• PRIALT is an N-type calcium channel blocker. The way that PRIALT blocks pain in animals is well understood, but how PRIALT produces this effect in humans is not completely known. It stops pain-sensing nerves from sending pain signals to the brain so that awareness - or, feeling - of pain is reduced or removed
  
  
• PRIALT is made in the laboratory to resemble a peptide in the venom that occurs naturally in the marine sea snail, Conus magus
  
  
• PRIALT is not an opioid. PRIALT therapy can be interrupted or discontinued abruptly without evidence of withdrawal effects. It can be taken with other drugs prescribed for pain relief, such as opioids  

PRIALT is indicated for the intrathecal (IT) treatment and management of severe chronic pain for patients who are intolerant of other treatment options such as analgesics or intrathecal (IT) morphine
