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.
27-amino-acid peptide used to stimulate pancreatic secretions for diagnosis.
Synthetic human secretin that stimulates pancreatic bicarbonate, fluid secretion, and gastrin release — used diagnostically for pancreatic function, gastrinoma evaluation, and ERCP facilitation.
- Pancreatic function testing
- Gastrinoma (Zollinger-Ellison) diagnosis
- ERCP facilitation
- • FDA-approved.
- • Single diagnostic dose; minimal adverse effects.
Synthetic ω-conopeptide for severe chronic pain via intrathecal infusion.
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.
- Severe chronic pain refractory to systemic analgesics, intrathecal morphine
- • FDA-approved.
- • Black-box warning for severe psychiatric and neurologic effects.
- • Contraindicated in history of psychosis.
