  • Patent number: 10758626
    Abstract: The present invention relates in general to polymer-bioactive agent conjugates for delivering a bioactive agent to a subject. The polymer-bioactive agent conjugates contain triazole moieties in the polymer backbone and a bioactive moiety selected from quinolones, NSAIDs and mixtures thereof. The present invention also relates to methods for preparing the polymer conjugates using click cycloaddition chemical reactions, to monomer-bioactive agent conjugates suitable for preparing the polymer conjugates, and to pharmaceutical products comprising the polymer conjugates for the post-surgical care to treat or prevent infections, provide analgesia and treat inflammation.

  • Publication number: 20200024403
    Abstract: The present disclosure relates to injectable compositions and methods of making injectable compositions of moisture curing siloxane polymers for forming accommodating intraocular lenses. In certain embodiments, the moisture curing siloxane polymers are comprised of an organosilicon compound and a hydrolytically sensitive siloxane moiety and have a specific gravity of greater than about 0.95, a number average molecular weight (Mn) greater than about 5,000 or about 20,000 and a weight average molecular weight (Mw) greater than about 20,000 or about 40,000. The disclosure includes accommodating intraocular lenses formed from moisture curing siloxane polymers and having a modulus of elasticity of less than about 6 kPa, less than 20% post-cure extractables, refractive index ranging from 1.4 to 1.5 and dioptric range of accommodation of 0D to 10D.
