  • Publication number: 20080044476
    Abstract: Viscous formulations and methods of using such compositions, useful for intramuscular and intra-articular injection are provided to treat peripheral conditions. Such compositions can include triamcinolone particles present in a therapeutically effective amount, a viscosity inducing component, and an aqueous carrier component. The compositions have viscosities of at least about 10 cps or about 100 cps at a shear rate of 0.1/second. In a preferred embodiment, the viscosity is in the range of from about 80,000 cps to about 300,000 cps. In a most preferred embodiment, the viscosity is in the range of from about 140,000 cps to about 280,000 cps at a shear rate of 0.1/second at 25° C. The compositions advantageously suspend the triamcinolone particles for prolonged periods of time.

  • Publication number: 20070224278
    Abstract: Triamcinolone compositions, and methods of using such compositions, useful for injection into the vitreous of human eyes or into a joint are provided. Such compositions can include triamcinolone particles present in a therapeutically effective amount, a viscosity inducing component, and an aqueous carrier component. The compositions have viscosities of at least about 10 cps or about 100 cps at a shear rate of 0.1/second. In a preferred embodiment, the viscosity is in the range of from about 80,000 cps to about 300,000 cps. In a most preferred embodiment, the viscosity is in the range of from about 140,000 cps to about 280,000 cps t a shear rate of 0.1/second at 25° C. The compositions advantageously suspend the triamcinolone particles for prolonged periods of time.

  • Publication number: 20050101582
    Abstract: Compositions, and methods of using such compositions, useful for injection into the posterior segments of human or animal eyes are provided. Such compositions include corticosteroid component-containing particles present in a therapeutically effective amount, a viscosity inducing component, and an aqueous carrier component. The compositions have viscosities of at least about 10 cps or about 100 cps at a shear rate of 0.1/second. In a preferred embodiment, the viscosity is in the range of from about 140,000 cps to about 300,000 cps. The compositions advantageously suspend the particles for prolonged periods of time.
