ABSTRACT:
The invention features an implantable device for the automatic delivery of an active ingredient according to an adjustable delivery profile. The device includes a housing; a reservoir operatively connected to the housing and arranged to store a solid composition including the active ingredient; an actuator arranged within the housing to move the solid composition from the reservoir to a transit area, wherein the solid composition exits the housing at the transit area; a controller that acts on the actuator to adjust movement of the solid composition out of the housing according to the adjustable delivery profile; and a power source arranged to provide energy to the actuator and the controller. The solid composition can be an elongate, solid composition comprising a drug, and up to 90% of a carrier, wherein the composition has a cross-section of less than 0.5 mm, and wherein the drug and the carrier are selected and compounded in a proportion such that the drug is immediately released from the carrier upon contact with a liquid.
