Abstract
A container, composition and method for preserving treatment solutions, in which the composition includes weak and strong preservatives. The dispensing container includes media within a dispensing tip which media removes or alters the strong preservative, while allowing the weak preservative to inhibit microbial growth in the tip media. The dispensing container is especially useful in delivering to the ocular environment ophthalmic solutions which are essentially free of strong preservative which may cause patient discomfort. A dispensing container including a pH-preserved pilocarpine solution is disclosed in one embodiment.
