Combinations of preservatives for ophthalmic compositions |
| abstract |
The present invention provides a preservative composition for protecting ophthalmic solutions from microbial attack comprising a combination of benzalkonium ion and polyhexamethylene biguanide (PHMB) wherein the combined concentrations of benzalkonium ion and polyhexamethylene biguanide (PHMB) in said composition is sufficient to provide protection against microbial attack when said composition is added to an ophtalmic solution as compared to said ophthalmic soulution having the same concentration of benzalkonium ion and polyhexamethylene biguanide (PHMB), alone. |
