Summary of Clinical Use Click here for help
Ziconotide (Prialt®) is an approved drug that is indicated for the management of severe chronic pain [6] in patients for whom intrathecal (IT) therapy is warranted and who are intolerant of or refractory to other treatment, such as systemic analgesics, adjunctive therapies, or IT morphine.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
ω-conotoxins are selective N-type voltage-gated calcium channel (VGCC, Cav2.2) antagonists [1]. Ziconotide is a synthetic analogue of this naturally occurring compound. It behaves as a non-narcotic pain reliever, with its MMOA also attributable to VGCC blockade. Blocking the activity of these ion channels impedes excitatory neurotransmitter release in primary afferent nerve terminals and is antinociceptive [4].
