Research Overview

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.

Cetrorelix

Cetrorelix is a cornerstone GnRH antagonist in assisted reproduction, with a fast onset and reversible suppression of LH. Trials show it improves cycle management by reducing premature ovulation during stimulation.
