Synthetic Secretin (ChiRhoStim) vs Ziconotide (Prialt)

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

Diagnostic · Gastroenterology
Synthetic Secretin (ChiRhoStim)

27-amino-acid peptide used to stimulate pancreatic secretions for diagnosis.

Mechanism

Synthetic human secretin that stimulates pancreatic bicarbonate, fluid secretion, and gastrin release — used diagnostically for pancreatic function, gastrinoma evaluation, and ERCP facilitation.

Research areas
  • Pancreatic function testing
  • Gastrinoma (Zollinger-Ellison) diagnosis
  • ERCP facilitation
Considerations
  • FDA-approved.
  • Single diagnostic dose; minimal adverse effects.

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.
