Triptorelin (Trelstar) vs Ziconotide (Prialt)

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

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.

N-type Calcium Channel Blocker · Analgesic
Ziconotide (Prialt)

Synthetic ω-conopeptide for severe chronic pain via intrathecal infusion.

Mechanism

Synthetic version of ω-conotoxin MVIIA from cone snail Conus magus; selectively blocks N-type voltage-gated calcium channels on primary afferent nerve terminals in the spinal dorsal horn, inhibiting nociceptive neurotransmitter release.

Research areas
  • Severe chronic pain refractory to systemic analgesics, intrathecal morphine
Considerations
  • FDA-approved.
  • Black-box warning for severe psychiatric and neurologic effects.
  • Contraindicated in history of psychosis.
