Subutex is a medication that is primarily used for the treatment of opioid dependence. Its generic name is buprenorphine, and it belongs to a class of drugs known as partial opioid agonists.

Subutex works by binding to the same receptors in the brain as opioids, such as heroin or prescription painkillers. However, unlike full opioid agonists, Subutex only partially activates these receptors, leading to reduced cravings and withdrawal symptoms. By doing so, it helps individuals reduce or stop their use of opioids.
