[Kratom - a short review for pain medicine].

BACKGROUND

Consumption of the psychotropic plant kratom (botanical name: Mitragyna speciosa) is sometimes used for the self-medication of chronic or acute pain. An increase in the use is possible in Germany in the future.

OBJECTIVE

This review provides an overview on kratom for pain specialists. The topics of the review are the pharmacological aspects, the mental effects, the effects on pain and the risks of kratom including possible addiction.

MATERIAL AND

METHODS

We conducted a review of literature in PubMed published until 15 January 2021 resulting in 426 publications of which 8 were specifically concerned with the topic of kratom and pain.

RESULTS

In addition to other alkaloids, kratom also contains 7‑hydroxymitragynine, which is active on opioid receptors. The use of kratom is not without risks, e.g. because there is no standardized form of administration as well as the possibility of direct damage to health and of addiction.

DISCUSSION: There are currently no evidence-based reasons to recommend the use of kratom as an analgesic. It is important for pain specialists to ask patients about a possible abuse of kratom and to be able to inform the patients about the potential risks of kratom.
