Disclosed is a paste for injection of a therapeutic agent, the paste comprising an amount of powder comprising an effective amount of the therapeutic agent, wherein the powder is homogeneously contained within a pharmaceutically acceptable carrier, and wherein the paste comprises an injection volume of 0.1 to 3000 microliters.

Pastes for injection of a therapeutic agent

The delivery of biopharmaceutical and other therapeutic agents parenterally to an animal via a minimally invasive, low pain administration is provided. The agents are delivered to the patient via, e.g., the epidermal, dermal, or subcutaneous layer of the skin in a concentrated fours of injectable paste of slurry.

Intracutaneous paste composition

The delivery of biopharmaceutical and other therapeutic agents parenterally to an animal via a minimally invasive, low pain administration is provided. The agents are delivered to the patient via, e.g., the epidermal, dermal, or subcutaneous layer of the skin in a concentrated form of injectable paste of slurry.

Intracutaneous injection

Methods and compositions for systemically or locally administering by implantation a beneficial agent to a subject are described, and include, for example, compositions having burst indices of or less for systemic applications and systems releasing 10% or less of the total dose of beneficial agent in the first 24 hours after implantation for local applications. The compositions include a biocompatible polymer, a biocompatible solvent having low water miscibility that forms a viscous gel with the polymer and limits water uptake by the implant, and a beneficial agent.

Gel composition and methods

Methods and compositions for systemically or locally administering by implantation a beneficial agent to a subject are described, and include, for example, compositions having burst indices of 8 or less for systemic applications and systems releasing 10% or less of the total dose of beneficial agent in the first 24 hours after implantation for local applications. The compositions include a biocompatible polymer, a biocompatible solvent having low water miscibility that forms a viscous gel with the polymer and limits water uptake by the implant, and a beneficial agent.

An injectable depot gel composition containing a polymer, a solvent that can dissolve the polymer and thereby form a viscous gel, a beneficial agent; and an emulsifying agent in the form of a dispersed droplet phase in the viscous gel. The injectable depot gel composition can be prepared by mixing the polymer and the solvent so that the solvent dissolves the polymer and forms a viscous gel. The beneficial agent is dissolved or dispersed in the viscous gel and the emulsifying agent is mixed with the beneficial agent containing viscous gel. The emulsifying agent forms a dispersed droplet phase in the viscous gel to provide the injectable depot gel composition. The injectable depot gel composition can deliver a beneficial agent to a human or animal with a desired release profile.
