Many Veterans with posttraumatic stress disorder (PTSD) have trouble sleeping or have
frequent nightmares. So far, no medication has been approved for treatment of insomnia in
PTSD. The purpose of this research study is to find out if taking medications called
trazodone, eszopiclone, or gabapentin can help decrease symptoms of insomnia in patients with
PTSD. PTSD is a form of intense anxiety which sometimes results from severe trauma. Symptoms
may include nightmares, flashbacks, troublesome memories, difficulty sleeping, poor
concentration, irritability, anger, and emotional withdrawal. Insomnia is a disorder that can
make it hard to fall sleep, stay asleep or cause a person to wake up too early and not be
able to fall back to sleep.
