Alcon has filed a patent for an ophthalmic composition that delivers drugs using artificial tears. The composition includes galactomannan, a buffering agent, and a cis-diol, and is free of borate. The formulation has an osmolality between 240 mOsm/kg and 110 mOsm/kg. The galactomannan concentration is between 0.16 w/v % and 0.19 w/v %, the buffering agent concentration is between 0.1 w/v % and 0.2 w/v %, and the cis-diol concentration is between 0.5 w/v % and 5.0 w/v %. The galactomannan options include guar, hydroxylpropyl guar, and combinations thereof. The buffering agent includes a bis-aminopolyol of formula (I) or a salt thereof.

A recently filed patent (Publication Number: US20230310615A1) describes an ophthalmic composition that is free of borate and includes a galactomannan, a buffering agent, and a cis-diol. The galactomannan, such as guar or hydroxylpropyl guar, is present at a concentration of 0.16% to 0.19%, while the buffering agent is present at a concentration of 0.1% to 0.2%. The cis-diol, specifically sorbitol, is present at a concentration of 0.5% to 5.0%. The composition also includes at least one demulcent, such as glycerin, polyvinyl pyrrolidone, or propylene glycol. Propylene glycol and polyethylene glycol 400 are specifically mentioned as demulcents in this patent. The pH value of the composition is between 6.5 and 8.5. The ophthalmic composition may also include an anesthetic drug, glaucoma therapeutics, pain reliever, anti-hypertensive agent, neuro-protective agent, muco-secretagogue, angiostatic agent, anti-angiogenesis agent, growth factor, immunosuppressant agent, anti-infective agent, antiviral agent, anti-inflammatory agent, anti-myopia agent, anti-allergy agent, dopaminergic antagonist, protein, anti-microbial, cooling agent, antioxidant, nutriceutical, omega-3 fatty acid, omega-6 fatty acid, vitamin A, vitamin D, vitamin E, tocopherols, vitamin K, beta-carotene, or combinations thereof. The ophthalmic composition has an osmolality in the range of 220 mOsm/kg to 170 mOsm/kg or 215 mOsm/kg to 190 mOsm/kg. It contains less than 0.1% W/V of borate and no preservative.
Additionally, the patent describes an ophthalmic emulsion that includes water forming an aqueous phase, oil forming an oil phase, a hydrophilic surfactant with an HLB value of 10 to 18, a hydrophobic surfactant with an HLB value of 1 to 6, a charged phospholipid, a mucoadhesive galactomannan polymer, a cis-diol, and a bis-aminopolyol of formula (I) or a salt thereof.
This patent presents a novel ophthalmic composition that is free of borate and includes specific concentrations of galactomannan, buffering agent, and cis-diol. The composition may also include various demulcents and other active ingredients. The pH value and osmolality of the composition are within specific ranges. The patent also describes an ophthalmic emulsion with specific components. This invention has the potential to provide improved ophthalmic formulations for various applications, including drug delivery and treatment of eye conditions.
