Research Overview
Desmopressin
The literature is mixed, but desmopressin has shown memory-related effects in selected populations and experimental paradigms. Its cognitive effects are usually discussed as a vasopressin-pathway probe rather than a primary nootropic.
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.
