LAS VEGAS, July 10, 2007 (PRIME NEWSWIRE) -- Samaritan Pharmaceuticals Inc. (AMEX:LIV - News), a developer of innovative drugs, is pleased to announce it has confirmed Caprospinol's (SP-233) efficacy in its ability to dramatically decrease beta amyloid plaque in the brain, accompanied by a complete recovery of memory back to baseline (p=0.002), as shown in a Morris water maze task. This study confirms previously reported in-vitro data and suggests Caprospinol may not only slow down Alzheimer's but may also reverse plaque-related brain injuries associated with the mind-robbing disease of Alzheimer's.
