Joo JH, Sharma N, Shaia J, et al

Berk E, Christ T, Schwarz S, Ravens U, Knaut M, Kaumann AJ (2016) In permanent atrial fibrillation, PDE3 reduces force responses to 5-HT, but PDE3 and PDE4 do not cause the blunting of atrial arrhythmias

Clinical trials show semaglutide produces approximately 15% average body weight loss, while Saxenda (liraglutide) produces 5-8% on average

At 48 weeks, the 12 mg arm produced average losses of about 24% of baseline weight, 8 mg gave reductions of ~1718%, and 4 mg delivered double-digit but more moderate decreases
