Patient-controlled, transdermal pain management system comparable to IV PCA morphine after gynecologic surgery
Researchers own tittle-tattle that IONSYSTM, a innovative patient-controlled, transdermal, analgesic tortuous that deliver fentanyl through the buckskin, may be comparable to intravenous
patient-controlled analgesia (IV PCA) when once own after gynecologic surgery. This needle-free system in support of managing acute tender contained by means of the infirmary surroundings be at the
moment downwards consideration by the Food and Drug Administration (FDA), and be granted approvable snob value in June, 2004. These facts be presented at the American Society of Regional Anesthesia
& Pain Medicine Annual Fall Pain Meeting.
Dr. Carr and his colleagues are prompted by grades from a recent clinical trial showing the worth of a as good as technique opposed to advanced liver cancer. Reporting only just in the publication
Hepatology, Dr. Carr and physician at Northwestern University in Chicago found that injecting another type of Yttrium-90-containing beads (TheraSphere) be distinctive in treating inoperable liver
cancer even in patients whose portal capillary was closed by tumor. The treatment, he vote, was as commendable as or better than using the connected ensign called chemoembolization, which necessity
directly injecting chemotherapy drugs into the liver through the hepatic artery. Because it involves unpredictable, cell-killing drugs, he notes, doctors particular sought liver cancer treatment
that have a lesser amount of noxious effects.
Researchers reported no statistically-significant lack of correspondence relating the two line of attack in patients’ overall pain order, the amount of supplemental pain medication unavoidable, or
the digit of patients withdrawing from the study in the red to deficient pain relief. Side effects were similar in both pack.
“In 2002, in being there were higher than a million gynecologic surgeries perform in the United States,” said Shireen Ahmad, M.D., Assistant Professor, Department of Anesthesiology at Northwestern
University. “In this subanalysis, IONSYSTM bring in post-operative pain relief to furthermost patients undergo gynecologic surgery in have need of the needles, lines and pump needed for IV PCA.”
Patients in the study were randomized to receive either IONSYSTM - which delivers 40 micrograms of fentanyl on pressure, able to six dose per hour - or one milligram of morphine on demand, up and
about to 10 doses per hour, via IV PCA.
Among 275 women undergoing gynecologic surgery, 85% of IONSYSTM patients, or 117 of 138, and 84% of IV PCA patients, or 115 of 137, rate their pain control as consummate or fair during the first 24
hours of physiotherapy (p0.848). Patient measurements of pain depth were similar between IONSYSTM and the IV PCA groups at four and at eight hours, and also at the state-of-the-art pain intensity
rack up. A similar shear of patients in respectively group request supplemental pain medication during the first three hours of treatment, 18.1% of IONSYSTM patients and 21.2 % of IV PCA patients.
Inadequate pain relief resulted in the presumption of 8.7% or 12 patients in the IONSYSTM group and 4.4% or 6 patients in the IV PCA group. The rate of adverse accomplishments was similar in
IONSYSTM and IV PCA groups, respectively. Nausea 50% vs. 57%, headache 19% vs. 10%, itching 11% vs. 15%, and vomiting 9% vs. 6%, were the most rife.
IV PCA system, which be currently used to administer medication for acute pain in the hospital setting, consist of a programmable contrivance, a ship`s mast and connective tubing, which are
attached to the tolerant via an intravenous stripe into their arm. By judgment, IONSYSTM is a lightweight, compact system, something approaching the proportions of a appreciation card that adhere
to a patient’s upper arm or treasure chest. When a dose of pain medication is needed, the patient pressurize a key to be found on the system. This generate a exceptionally low-intensity electrical
current - not perceive by the patient - that delivers a pre-programmed dose of fentanyl through the skin. The medication is immersed into the section ended a 10-minute lull.
IONSYSTM is predestined for operate only in medical institution, such as hospital and surgical centers, by patients under medical admin and direction.
IONSYSTM contain fentanyl, an opioid agonist and a Schedule II controlled voluminous ends with illustrious soon-to-be for oral abuse resembling hydromorphone, methadone, morphine and oxycodone.
Fentanyl can be abused in a deportment similar to other opioid agonists, legitimate or illicit. This should be considered in situation where on loam the healthcare executive is upset something like an increased hazard of misuse, abuse or relaxation. Fentanyl can garden high spirits nerve-racking respiratory
reduction. Inappropriate use of IONSYSTM, or unintended bringing to light to the fentanyl gel inwardly the system, could coordinate to the incorporation of a potentially mortal dose of fentanyl.
Therefore, the fentanyl gel should not be permitted to soupcon the finger or orifice. Oral experience or ingestion of the fentanyl-containing gel may cause life-threatening hypoventilation or
demise.
The ALZA Corporation, headquartered in Mountain View, California, built-up the E-TRANS transdermal technology used in IONSYSTM. ALZA is serviceable to complete the stepladder fundamental for
concluding marketing pronouncement in the United States, following reception of the approvable missive from FDA. Once certified, Ortho-McNeil Pharmaceutical, Inc. will flea market the system in the
United States.
Janssen-Cilag will market IONSYSTM in Europe; a marketing authorization submission was submit to the European Medicines Agency in June 2004. Ortho-McNeil, ALZA and Janssen-Cilag are Johnson &
Johnson camaraderie.
