A Case of 7-Hydroxymitragynine Use Disorder Treated With Buprenorphine
Journal of Addiction Medicine
|March 24, 2026
Summary
7-hydroxymitragynine (7-HMG) is a potent opioid found in kratom. Treatment for 7-HMG use disorder may benefit from medication for opioid use disorder, like methadone and buprenorphine.
Area of Science:
- Pharmacology
- Addiction Medicine
- Toxicology
Background:
- Kratom contains mitragynine and the more potent 7-hydroxymitragynine (7-HMG).
- Concentrated 7-HMG products are increasingly marketed, posing risks due to higher potency.
- Limited research exists on managing 7-HMG withdrawal and addiction.
Purpose of the Study:
- To describe the clinical management of a patient with 7-HMG use disorder.
- To highlight the potential benefits of medication for opioid use disorder (MOUD) in treating 7-HMG addiction.
Main Methods:
- A case study of a male patient in his 30s hospitalized for 7-HMG use disorder treatment.
- Management included stabilization with methadone (50 mg) over 36 hours.
- Tapering of methadone followed by buprenorphine induction (16 mg/day) for craving and depression.
Main Results:
- Opioid withdrawal symptoms emerged within 8 hours and were managed with methadone.
- Buprenorphine treatment led to resolved craving and improved depression.
- The patient showed positive response to MOUD for 7-HMG use disorder.
Conclusions:
- 7-HMG is an underrecognized, potent opioid with increasing public health implications.
- Medication for opioid use disorder (MOUD) shows promise for managing 7-HMG use disorder.
- Further research is crucial to understand 7-HMG's effects and refine treatment strategies.

Opioid Analgesics: Synthetic and Semisynthetic Opioids
1.4K
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Opioid Analgesics: Morphine and Other Natural Cogeners
1.4K
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Drug Abuse and Addiction: Pharmacological Phenomena
1.5K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Opioid Receptors: Overview
6.3K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Analgesia and Pain Management
2.9K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
