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.
Epoetin Alfa
Human studies in anemia and performance-related settings show that increasing red-cell mass can improve aerobic capacity and endurance. It remains heavily regulated because excessive erythropoiesis raises thrombotic and cardiovascular risk.
