Review: Blood pressure drug effective for treating PTSD-related nightmares

March 6, 2012

Mayo Clinic researchers this week will announce the use of the blood pressure drug prazosin as an effective treatment to curb post- traumatic stress disorder (PTSD)-related nightmares.

In a presentation during the 20th European Congress of Psychiatry in Prague, Mayo Clinic psychiatrists will present a systematic literature review of prazosin in the treatment of nightmares. Researchers investigated 12 prazosin studies, four of which were .

"There's not much available for treating nightmares in terms of medications, so prazosin is a promising option," Dr. Kung says.

He added that the literature review opens the possibility of widening the use of prazosin. "Because of the low side effects of prazosin as reported in these studies, it seems logical to extend the use of prazosin to non-PTSD nightmares."

For people who suffer from PTSD, one of the most distressing effects is the experience of nightmares; in particular, the kinds of dreams that ruin sleep with extremely frightening images of physical or emotional threats. Nightmares can be so severe that they can contribute to alcoholism, substance abuse and suicidal thinking.
