Journal Club #25: Dopamine Response to Mitragynine in Rats
/

Dr. Jon Cachat and host Brian Gallagher look at a study that examined dopamine levels with an electrochemical sensor in rats administered with various levels of mitragynine. Dopamine release was detected as significant levels after a high dose of mitragynine after 4 days. Questions explored in this episode include: Does this accurately measure the kratom …

Another study from University of Florida is the “first report that has simultaneously evaluated the systemic exposure of 11 kratom alkaloids following the administration of traditional and commercial kratom products” (Kamble, 2021). Researchers looked at the pharmacokinectics (how drugs move through the body and are metabolized) of alkaloids in rat plasma following the oral administration …

Levels of Kratom Alkaloid Mitragynine Were Likely Overestimated in Autopsies

A research article in the journal Drug Testing and Analysis uncovered a flaw in previous examinations of kratom’s main alkaloid, mitragynine. The study, lead by University of Florida pharmacutics researcher Dr. Abisheak Sharma, stated: There is a possibility that earlier reported studies did not separate the four mitragynine diastereomers, resulting in over‐quantification of mitragynine in …

Journal Club #13: How Kratom Alkaloids Act on Brain Receptors
/

We all know the mitragynine and 7-hydroxymitraginine act on the mu-opioid receptor. But for episode #13 of Journal Club we talk about a study that looks closely at the binding affinity of various kratom alkaloids on the plethora of opioid and adrenergic receptors in the brain. How exactly does this work? How do different alkaloids …

UF Researchers First to Grow Kratom for Published Study

In one of the first formal studies of its kind, if not the very first, a team from University of Florida cultivated 68 kratom trees and fertilized them at different rates, then measured for alkaloid content, chlorophyll, and total biomass. The study, “Effects of Nutrient Fertility on Growth and Alkaloidal Content in Mitragyna speciosa (Kratom)” …
