Education about the limitations of surgical diagnosis and the appropriateness of clinical diagnosis requires time and skill that many providers lack (Culley et al., 2017)
Cagrilintide, the second generation (2020s) Novo Nordisk took the Pramlintide concept and applied the same half-life extension strategy that they used with Semaglutide: Kept the proline substitutions (anti-amyloid) Added a C20 fatty diacid via a -Glu linker to a lysine residue, albumin binding Additionally stabilized the N- and C-terminal positions Result: Cagrilintide with a half-life of 6.6 days (vs 50 minutes for Pramlintide)
These effects are still an active area of study, and as with any probiotic, results vary from person to person
