Nalfurafine (INN, USAN)[3] (brand name Remitch; former developmental code names TRK-820, AC-820, MT-9938) is an antipruritic (anti-itch drug) that is marketed in Japan for the treatment of uremic pruritus in individuals with chronic kidney disease undergoing hemodialysis.[2][4] It activates the
History
[edit]Nalfurafine was derived from structural modification of the opioid antagonist naltrexone.[9][10] It was first synthesized and characterized in 1998,[2] and was approved for clinical use in Japan as an intravenous drug under the brand name Remitch in 2009.[4] The developer of nalfurafine also sought approval in Europe under the brand name Winfuran, but the Marketing Authorization Application was declined by the European Medicines Agency.[11] The drug was originally developed as an analgesic in surgery, but while effective in animal models of nociception,[12] it was repurposed as an antipruritic at lower treatment doses due to an apparently unacceptable incidence of sedative effects in humans.[4][7] As of 2015, nalfurafine is also in clinical trials for the treatment of cholestatic pruritus in Japan for patients with chronic liver disease, and for the treatment of uremic pruritus in the United States.[4][13]
Effects
[edit]Unlike other KOR agonists, nalfurafine does not produce hallucinogenic effects in humans.[6][7] Single intramuscular injections of up to 30
Mechanism of action
[edit]Nalfurafine is an orally active, centrally acting, highly potent, selective full agonist of the
Nalfurafine has been found in vitro to bind to the
Research
[edit]Nalfurafine has been found to be effective in a variety of animal models relevant to drug abuse, addiction, and dependence, and may represent a novel potential treatment for these maladies.[6] In rodents, the drug attenuates the discriminative and rewarding effects of cocaine and the rewarding and locomotor effects of morphine, and diminishes the mecamylamine-precipitated aversive effect of nicotine withdrawal.[6]
