Breakout data suggests a wake-promoting agent promotes cocaine abstinence
Cocaine dependence is a major public health problem affecting thousands of people around the globe. Despite years of active research there are still no approved medications for the treatment of this life-shattering addiction. Researchers are now hopeful that may soon change based on the results of a controlled study done at the University of Pennsylvania School of Medicine. The study’s findings can be found in the January issue of Journal of Neuropsychopharmacology and on-line at www.neuropsychopharmacology.org. Penn investigators have identified Modafinil – a wake-promoting agent approved for the treatment of narcolepsy – as a possible medicinal treatment for cocaine dependence. In a double-blind, placebo-controlled trial, researchers found Modafinil promoted cocaine abstinence in treatment-seeking outpatients. Modafinil was also shown to blunt cocaine-induced euphoria in a prior study conducted by the same research group, perhaps explaining its clinical advantage. "If confirmed by further investigation, this could be the breakthrough we have been waiting for," says Charles Dackis, MD, Chief of Psychiatry at the University of Pennsylvania Medical Center – Presbyterian, and the study’s principal investigator.
"Cocaine is capable of destroying not only the lives of those addicted, but also those around them," adds Dackis. "An effective treatment for cocaine addiction would help those most vulnerable in our society to overpower their addiction and regain control in their lives." The trial was conducted at Penn’s Treatment Research Center between 2002 and 2003. It involved a sample of 62 cocaine-dependent patients (aged 25-63) free of significant medical and psychiatric conditions. All participants were from the Philadelphia area. After initial screenings, eligible patients were randomized to a single morning dose of Modafinil (400 mg), or matching placebo tablets, that was continued for eight weeks along with twice-weekly cognitive behavioral therapy (CBT). Thirty participants were treated with Modafinil; and 32 were given placebo.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
