Ziconotide — Uses, Dosage, Side Effects & Safety

Drug class: Pain Relief & Analgesics

Overview

Ziconotide is a prescription medication used to manage severe chronic pain in adults who require intrathecal (spinal) therapy and for whom other treatments have not provided adequate relief or are not tolerated. It is especially useful for pain related to cancer, neuropathic pain, or pain that is resistant to opioid medications. Ziconotide works by blocking specific calcium channels (N-type) in nerves within the spinal cord, which helps to interrupt pain signals before they reach the brain. Unlike opioids, ziconotide does not cause dependence or respiratory depression, making it a valuable option for certain patients. Key points: Ziconotide is administered only by a healthcare professional directly into the spinal fluid using a special pump. It is not suitable for everyone and requires careful monitoring due to potential side effects, especially on mood and mental status.
