    摘要: The invention provides a long-term dispensing device comprising a first agent delivery means for short-term and continuous delivery of agent, retained together with a second agent delivery means capable of long-term and continuous delivery of agent. The combination of first and second agent delivery means provides a device in which a substantially constant dose of beneficial agent is delivered to the environment of use over time. A rapid delivery of beneficial agent is followed by continuous and prolonged delivery of agent. In a preferred embodiment the device includes (1) a short term delivery means for rapid and continuous delivery of agent to the environment of use; and (2) a long-term delivery means comprising a semipermeable wall which surrounds and defines an internal lumen; a means in the lumen for expanding and occupying an increased volume of the lumen; a beneficial agent in the lumen that provides a dispensable formulation to the environment of use; and a means in the device for delivery of the beneficial agent to the environment of use over time.

    摘要: The invention provides a dispensing device (10) comprising a loading dose (32) (first agent delivery device) for short-term and continuous delivery of agent, retained together with a long-term dispensing device (12) (second agent delivery device) capable of long-term and continuous delivery of agent. The combination of first and second agent delivery device provides a device in which a substantially constant dose of beneficial agent is delivered to the environment of use over time. A rapid delivery of beneficial agent is followed by continuous and prolonged delivery of agent. In a preferred embodiment the device includes (A) a loading dose chamber (30) and retaining device (16) retaining a loading dose (32) (short-term delivery device) for rapid and continuous delivery of agent to the environment of use; and (B) a long-term dispensing device (12) (long-term delivery device) comprising a semipermeable wall (14) which surrounds and defines an internal lumen (20), a driving source (22) (expansion device) in the lumen for expanding and occupying an increased volume of the lumen, a beneficial agent (24) in the lumen that provides a dispensable formulation to the environment of use, and an exit (28) in the device for delivery of the beneficial agent to the environment of use over time. A densifier (26) and/or a moveable barrier device (34) may also be included in the lumen of the long-term dispensing device.
