  • Publication number: 20050130931
    Abstract: The present invention is directed to a method of reducing intraocular pressure. The method comprises administering to a subject a pharmaceutical composition comprising an effective amount of a nucleoside 5?-pyrophosphate pyranoside or analogue, which is defined by general Formula I. The method of the present invention is useful in the treatment or prevention of ocular hypertension, such as found in glaucoma, including primary and secondary glaucoma. The method can be used alone to reduce intraocular pressure. The method can also be used in conjunction with another therapeutic agent or adjunctive therapy commonly used to treat glaucoma to enhance the therapeutic effect of reducing the intraocular pressure. The present invention also provides a novel composition comprising a nucleoside 5?-pyrophosphate pyranoside or analogue.

  • Publication number: 20040198803
    Abstract: The present invention provides a method of reducing intraocular pressure by administering pharmaceutical compositions comprising indole derivatives. The pharmaceutical compositions useful in this invention comprise indole derivatives and melatonin analogs of Formulae I-IV. A preferred embodiment is a method of lowering intraocular pressure using 5-(methoxycarbonylamino)-N-acetyltryptamine (5-MCA-NAT), also known as GR 135531, which has a prolonged duration of action and greater efficacy in lowering intraocular pressure compared to melatonin. The present invention further provides a method of treating disorders associated with ocular hypertension, and a method of treating various forms of glaucoma; the method comprises administering an effective dose of a pharmacuetical composition comprising an indole derivative with or without agents commonly used to treat such disorders.
