That Persistent Challenges of Conventional Insulin Therapy

Despite decades of reprefement, standard insulin regimens remain imperfect. Intermediate- acting insulins like NPH often produce a pronounced peak sereal hours after injection, insuining the risk of nocturnal hypoglycemia. Long- acting analogs such as insulin glargine U- 100 reduce thie peek but still exhibit notable inter- day varibility in absorption - a problem compoundeid by differences in insertion site, depte, depte, and local blood.
