5-Aminoisotonitazene (5-IT) is a synthetic opioid analgesic that belongs to the benzomorphan class of opioids. It is a highly potent and addictive drug that has similar effects to morphine but has a higher potential for abuse and addiction. 5-IT was developed in the 1970s as a research compound and has since gained attention due to its potential use as a pharmaceutical agent.

Chemistry and Structure

5-Aminoisotonitazene has a chemical structure that belongs to the morphine-type opioid receptor agonists. It is composed of an indole ring, a morpholine ring, and a benzene ring. The indole ring is substituted with an amine group at the 5-position, while the morpholine ring is substituted with an isotonitazene moiety. The benzene ring is connected to the indole ring via a single carbon atom.


5-Aminoisotonitazene binds to opioid receptors in the brain and spinal cord, specifically the μ-opioid receptors. It produces analgesic effects by activating the opioidergic system and inhibiting the perception of pain. However, it also exhibits other pharmacological properties, including sedative, respiratory depression, and euphoric effects.

Abuse and Addiction

5-Aminoisotonitazene has high potential for abuse and addiction due to its potent analgesic effect and ability to produce euphoria. Users often experience tolerance and physical dependence, which can lead to compulsive use and addiction. The withdrawal symptoms associated with 5-IT use can be severe and may include anxiety, restlessness, sweating, and diarrhea.

Legal Status

5-Aminoisotonitazene is not listed in the schedules of controlled substances in many countries. However, it has been classified as a Schedule I controlled substance in the United States by the Drug Enforcement Administration (DEA). Scheduling a substance under the Controlled Substances Act is a determination of its potential for abuse and risk of addiction.

Safety and Toxicity

5-Aminoisotonitazene has a narrow therapeutic index, meaning there is a relatively small difference between the amount required for therapeutic effects and the amount that can lead to serious side effects. Common adverse effects associated with 5-IT use include respiratory depression, coma, hypotension, and respiratory arrest. Prolonged use of 5-IT can also lead to organ damage, such as kidney and liver damage.


5-Aminoisotonitazene is a synthetic opioid analgesic that exhibits potent analgesic properties and a high potential for abuse. Its chemical structure and pharmacological profile make it similar to morphine, but it exhibits a higher potential for addiction. 5-IT is not a pharmaceutical agent that is approved for clinical use, and its abuse has led to its classification as a Schedule I controlled substance in certain countries. It is essential to raise awareness about the potential risks associated with 5-IT to prevent its misuse and addiction.
