While extended-release antipsychotics have been a commercial success, they still have a limited therapeutic duration and poor pharmacokinetics, resulting in poor compliance. Delpor Inc. is aiming to improve all three of these characteristics with its implantable Prozor drug delivery device.

Prozor is a tubular device 40 mm long and 4 mm in diameter that is subcutaneously implanted in the arm to provide continuous drug delivery via passive diffusion.
