Trulicity Deep Dive

Trulicity (dulaglutide) is a once-weekly GLP-1 agonist approved for type 2 diabetes. It is well-tolerated and has cardiovascular outcome data (REWIND trial), but produces less weight loss than semaglutide.

Ozempic Deep Dive

Ozempic (semaglutide) consistently outperforms dulaglutide in head-to-head trials for both HbA1c reduction and weight loss. The SUSTAIN 7 trial directly comparing them showed semaglutide's superiority at both 0.5mg and 1mg doses.
