Is There a Pharmacokinetic Interaction Between St John's Wort and Metformin?
Abstract
The goal of the study is to examine the difference of the pharmacokinetics of metformin with and without a 3 weeks pretreatment of St John's Wort. Furthermore secondary objectives include changes in GLP-1, C-peptide, serum-insulin and plasma-glucose during an oral glucose tolerance test, changes in OCT1 mRNA in plasma and changes in leptin and lipid-profile following this possible interaction.
Conditions: Type 2 Diabetes, Depression.
Primary outcome: Change in Area Under Curve (AUC) 0-24h of metformin.
Enrollment: 20 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 20 participants or records.
