ABSTRACT:
The invention provides a dispensing device comprising a loading dose (first agent delivery means) for short-term and continuous delivery of an agent having a high potency, retained together with a long-term dispensing device (second agent delivery means) capable of a 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 may be delivered to the environment of use over time. A rapid initial delivery of beneficial agent is followed by continuous and prolonged delivery of agent.
