Which substance is considered similar to PCP?

Ketamine is considered similar to PCP (phencyclidine) because both substances belong to the class of dissociative anesthetics. They have similar effects on the mind and body, primarily through their action as NMDA receptor antagonists. Both can induce dissociative states, which lead to alterations in perception, cognition, and motor function. Ketamine is often used in medical settings for anesthesia and treatment of depression, while PCP was initially developed as an anesthetic but is more commonly known for its recreational use and associated psychotomimetic effects. This overlapping pharmacological profile is what makes ketamine and PCP similar substances in terms of their dissociative and anesthetic properties.
