Riezene

Riezene is a drug used by the mechanically augmented in Deus Ex: The Fall as a cheaper alternative to Neuropozyne. It helps prevent and reverse Darrow Deficiency Syndrome (DDS), a build-up of glial tissue that blocks electrical signals between augmentation electrodes and human tissue. It is manufactured by Zaaphire Biotech.

Background
Due to strict regulation on Neuropozyne, most biotech and pharmaceutical companies shy away from producing their own anti-rejections drugs, but a critical shortage of Neuropozyne in 2027 lead Zaaphire Biotech to offer Riezene as a cheaper alternative. Zapphire Biotech contacted several LIMB clinics to be included in clinical trials of the new anti-rejection drug. The clinic in Panama City refused, citing patient health concerns from reports of Riezene having adverse effects on users.

Several shipments of Riezene to Panama City were stolen from XNG shipping, the company contracted to send samples of Riezene to clinics for testing, by Belltower employees and sold to Skulls street gang leader, Diego. The gang then sold it on the black market to desperate mechanically augmented people. A back alley doctor, Alvarez Araujo, synthesized the drug in his clinic using its active ingredient: Rievido.

Several mech-augs have died from its use; their deaths being covered up by Belltower troops operating in the area.

Like Neuropozyne, Reizene can be administered intravenously via injection. Although this was done via Dr. Araujo's locally produced version. Advertisements for Zaaphire Biotech's official version shows Riezene in a oral capsule form.
