About Post Traumatic Stress Disorder

Post-Traumatic Stress Disorder (PTSD) is a psychiatric condition that may occur in people who have experienced or witnessed a traumatic event, series of events or set of circumstances. People with PTSD have intense, disturbing thoughts and feelings related to their experience that persist long after the traumatic event has ended. They may relive the event through flashbacks or nightmares, may feel sadness, fear or anger and may experience a sense of detachment or estrangement from others. As a result of these feelings, people with PTSD may avoid situations or people that remind them of the traumatic event, and they may have strong negative reactions to commonplace stimuli such as loud noises or an accidental touch.

About BNC210

BNC210 is a negative allosteric modulator of the α7 nicotinic acetylcholine receptor under development for the treatment of SAD and PTSD. BNC210 has been given FDA Fast Track designation for treatment of PTSD and other trauma and stressor related disorders and for acute treatment of SAD and other anxiety related disorders.
