Abstract
The present invention relates to devices for providing an effective change in a drug delivery rate. In an exemplary embodiment the invention provides a drug delivery device using a method for changing a delivery rate for a drug from a first delivery rate to a second higher delivery rate, comprising the steps of: (a) Deliver the drug at the first delivery rate, (b) deliver the drug at a third delivery rate for a first period of time, the third delivery rate being higher than the second delivery rate, and (c) after the first period of time deliver the drug at the second delivery rate. By using a higher “bolus-like” third delivery rate for a first period of time it is possible relatively fast to fill up a depot corresponding to the new second delivery rate.
