Patent 9089478 was granted and assigned to Allergen on July, 2015 by the United States Patent and Trademark Office.
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.
