  • Publication number: 20140107071
    Abstract: Provided according to some embodiments of the invention are methods of manufacturing a pharmaceutical composition. In some embodiments, such methods include homogenizing at a first excipient composition that includes a viscosity agent and at least one solvent to form a first premix composition; separately homogenizing at least one active pharmaceutical ingredient (API) and a second excipient composition to form a second premix composition; and combining the first premix composition and the second premix composition to form the composition. The pre-mixing of constituents may increase the stability of the API and provide uniformity of the dispersion of the constituents throughout the final topical composition.

  • Patent number: 8399005
    Abstract: The present invention is directed to compositions comprising at least one nitric oxide donor and at least one second therapeutically active agent with antimicrobial or wound healing capability. In one embodiment, the nitric oxide donor is a nanoparticle which is designed to control for the amount and duration of release of nitric oxide. The nanoparticle may further comprise the additional therapeutically active agent. The composition is useful for enhancing wound healing and for treating and preventing microbial infection. In one embodiment, the composition is directed toward reducing oral bacteria or dental plaque. The combination of one or more nitric oxide donors and one or more additional therapeutically active agent results in unexpected synergistic effects, wherein both the antimicrobial efficacy of the nitric oxide and the antimicrobial or wound healing efficacy of the second therapeutically active agent are enhanced.
