Study findings on clinical trial research are outlined in reports from Peking University



2009 AUG 3 - (NewsRx.com) -- "Tetrodotoxin (TTX) is a neurotoxin found in Puffer fish and other marine animals. New clinical studies Suggest that low-dose TTX can safely relieve severe, treatment-resistant cancer pain," researchers in Beijing, People's Republic of China report.

"The therapeutic potential of TTX in addiction is supported by studies in laboratory animals. The purpose of this double-blind, placebo-controlled study was to assess the effect of a single intramuscular dose of TTX on cue-induced craving and anxiety in abstinent heroin addicts. Forty-five abstinent heroin addicts were randomly assigned to three treatment groups: placebo, 5 mu g TTX, or 10 mu g TTX. were exposed to a neutral video or a heroin-related video. Craving. anxiety, blood pressure, and heart rate were measured pre- and post-exposure. Heroin-related cues increased both craving and anxiety and had no effect on blood pressure and heart rate. A single dose of TTX dose-dependently attenuated the increases in craving and anxiety while having no effect on blood pressure or heart rate," wrote J. Shi and colleagues, Peking University.

The researchers concluded: "The results suggest that low-dose TTX is acutely effective in reducing cue-induced increases in heroin craving and associated anxiety."

Shi and colleagues published their study in Pharmacology Biochemistry and Behavior (Tetrodotoxin reduces cue-induced drug craving and anxiety in abstinent heroin addicts. Pharmacology Biochemistry and Behavior, 2009;92(4):603-607).
