Effects of tirzepatide on liver metabolic profiling and pathways Using UHPLC-MS/MS in both the ESI (+) and ESI (-) modes to ensure comprehensive metabolite coverage, we identified 2,268 metabolites that were subsequently categorised into 17 superclasses across all samples (Supplementary Fig
Between January 2024 and June 2025, first-time prescribing increased at an average rate of 0.01 percentage points per month, a 239% gain over the period
