Rezafungin (Rezzayo) vs Ziconotide (Prialt)
An educational, source-based comparison of Rezafungin (Rezzayo) and Ziconotide (Prialt) — how each peptide works, what it's researched for, and what to know before going deeper.
Once-weekly echinocandin for candidemia and invasive candidiasis.
Next-generation echinocandin structurally related to anidulafungin with enhanced stability, inhibiting β-(1,3)-D-glucan synthase; long half-life permits once-weekly IV dosing.
- Candidemia
- Invasive candidiasis
- • FDA-approved (2023).
- • Infusion reactions and photosensitivity reported.
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.
