a statistically more significant reduction in intraocular pressure than timolol (0.25%) bis x alone. The simultaneous application of an alpha and beta-adrenergic agonist and beta-adrenergic antagonist is not contradictory. The results are discussed on the basis of the mode of action of the applied substances.
