Ziconotide TEA acts by binding to N-type calcium channels situated on the terminal part of primary afferent neurons of the nociceptive pathway therefore reducing synaptic transmission with potent antinociceptive effects.
Ziconotide is an atypical analgesic agent for the amelioration of severe and chronic pain. Derived from Conus magus, a cone snail, it is the synthetic form of an ω-conotoxin peptide.
