Findings
posttraumatic stress disorder
In this randomized clinical trial of short-term mifepristone treatment (600 mg per day for 7 days) in 80 male veterans with posttraumatic stress disorder (41 receiving mifepristone and 39 receiving placebo), the difference in the clinical response rate to mifepristone vs placebo at 4 and 12 weeks was less than the predefined clinical margin used to define efficacy.
