Clinical pearls
- Once-weekly dosing improves adherence vs daily GLP-1 RAs
- REWIND: reduced MACE in T2DM with more heterogeneous CV risk population vs LEADER/SUSTAIN-6
- No significant renal dose adjustment — can use across eGFR range (supported by REWIND sub-analysis)
- Ready-to-use auto-injector — most convenient GLP-1 RA for patients with dexterity issues
Contraindications
- Personal or family history of medullary thyroid cancer
- MEN-2 syndrome
