FIELD OF THE INVENTION 0008. A prolonged QT interval is a marker of potential Ventricular tachyarrhythmia which, and can result in death. 0002 This invention is directed to a method of treating Serious complications, including Ventricular tachyarrhyth addiction to an illicit or otherwise addictive substance, mia and death, can result from prolongation of the treated including acute and post-acute withdrawal symptoms, com patient’s QT interval by ibogaine, rendering high doses of prising treating an addicted patient with ibogaine, ibogaine ibogaine unacceptable. Heretofore, it was unclear whether a derivative, orpharmaceutically acceptable salt and/or Solvate therapeutic dose of ibogaine could be found that resulted in thereof at a therapeutic dosage that provides both an average QT interval prolongation within an acceptable range. It is serum concentration of about 50 ng/mL to about 850 ng/mL expected that other compounds that share ibogaine's core and a maximum QT interval prolongation of no more than structure will have a similar prolongation effect on QT inter about 50 milliseconds. val. See, U.S. Provisional Patent Application No. 61/945,746 filed Feb. 27, 2014 entitled METHOD FOR ACUTE AND STATE OF THE ART LONG-TERM TREATMENT OF DRUG ADDICTION, which application is incorporated by reference in its entirety. 0003 Substance addiction is a serious public health prob 0009.
