What is PRIALT?

PRIALT® (ziconotide) intrathecal infusion is an analgesic that is administered directly into the spinal fluid via a pump.1,2,3 The Food and Drug Administration (FDA) has approved PRIALT for use in adults with severe chronic pain when other treatments have proven to be ineffective or intolerable.1

PRIALT is a non narcotic pain management option that may be able to relieve severe chronic pain.2,4

How does PRIALT work?

PRIALT binds to the N-type calcium channels located in the dorsal horn of the spinal cord, blocking the release of excitatory neurotransmitters, which leads to antinociception (as seen in animal studies).1

Studies have demonstrated that PRIALT1:

  • Does not bind to opioid receptors, and its pharmacological effects are not blocked by opioid antagonists.
  • Did not potentiate morphine-induced respiratory depression in animal models.
  • Concurrent administration of IT ziconotide and morphine did not prevent the development of morphine tolerance in rats.5
