Neuropozyne

Neuropozyne, informally called Nu-poz, is an anti-rejection drug used by mechanically-augmented humans in Deus Ex: Human Revolution and Deus Ex: Icarus Effect to stop the build up of glial tissue around augmentations.

Background
As augmentations are placed over raw human tissue, such as the stub of a limb or an empty eye socket, the body will attempt to stop the bleeding around the open area, creating scar tissue that solidifies in augmentations, damaging them. Neuropozyne is some form of local anticoagulant that keeps the augmentations free of scar tissue. It is required at least weekly for the average human, and although it is not produced with especially rare materials, its distribution is heavily monitored and it can sell for extraordinary prices on the secondhand market.

In Deus Ex: Human Revolution, at the Sarif Industries headquarters in Detroit, Adam Jensen is involved in a quest entailing Neuropozyne thefts.
