Because the cleavage activity of DPP-4 is depending on the presence of a penultimate Pro or Ala at the N-terminus, analogs of GLP-1 with substitutions at this position should be protected, and analogs with Ser, Val, or alpha-aminobutyric acid remained biologically active (104), so this problem could easily be solved, but the substitutions only increased the half-life from 1.5 to 45 min (104), the reason being a rapid extraction of GLP-1 in the kidneys (105), and probably also other enzymatic attacks (106)

Results 8 studies that reported measurements for 230 patients with depression and 216 controls were included
GLP-1 medications lead to reduced caloric intake, which can affect breast milk supply
They apply at every dose level but become most important during the 4mg to 8mg and 8mg to 12mg transitions
