Ketamine Pharmacology: An Update (Pharmacodynamics and Molecular Aspects, Recent Findings)

G. Mion, Thierry Villevieille
CNS Neuroscience & Therapeutics Summary & key facts 2013 656 citations

Ketamine has been used as a safe anesthetic for more than 50 years and also works well for pain relief. The active form is S(+)-ketamine and it is mainly broken down into an active metabolite called norketamine. Ketamine blocks NMDA receptors in the brain, which helps explain its special effects…

7-Hydroxymitragynine Is an Active Metabolite of Mitragynine and a Key Mediator of Its Analgesic Effects

Andrew C. Kruegel, Rajendra Uprety, Steven G. Grinnell, Cory Langreck, Elizabeth A. Pekarskaya, Valerie Le Rouzic, et al.
ACS Central Science Summary & key facts 2019 200 citations

Researchers found that the main kratom alkaloid, mitragynine, is turned by liver enzymes into a much more active compound called 7-hydroxymitragynine (7‑OH). In lab tests and in mice, 7‑OH acts more strongly at the mu-opioid receptor and reaches brain levels that can explain most or all of the pain relief…

Treatment of Acute Opioid Withdrawal with Ibogaine

Kenneth Alper, Howard S. Lotsof, Geerte M. N. Frenken, D Luciano, Jan Bastiaans
American Journal on Addictions Summary & key facts 1999 195 citations

This report describes 33 open-label treatments with the alkaloid ibogaine given for acute heroin withdrawal in non-medical settings. In 25 of the 33 people, visible signs of opioid withdrawal stopped within 24 hours and stayed absent during 72 hours of observation. The authors note the results are from uncontrolled, non-clinical…

Ibogaine treatment outcomes for opioid dependence from a twelve-month follow-up observational study

Geoff Noller, Chris Frampton, Berra Yazar‐Klosinski

A single ibogaine treatment reduced opioid withdrawal symptoms and achieved opioid cessation or sustained reduced use in dependent individuals as measured over 12 months. Ibogaine's legal availability in New Zealand may offer improved outcomes where legislation supports treatment providers to work closely with other health professionals.

Ibogaine Detoxification Transitions Opioid and Cocaine Abusers Between Dependence and Abstinence: Clinical Observations and Treatment Outcomes

Deborah C. Mash, Linda Duque, Bryan Page, Kathleen Allen-Ferdinand
Frontiers in Pharmacology Summary & key facts 2018 103 citations

Ibogaine is a psychoactive chemical from a West African shrub that some clinics use to help people stop using opioids or stimulants. Small studies, animal research, and many personal reports say a single high dose can cut opioid withdrawal and reduce cravings. For example, one study found 50% of participants…

Safety of ibogaine administration in detoxification of opioid‐dependent individuals: a descriptive open‐label observational study

Thomas Knuijver, Arnt Schellekens, Maarten Belgers, Rogier Donders, Toon van Oosteren, Cornelis Kramers, et al.
Addiction Summary & key facts 2021 45 citations

A descriptive open-label observational study of ibogaine in people with opioid use disorder found the drug can produce clear but reversible heart and nervous-system side effects. Reported effects included QTc prolongation (a change in the heart’s electrical timing), slow heart rate (bradycardia), and severe problems with balance and coordination (ataxia).…

Characteristics of and 3-month health outcomes for people seeking treatment with prescribed cannabis: Real-world evidence from Project Twenty21

Michael T. Lynskey, Anne Katrin Schlag, Alkyoni Athanasiou‐Fragkouli, David R. Badcock, David Nutt
Drug Science Policy and Law Summary & key facts 2023 19 citations

Project Twenty21 collected real-world data from people in the UK who sought prescribed medicinal cannabis. Data at treatment start were available for 2,833 patients and 1,410 had 3-month follow-up for anxiety, chronic pain or PTSD. On average, patients reported improvements in condition-specific symptoms and in general health and quality of…

Oxa-Iboga alkaloids lack cardiac risk and disrupt opioid use in animal models

Václav Havel, Andrew C. Kruegel, Benjamin Bechand, Scot McIntosh, Leia S. Stallings, Alana Hodges, et al.
Nature Communications Summary & key facts 2024 14 citations

Researchers made new versions of the psychedelic drug ibogaine, called oxa-iboga compounds, by changing part of the chemical structure. In lab tests on human heart cells these new compounds did not show the heart-rhythm risk that ibogaine can cause. In tests with male rats, a single dose or a short…

The pharmacokinetics and pharmacodynamics of ibogaine in opioid use disorder patients

Thomas Knuijver, Rob ter Heine, Arnt Schellekens, Paniz Heydari, Luc Lucas, Sjoerd Westra, et al.
Journal of Psychopharmacology Summary & key facts 2024 8 citations

In 14 people with opioid use disorder who each received a single 10 mg/kg dose of ibogaine, researchers measured blood levels of ibogaine and its metabolites over 24 hours and linked those levels to side effects. They found large differences between people in how fast ibogaine was cleared, and that…

Ketamine in Chronic Pain: A Review

Ana Faísco, Rita Lopes Dinis, T N Seixas, Luís Felipe Dias Lopes
Cureus Summary & key facts 2024 7 citations

This review says that low (sub-anesthetic) doses of ketamine can produce strong short-term pain relief by blocking NMDA receptors and by boosting descending pain-inhibiting pathways. It is well documented to help with pain around the time of surgery and is linked to less long-term postoperative pain and lower opioid use.…
