OPHTHALMIC COMPOSITIONS WITH IMPROVED DESSICATION PROTECTION AND RETENTION
The present invention relates to artificial tear compositions and ophthalmic compositions suitable for drug delivery. In one embodiment of the present invention, the compositions comprise a galactomannan polymer such as guar or hydroxypropyl guar, hyaluronic acid, and a cis-diol such as sorbitol. In a preferred embodiment, the compositions also comprise a borate compound.
1 . An ophthalmic composition comprising 0.1 to 0.2 w/v % galactomannan, 0.05 to 0.5 w/v % hyaluronic acid, and 1.0 to 2.0 w/v % cis-diol.
2 . A composition according to claim 1 comprising 0.17 to 0.18 w/v % guar, 0.13 to 0.17 w/v % sodium hyaluronate, and 1.4 w/v % sorbitol.
3 . A composition according to claim 1 wherein said galactomannan is selected from the group consisting of:
guar, hydroxylpropyl guar, and combinations thereof.
4 . A composition according to claim 1 wherein said cis-diol is selected from the group consisting of sorbitol, mannitol, polyethylene glycols, polypropylene glycols, polyethyleneoxide-polybutyleneoxide block copolymers, and combinations thereof.
5 . A composition according to claim 1 wherein said cis-diol is sorbitol or mannitol.
6 . A composition according to claim 5 wherein said cis-diol is present at a concentration of about 1.4 w/v %.
7 . A composition according to claim 1 wherein said borate is boric acid.
8 . A composition according to claim 1 further comprising a demulcent selected from the group consisting of:
glycerin, polyvinyl pyrrolidone, polyethylene oxide, polyethylene glycol, propylene glycol, polyacrylic acid, and combinations thereof.
9 . A composition according to claim 8 wherein said demulcent is polypropylene glycol or polyethylene glycol.
10 . A composition according to claim 1 further comprising a pharmaceutically active compound.
11 . A method for treating ophthalmic disease which comprises administering to a subject in need of such treatment a composition according to claim 1 .
12 . A method according to claim 10 , wherein the ophthalmic disease is dry eye.
