[Effect of timolol-epinephrine combination on intraocular pressure (author's transl)]

There were no signs of incompatibility between timolol and epinephrine, administered simultaneously with other antiglaucoma drugs in 20 eyes. A drop in IOP, related to the addition of epinephrine to previous antiglaucoma therapy was noted. The sites of beta-blockade and beta-stimulation have not yet been determined.
