Drug addiction is a chronic brain disease that is a serious social problem and causes enormous financial burden. Because mitochondrial abnormalities have been associated with opiate addiction, we examined the effect of morphine on mtDNA levels in rat and mouse models of addiction and in cultured cells. We found that mtDNA copy number was significantly reduced in the hippocampus and peripheral b...

IN THIS ISSUE OF JAMA, PATRICK ET AL 1 DESCRIBE THE EFfects on newborn infants of the widespread availability of prescription opiate medications. These medications provide superior pain control for cancer and chronic pain, but have been overprescribed, diverted, and sold illegally, creating a new opiate addiction pathway and a public health burden for maternal and child health. Overdose mortali...

BACKGROUND/AIM Relapse of opiate dependence is a common occurrence after detoxification and introduction of opiate addicts in abstinence from opiates. Clinical evaluation showed that over 90% of opiate addicts exhibit depressive manifestations during detoxification, or develop post-detoxification depression. The aim of this study was to determine differences in the frequency of relapses, severi...

background; methadone maintenance therapy (mmt) is an evidence-based approach for opiate addiction treatment. while its effectiveness in reducing opiate use has been evidently verified, unanswered questions with respect to the cultural scenarios for mmt programs remain unanswered. this study was conducted to explore understanding address mmt initiation among a women-recruited sample of persons ...

background: the common detoxification method is replacement of long effect opiate by short effect opiate and then reducing its amount gradually. more modern method is ultra rapid opiate detoxification (urod) by opiate antagonists, which is performed by general anesthesia. the advantages of two methods have not been confirmed. this study aimed to compare effectiveness and withdrawal rate in both...

Withdrawal from opiates, such as heroin or oral narcotics, is characterized by a host of aversive physical and emotional symptoms. High rates of relapse and limited treatment success rates for opiate addiction have prompted a search for new approaches. For many opiate addicts, achieving abstinence may be further complicated by poly-drug use and co-morbid mental disorders. Research over the past...

Introduction: The persistence of post-detoxification problems in drug addiction is one of the disadvantages of the ultra-rapid opioid detoxification (UROD) method. Transcranial direct current stimulation (tDCS) has been introduced in experimental addiction treatment for some years. Results of pilot studies suggest that it might be a promising method for addiction treatment. This study explores ...

Opiate withdrawal/negative reinforcement has been implicated as one of the mechanisms for the progression from impulsive to compulsive drug use. Increase in the intracellular cAMP level and protein kinase A (PKA) activities within the neurocircuitry of addiction has been a leading hypothesis for opiate addiction. This increase requires the phosphorylation of μ-opioid receptor (MOR) at Tyr336 by...
