DUBLIN, Dec. 19, 2011 /PRNewswire/ -- A panel of experts has recommended changes to the guidelines used to determine treatment via intrathecal administration for patients suffering from severe chronic pain. The 2011 Polyanalgesic Consensus Conference (PACC) brought together a group of national leaders in chronic pain management for the purpose of updating their current algorithm to standardize decision-making among providers and improving the technical quality of care in chronic pain.
The 2011 PACC guidelines for management of nociceptive and neuropathic chronic pain by intrathecal drug delivery recommended ziconotide, among other drugs, as a first-line intrathecal treatment. The panel recognized that ziconotide should be titrated in a low and slow manner. Ziconotide was also recommended by the 2011 group as the preferred option for intrathecal administration compared to opioids when there is a concern for recurrent granuloma.

The expert panel recommendation was based on an extensive literature search and an expansive survey with more than 15,000 clinicians worldwide since the last update in 2007. The panel also reviewed changes in the FDA status of medications and their combined clinical expertise to inform their recommendations
"The Consensus Conference was convened to review the importance of drug selection in patient outcomes; to review issues concerning granuloma detection, prevention and treatment; to consider trialing methods and candidates and to consider best practices to reduce morbidity and mortality," said Tim Deer, MD, president and CEO, The Center for Pain Relief and Clinical Professor of Anesthesiology, West Virginia University School of Medicine, Charleston, WV.
The expert panel of 29 clinicians and the faculty of the North American Neuromodulation Society was convened by Tim Deer, MD, Joshua Prager, MD, MS, Center for the Rehabilitation of Pain Syndromes (CRPS) at UCLA Medical Center, Los Angeles, CA; and Robert Levy, MD, PhD, Northwestern, University, Feinberg School of Medicine, Chicago, IL. The results were presented during the North American Neuromodulation Society Annual Meeting, Dec. 8-11, in Las Vegas, NV.
"The importance of selecting the best drug options for intraspinal drug delivery to treat those in severe pain cannot be understated," added Deer. "We must continue to keep all our colleagues informed of the best treatment practices in pain management and routinely evaluate treatments and patient data. Best clinical practices, experience, data and overall better patient outcomes will remain at the core of the Polyanalgesic Consensus Conference."

About PRIALT(R) (ziconotide intrathecal infusion)
On December 28, 2004, the FDA approved PRIALT for the management of severe chronic pain in patients for whom IT therapy is warranted, and who are intolerant of or refractory to other treatments, such as systemic analgesics, adjunctive therapies, or IT morphine. PRIALT is approved for use only in the Medtronic SynchroMed(R) EL, SynchroMed(R) II Infusion System and the CADD-Micro(R) ambulatory infusion pump.
Mechanism of Action
PRIALT is in a class of non-opioid analgesics known as N-type calcium channel blockers (NCCBs). PRIALT is the synthetic equivalent of a naturally-occurring conopeptide found in a marine snail known as Conus magus. Research in animals suggests that the mechanism of action of PRIALT works by targeting and blocking N-type calcium channels on nerves in the spinal cord that ordinarily transmit pain signals.
Dosing and Administration
PRIALT is administered through microinfusion devices (pumps) delivering the drug into the fluid surrounding the spinal cord. Typically, these pumps are implantable, programmable, variable rate microinfusion devices, but external pumps may be used for initial or shorter-term treatment. The current dosing and titration schedule for PRIALT was optimized based on the final phase III pivotal trial. In the slow titration study, the initial dosing was lowered and the rate of titration was reduced in both frequency and dosage increments compared with previous clinical trials. Treatment should be initiated at a delivery rate of 2.4 mcg/d (0.1 mcg/h) or less. Titration increments should be 2.4 mcg/d or less, and increases should be made 1, 2, or no more than 3 times per week. FDA approval of PRIALT was based on the treatment of more than 1,200 patients included in the 3 phase III trials, which evaluated the efficacy and safety of PRIALT in patients with severe chronic pain that was not adequately managed with a regimen of systemic and/or IT analgesic and other drugs. These trials involved a variety of patient populations, including patients with pain related to failed back surgery, cancer, AIDS, and non-malignant causes.
PRIALT has been evaluated as an IT infusion in more than 1,200 patients participating in chronic pain trials.
Severe psychiatric symptoms and neurological impairment may occur during treatment with PRIALT. Patients with a pre-existing history of psychosis should not be treated with PRIALT. All patients should be monitored frequently for evidence of cognitive impairment, hallucinations, or changes in mood or consciousness. PRIALT therapy can be interrupted or discontinued abruptly without evidence of withdrawal effects in the event of serious neurological or psychiatric signs or symptoms.
Because PRIALT is a non-opioid, it does not react with opiate receptors and does not potentiate opiate-induced respiratory depression. Dosage titration can be tailored to patient needs without the risk of dependency or tolerance. The most frequently reported adverse events (greater-than-or-equal-to 25%) in clinical trials (N=1,254) were dizziness, nausea, confusional state and nystagmus. In the slow titration PRIALT study (N=220), asthenia, ataxia, CK increase, abnormal gait, confusion, diarrhea, dizziness, headache, memory impairment, nausea, somnolence, and vomiting were the most commonly reported AEs in the PRIALT group (³10%).
