[Topical oxpernolol in the treatment of various forms of glaucoma (author's transl)].

Oxprenolol is a new beta-adrenergic blocking drug, whose effectiveness in the treatment of various forms of glaucoma has been evaluated. The drug was administered topically as 0.5% -1%-2% solution. The results of the investigation may be summarized as follows: The instillation of the drug produces a transient and slight conjunctival hyperaemia and a not significant miosis. A significnat ocular hypotensive action has been observed in the treatment of chronic open-angle, hemorrhagic and congenital glaumiosis. A significnat ocular hypotensive action has been observed in the treatment of chronic open-angle, hemorrhagic and congenital glaucoma. The concentration of 0.5% Oxprenolol seems to be as effective as topical 1% Propranolol. At the same concentration (0.5%), Oxprenolol produces no significnat change of the systemic blood pressure or of the heart rate. Topical pre-treatment with 1% Oxprenolol inhibits the systemic side-effects (tachycardia) produced by topical Isoproterenol, a wellknown ocular hypotensive drug. The authors conclude the investigation affirming that Oxprenolol may represent a new effective means for the medical treatment of glaucoma.
