    摘要: The present invention relates to viscosity stabilized ophthalmic formulations and ophthalmic formulations suitable for drug delivery. The formulations comprise galactomannans such as guar or hydroxypropyl guar and a borate source such as boric acid. The formulations further comprise a diol alcohol such as sorbitol and, optionally, a pharmaceutically acceptable divalent cation salt such as magnesium chloride.

    摘要: The present invention is an aqueous pharmaceutical composition that includes an ionized therapeutic agent, an ionic component and guar gum. The guar gum is present in the composition a concentration sufficient to limit interactions between the ionized therapeutic agent and the ionic component thereby imparting stability to the composition. The composition is preferably at or near physiologic pH. The aqueous pharmaceutical composition has been found particularly useful as an aqueous ophthalmic, otic or nasal composition. The pharmaceutical composition, due to its characteristics, is particularly suitable as an ophthalmic composition.

    摘要: The use of poly(oxybutylene)-poly(oxyethylene)-poly(oxybutylene) block copolymers in pharmaceutical compositions useful for modifying the surfaces of contact lenses and other medical devices is disclosed. The present invention is based in-part on a discovery that this class of compounds is particularly efficient in wetting hydrophobic surfaces, such as the surfaces of silicone hydrogel contact lenses and other types of ophthalmic lenses, but do not induce foaming when used in conjunction with a peroxide-based contact lens disinfection regimen. Such compounds may also be useful for cleaning purposes. The use of the compounds as surfactants in peroxide-based compositions for disinfecting contact lenses therefore represents a preferred embodiment of the present invention.

    摘要: The present invention relates to artificial tear formulations and ophthalmic formulations suitable for drug delivery. The formulations comprise galactomannans such as guar or hydroxypropyl guar and a borate source such as boric acid. The formulations further comprise a cis-diol such as sorbitol that interferes with the cross-linking of galactomannan and borate. Optionally, the formulations are substantially free of divalent cations.
