Plecanatide (Trulance) vs Triptorelin (Trelstar)

An educational, source-based comparison of Plecanatide (Trulance) and Triptorelin (Trelstar) — how each peptide works, what it's researched for, and what to know before going deeper.

GC-C Agonist · Gastrointestinal
Plecanatide (Trulance)

Uroguanylin analog for chronic constipation.

Mechanism

Synthetic analog of human uroguanylin that activates guanylate cyclase-C in a pH-dependent manner, increasing intestinal fluid secretion and transit.

Research areas
  • Chronic idiopathic constipation
  • IBS-C
Considerations
  • FDA-approved.
  • Diarrhea most common adverse event.

GnRH Agonist · Oncology
Triptorelin (Trelstar)

GnRH agonist depot for advanced prostate cancer.

Mechanism

Decapeptide GnRH agonist that initially stimulates then desensitizes pituitary GnRH receptors, suppressing LH, FSH, and downstream gonadal steroid production after the initial flare.

Research areas
  • Advanced prostate cancer
  • Central precocious puberty (international)
  • Endometriosis (international)
Considerations
  • FDA-approved.
  • Initial testosterone flare; consider antiandrogen pretreatment.
  • Hot flashes, bone density loss with chronic use.
