Azacyclonol
Azacyclonol (trade names Ataractan, Calmeran, Frenoton, Frenquel, Psychosan), also known as γ-pipradrol, is a drug which is an ataractive, i.e., an agent which diminishes hallucinations in psychotic individuals. It has also been called a tranquilizer and antipsychotic, though these definitions are not accurate as it does not actually possess such properties.
