  • Patent number: 4902696
    Abstract: Herein is described an ocular composition comprising an ocular decongestant such as phenylephrine and certain labdane derivatives which are intraocular pressure lowering agents. The composition not only markedly reduces the ocular reddening otherwise produced by such labdane compounds, but also unexpectedly prolongs and frequently potentiates their intraocular pressure lowering effect. Both of these effects are very beneficial to the use of such labdanes for the treatment of glaucoma.
