Ziconotide

Ziconotide (SNX-111, marketed as Prialt) is a synthetic form of ω-conotoxin MVIIA, a 25-amino acid peptide originally isolated from the venom of the marine cone snail Conus magus. It is a potent and selective blocker of N-type voltage-gated calcium channels (Cav2.2/CACNA1B), which are critical for neurotransmitter release at primary afferent nerve terminals in the spinal cord dorsal horn. By blocking these channels, Ziconotide provides powerful analgesia through a non-opioid mechanism, making it FDA-approved (2004) for the management of severe chronic pain in patients who are intolerant or refractory to other treatments. It requires intrathecal administration due to inability to cross the blood-brain barrier.
