Prazosin drug shows promise against PTSD-related nightmares

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 randomized controlled trials.

"The studies showed the drug was well-tolerated and can take effect rapidly, within days to weeks, and some patients reported a return of nightmares when the course of prazosin was stopped," says Simon Kung, M.D., a Mayo Clinic psychiatrist and principal investigator of the study.

"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.

One possible cause of nightmare symptoms, such as disrupted sleep, is the development of overstimulated chemical messenger norepinephrine receptors in the central nervous system.

"The thinking is that pharmacologic agents, like prazosin, that block these receptors may be ideal in treating nightmares," Dr. Kung says.

    I wasn't in a typical war but prison and institutions for a total of 38 years. From age 11 to 52 I was only on the streets for 3 years total. Been diaignosed as many things including disasociateive reaction, depressed, bad anxiety etc. My last prison was for 29 years for homicide. A councilor I have been seeing suggested to my doctor after learning of my constant nightmares and violent memories and sleep deprovation, that I try Prozasin 1 mg.Teo days later I had no nightmares and slept a full night, which I don't ever know as happening! 30 days later all my depression and anxiety are gone!! I have been out of prison for almost 11 years and thuis last 30 days I have felt more calm and relaxed that I can remember ever! I have been afraid that one day I was going to experience some terriable side effect or something but nothing yet and God willing nothing will. If I could I would like to shale the hands of the people that designed this drug! Thank you and God Bless who ever is responciable!! Resoectfully, Richard
