  • Patent number: 8118790
    Abstract: The present invention is an ophthalmic injection system with a limited reuse assembly and a tip segment. The tip segment is connectable to and removable from the limited reuse assembly. The tip segment includes a dispensing chamber, a plunger, and a housing. The dispensing chamber holds a quantity of a substance to be injected into an eye. The proximate end of the plunger has a first mechanical linkage interface. The limited reuse assembly of the ophthalmic injection system has a power source, a controller, a motor, a second mechanical linkage interface located on an end of the motor shaft; and a second housing. The first mechanical linkage interface is mateable with the second mechanical linkage interface such that when the tip segment is connected to the limited reuse assembly, the first mechanical linkage interface mates with the second mechanical linkage interface so that motion of the shaft results in motion of the plunger.

  • Patent number: 8101582
    Abstract: Ophthalmic pharmaceutical compositions containing tobramycin, dexamethasone and deacetylated xanthan gum are described. The compositions provide longer ocular retention for enhanced ocular bioavailability of tobramycin and dexamethasone. In a preferred embodiment, the compositions also provide for improved suspension of dexamethasone. The concentration of ionizable species in the compositions is controlled so as to prevent precipitation of the xanthan gum as a result of ionic interactions between tobramycin and xanthan gum, while allowing for a restoration of viscosity upon topical application of the compositions to the eye. The use of deacetylated xanthan gum is disclosed, so as to avoid formulation instability caused by pH drift during storage.
