Abstract
Improved artificial tear compositions are described. The compositions are preferably formulated as sterile, isotonic solutions. The solutions contain a unique combination of three demulcents. The solutions preferably also contain one or more electrolytes and may also contain a nonionic surfactant. The solutions provide ocular comfort and are particularly useful in patients that are experiencing mild to moderate dryness or other irritation of the cornea. The solutions may be packaged as either an unpreserved unit dose product or as a preserved multi-dose product. The multi-dose products contain a very mild antimicrobial preservative system, and consequently can be frequently applied to the eye with little risk of ocular irritation attributable to the preservative components.
