The intraocular pressure responses of low-dose bupranolol (Ophtorenin) and methazolamide (Neptazane) in glaucomatous eyes. A controlled clinical study. 1979

W Leydhecker, and G K Krieglstein

In a single-dose, double-blind study, the minimum effective doses of bupranolol and methazolamide were established. The beta-blocker bupranolol (Ophtorenin, Dr. Winzer, Konstanz) in an oily solution reduced IOP significantly in a concentration of 0.05%. The carboanhydrase inhibitor Methazolamide (Neptazane) did not change IOP in a peroral dose of 50 mg, while 100 mg p.o. gave a significant IOP decrease. Both drugs exhibited an additive effect in this low regimen. It is concluded that the combined application of both drugs will postpone or avoid side effects and prolong the time and the field of clinical usefulness. It appears possible that both have a different mechanism of action.

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
