  • Use of nanoparticles as carriers for biocides in ophthalmic compositions
    Patent number: 8097270
    Abstract: The use of nanoparticles of inorganic materials (e.g., synthetic smectite clays) in ophthalmic compositions is described. The nanoparticles are utilized as biologically inert carriers or depots for biocides. The nanoparticles are particularly useful in preventing or reducing the uptake of biocides from ophthalmic compositions by contact lenses, when the compositions are applied to the lenses.
    Type: Grant
    Filed: December 20, 2002
    Date of Patent: January 17, 2012
    Assignee: Novartis AG

  • OPHTHALMIC SOLUTIONS WITH IMPROVED DISINFECTION PROFILES
    Publication number: 20110151017
    Abstract: The present invention relates to ophthalmic solutions with antimicrobial activity. The solutions have an antimicrobial compound such as hydrogen peroxide and a boron compound. In one embodiment, the solutions contain a boron compound such as sodium borate that provides antimicrobial activity in addition to that of hydrogen peroxide, particularly during periods following disinfection and neutralization of such solutions. This additional activity reduces the likelihood of microbial growth in contact lens disinfection applications that neutralize hydrogen peroxide.

  • Use of bis-amines to enhance the antimicrobial activity of aqueous compositions
    Patent number: 7871602
    Abstract: The use of bis-amines to enhance the antimicrobial activity of pharmaceutical compositions is described. The bis-amines are particularly useful for enhancing the antimicrobial activity of aqueous ophthalmic compositions, such as artificial tears or ocular lubricants, and solutions for disinfecting contact lenses.

  • N-HALAMINE FORMULATIONS WITH ENHANCED ANTIMICROBIAL ACTIVITY
    Publication number: 20100303930
    Abstract: The present invention relates to antimicrobial formulations comprising an N-halamine and a quantity of sodium chlorite sufficient to enhance the antimicrobial efficacy of the N-halamine. The present invention is further directed to formulations for disinfecting a contact lens comprising an N-halamine and a quantity of sodium chlorite sufficient to enhance the antimicrobial efficacy of the N-halamine.
