Research Overview

Insulin Aspart

Research consistently shows faster onset and earlier peak action than regular human insulin. It is commonly studied for meal-time glycemic control and pump-based insulin delivery.

Plecanatide

Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
