Claims
- 1. A method of treating animals of the mammalian species for glaucoma which comprises administering to the eye of a mammal having glaucoma a pharmaceutical composition comprising as its active ingredient one or more compounds having chloride channel blocking activity.
- 2. A method of claim 1 wherein the composition is an ophthalmic solution, adapted for administration to the eye of a mammal in the form of eye droplets.
- 3. The method of claim 2 wherein the compound having chloride channel blocking activity is present in the concentration range of 0.0001 to 1 per cent by volume.
- 4. The method of claim 1 wherein the compound having chloride channel blocking activity is selected from the group consisting of N-phenylanthranilic acid, DPC (diphenylamine-2-carboxylic acid), IAA-94 (R(+)methylindazone, indanyloxyacetic acid 94), 2-aminomethyl phenols, MK-447 (2-aminomethyl-4-(1,1-dimethyl ethyl)-6-iodophenol hydrochloride (2) disulfonic stilbenes and DIDS (4,4'-diisothiocyanostilbene-2-2'-disulfonic acid) and 5-nitro-2(3 phenyl propyl amino)-benzoate (NPPB).
- 5. The method of claim 1 wherein the compound having chloride channel blocking activity is selected from the group consisting of compounds represented by the formula: ##STR3## wherein R is hydrogen or a pharmaceutically-acceptable cation.
- 6. The method of claim 5 wherein R is hydrogen or an alkali metal ion or a quaternary amine selected from the group consisting of mono-, di- and trialkyl amines, wherein each alkyl group may comprise up to six carbon atoms, ethanolamine, or caffeine or tromethamine, or a lower alkyl radical having up to six carbon atoms.
- 7. The method of claim 6 where the composition is an ophthalmic solution, adapted for administration to the eye of a mammal in the form of eye droplets.
- 8. The method of claim 7 wherein the composition contains approximately 0.0001 to 1 per cent weight by volume of said compound having chloride channel blocking activity.
- 9. The method of claim 1 wherein the compound having chloride channel blocking activity is selected from the group consisting of MK-447 (2-aminomethyl-4-(1,1-dimethyl ethyl)-6-iodophenol and DIDS (4,4'-diisothiocyanostilbene-2-2'-disulfonic acid).
- 10. A method of treating animals of the mammalian species, including humans, for the purpose of reducing intraocular pressure in the eye of the mammal comprising the step of administering to the mammal a pharmaceutical composition which comprises as its active ingredient one or more compounds having chloride channel blocking activity.
- 11. The method of treatment of claim 10 where the composition is an ophthalmic solution adapted for administration to the eye of a mammal in the form of eye droplets.
- 12. The method of treatment of claim 11 wherein in the ophthalmic composition the concentration of the compound having chloride channel blocking activity is in the range of approximately 0.0001 to 1 per cent weight by volume.
