Trietazine is primarily used in medical research as an antipsychotic agent. It has been investigated for its ability to modulate dopamine receptors in the central nervous system, making it relevant in the study of psychiatric disorders such as schizophrenia. Its structure allows for interaction with neurotransmitter systems, which can help in understanding receptor binding and neural pathways. Due to its sedative and calming effects, it has also been explored in behavioral studies involving animal models. However, it is not commonly used in clinical practice and remains mostly a compound of interest in experimental pharmacology.
