Study: Mitragynine does not rely on its metabolism into 7-hydroxymitragynine to produce pain relieving effects

In a new study by the team at University of Florida, scientists found that the metabolite 7-hydroxymitragynine does not account for the pain-relieving effects of its parent alkaloid, mitragynine (Berthold et al., 2021). Here we investigated the hotplate antinociception, pharmacokinetics, and tissue distribution of mitragynine and 7-hydroxymitragynine at equianalgesic oral doses in…mice to determine the …

Interview with Dr. Fabian Pitter Steinmetz on Toxicology and Advocacy by Scientists for Better Drug Policy

Dr. Fabian Pitter Steinmetz is a toxicologist from Germany who in 2021 testified for the World Health Organization’s (WHO) 44th Expert Committee on Drug Dependence (ECDD). There, Dr. Steinmetz gave the case for why kratom should be kept legal. As a member for the European Coalition for Just and Effective Drug Policies (ENCOD), he is …

Interview with Dr. Lance McMahon, Chair of Dept of Pharmacodynamics, UF College of Pharmacy

Dr. Lance McMahon is Chair of the Department of Pharmacodynamics at University of Florida College of Pharmacy. Dr. McMahon is involved in pioneering kratom research that looks at the various kratom alkaloids, how they function on our brain receptors, and how that creates kratom’s complex effects on our bio. We talk about this research, where …

Study: 7-hydroxymitragynine Metabolizes into the More Potent ‘Mitragynine Pseudoindoxyl’ in Human Plasma

A study out of University of Florida published in the journal ACS Pharmacology & Translational Science found that the potency of powder kratom may be due not only to the increased level of 7-hydroxymitragynine (7-HMG), but the way the 7-HMG metabolizes in human plasma (Kamble 2020). Fresh kratom consumed traditionally in Southeast Asia has been …

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 #9: Speciofoline, the Understudied Alkaloid
/

A study on kratom’s chemical composition asks, what does the little-researched kratom alkaloid speciofoline do? And what are the implications for drug interactions and the differences in alkaloid content in kratom products? The brand new study published last week in Scientific Reports examined the chemical composition of 53 kratom products and divided them into two …
