Tirzepatide and muscle composition changes in people with type 2 diabetes (SURPASS-3 MRI): a post-hoc analysis of a randomised, open-label, parallel-group, phase 3 trial
In the SURPASS-3 MRI substudy, in the context of significant improvements in bodyweight and fat distribution, tirzepatide treatment was associated with potentially favourable changes in muscle fat infiltration and reductions in muscle volume broadly in accordance with the general association between changes in muscle volume and bodyweight. The present findings provide additional information on the potential effect of tirzepatide on muscle health that might help health-care providers when deciding among treatment options for individual patients.
