A device for transdermal drug delivery and administration of differing dosages at specific times of the day automatically pursuant to a pre-programmed dosage profile, includes a control and display unit, a two-part dispensing mechanism, a drug reservoir, an administration element, and a solvent removal element. The dispensing mechanism may be a peristaltic pump having an active portion with a motor, a roller, a mounting plate and a detachable passive portion with tubing and a housing. The motor and roller are mounted in the reusable portion of the delivery device with the control unit and a power source. The speed of the micromotor is controlled by the control unit, so that the turning speed of the roller is controlled which, in turn, controls the flow rate to the administration. The passive portion and drug reservoir are detachable along with the administration element for attaching a new dosing reservoir. |
