OP2C : Prialt® Observatory in Clinical Practice


Ziconotide is a powerful analgesic marketed since 2009 in France and reserved for the intrathecal route.

It is particularly effective on neuropathic pain and its main advantages are its power of action, the absence of spinal toxicity and the absence of respiratory depression. In addition, there were no signs of withdrawal when stopping the drug or tachyphylaxis.

However, during these studies many undesirable effects were highlighted, especially neuropsychic which limited its use. This toxicity was mainly related to the administration of too high doses.

In recent years, the use of ziconotide intrathecally has again become a relevant option. Indeed, it is recommended as a first line in the intrathecal treatment options.

However, there is a lack of data on the current use of ziconotide in current practice.

The objective of the study will be to describe the practical methods of using intrathecal treatments containing ziconotide.
