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.
Ziconotide
Clinical studies and post-marketing data support ziconotide as an analgesic for severe chronic pain that does not respond to conventional therapy. Research focuses on balancing analgesic efficacy with neuropsychiatric tolerability and careful dose titration.
