semaglutide compound vs tirzepatide compound Semaglutide: Key Differences Explained Addressing the Weight Loss Injectable

Lys 16 Replacing the Gly 22 of GLP-1 with Ala or Aib slightly decreased both its affinity and activity (Ala IC 50 : 0.27 nM0.57 nM;EC 50 : 2.6 nM4 nM)

Semaglutide mimics GLP-1 (glucose-like-peptide-1), whereas tirzepatide imitates both GLP-1 and another hormoneGIP (glucose-dependent insulinotropic polypeptide)

This translated into a significantly higher likelihood of achieving the conventional glycemic target of HbA1c 30, those randomized to tirzepatide experienced 36 adjudicated cardiovascular deaths or heart failure worsening events versus 56 in the placebo group, representing a 38% reduction primarily driven by fewer heart failure exacerbations

Short-acting GLP-1 medications (exenatide immediate-release, lixisenatide) must be administered within 60 minutes before meals for optimal post-prandial glucose control
