Abstract:
A device for sustained delivery of a poorly water soluble drug is described. A drug reservoir within the device, when in operation, contains an aqueous suspension of the drug mixed with a suspension of an excipient that, in one embodiment, generates acidic groups for a sustained period of time to maintain a desired pH in the aqueous suspension that in turn provides a constant concentration of a soluble form of the drug.
