Phencyclidine/Schizophrenia: One View Toward the Past, The Other to the Future

Abstract

The history of the chemical synthesis and animal/human pharmacology of phencyclidine is documented. From its early use as a general anesthetic, chemical model of schizophrenia, and drug of abuse, phencyclidine has had a checkered history. Research with this agent and its chemical derivatives like ketamine have provided a solid foundation for just a beginning to understanding the neuropathology of schizophrenia.
