Cyclopregnol (neurosterone) is a synthetic pregnane steroid, developed in the 1950s by the British Drug Houses, Ltd, for the treatment of psychiatric disorders, such as anxiety, depression and obsessive behavior. In a clinical study, cyclopregnol was not superior to placebo and was inferior to chlorpromazine.
