Ro 64-6198 is a selective GABA_B receptor agonist used in biochemical research, particularly in the central nervous system. It plays a role in understanding the mechanisms of the GABA system in the brain.

In research, Ro 64-6198 has shown potential in reducing behaviors associated with stress and anxiety without causing common side effects seen in sleeping pills or benzodiazepines, such as addiction or withdrawal symptoms.

Additionally, studies evaluate its role in controlling appetite and addictive behaviors, particularly substance abuse like alcohol and stimulants, as it can inhibit the release of neurotransmitters involved in addiction.

Overall, Ro 64-6198 is an important tool in researching psychiatric disorders such as anxiety disorders, depression, and addiction. Although not used clinically, data from studies help pave the way for developing more effective and safer new drugs.
