How does ziconotide work?
Ziconotide is a non-opioid analgesic that is prescribed to treat chronic pain that is not relieved by alternate medications. Ziconotide prevents the transmission of pain through the spine by the blocking conduction of pain signals by the nerve cells (neurons).
Ziconotide blocks calcium channels on the surface of neurons and prevents the inflow of calcium ions into the neurons. Blocking calcium channels prevents the release of chemicals (neurotransmitters) that transmit pain signals. Ziconotide is not addictive, being a non-opioid analgesic.
