  • Patent number: 9144561
    Abstract: The present invention is directed to the provision of pharmaceutical compositions. The compositions include a therapeutic agent and a relatively low amount of surfactant for providing higher bioavailability of the therapeutic agent. The compositions are particularly desirable as ophthalmic compositions in which the therapeutic agent is a prostaglandin such as travoprost and the surfactant is a vegetable oil such as castor oil.

  • Patent number: 8450287
    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.

  • Patent number: 8323630
    Abstract: The present invention is directed to the provision of multi-dose, self-preserved ophthalmic compositions. The compositions possess sufficient antimicrobial activity to satisfy USP preservative efficacy requirements, as well as similar preservative standards (e.g., EP and JP), without requiring the presence of conventional anti-microbial preservative agents, such as benzalkonium chloride. The compositions are effectively preserved by a balanced ionic buffer system containing zinc ions at a concentration of 0.04 to 0.9 mM, preferably 0.04 to 0.4 mM. One aspect of the balanced buffer system is limitation of the amount of buffering anions present to a concentration of 15 mM or less, preferably 5 mM or less. In a preferred embodiment, the compositions also contain borate or, most preferably, one or more borate/polyol complexes. The use of propylene glycol as the polyol in such complexes is strongly preferred.
