Patent number: 8092838Abstract: Topical administration of a generator of H2S in biological tissues for the treatment of eye disorders, such as glaucoma. NaHS caused a time-dependent decrease in intraocular pressure in normotensive, conscious albino rabbits indicating a similar role for H2S in the regulation of aqueous humor dynamics in animals and humans. H2S donors, NaHS and Na2S, inhibited field-stimulated [3H]NE release from porcine isolated iris-ciliary bodies and produced relaxation of pre-contracted iris muscle strips indicating a pharmacological role for H2S in the anterior uvea. The observation that donors of H2S can alter sympathetic neurotransmission and induce an inhibitory action on iris smooth muscle suggests that this gas has the potential to influence several physiological/pathological processes in the eye. The ability of NaHS or Na2S to inhibit [3H]NE release mimics the well-established action some antiglaucoma drugs (e.g.Type: GrantFiled: May 1, 2006Date of Patent: January 10, 2012Assignees: The University of Houston System, Board of Regents of the University of Nebraska, Creighton UniversityInventors: Sunny Edet Ohia, Catherine Atieno Opere, Guilin Zhan, Emmanuel Monjok, Kaustubh Kulkami, Ghislaine E.
