Opioid Agonist Therapy (OAT) is a treatment approach for individuals with opioid use disorder. It involves the use of medications, such as methadone or buprenorphine, which activate the same brain receptors as opioids. This helps to reduce cravings and withdrawal symptoms, allowing individuals to stabilize their lives and engage in recovery. OAT is often combined with counseling and support services to address the psychological aspects of addiction. By providing a safer alternative to illicit opioid use, OAT aims to improve overall health and reduce the risks associated with opioid misuse, such as overdose and infectious diseases.
