Which drugs does patent 8,388,941 protect, and when does it expire?
| Title: | Self preserved aqueous pharmaceutical compositions |
| Abstract: | The use of a borate/polyol and zinc system to enhance the antimicrobial activity of multi-dose pharmaceutical compositions is described. The compositions do not require a conventional anti-microbial preservative and therefore are referred to as being `self-preserved`. The compositions possess sufficient antimicrobial activity to satisfy the preservative efficacy requirements of the USP for aqueous ophthalmic compositions. |
