Advice for healthcare professionals:
eluxadoline (Truberzi▼), licensed for irritable bowel syndrome with diarrhoea, should be initiated and supervised by a specialist physician experienced in diagnosis and management of gastrointestinal disorders
do not use in patients without a gallbladder or in patients with known or suspected biliary tree or pancreatic duct obstruction (eg, gallstones, tumour, periampullary duodenal diverticulum) or sphincter of Oddi disease or dysfunction
tell patients to avoid drinking alcohol during treatment with eluxadoline
inform patients about symptoms suggestive of pancreatitis—eg, abdominal pain that may radiate to the back or shoulder, nausea, and vomiting
instruct patients to stop taking eluxadoline and seek immediate medical attention if these symptoms develop
report all suspected adverse drug reactions to Black Triangle drugs such as Truberzi to the Yellow Card Scheme
Eluxadoline (Truberzi▼) was approved in 2017 for the treatment of irritable bowel syndrome with diarrhoea (IBS-D) in adults.
On 30 August 2017, the National Institute of Health and Care Excellence (NICE) recommended that eluxadoline could be prescribed on the NHS in England if other pharmacological treatments for IBS-D did not work or were unsuitable and if it was started in secondary care. Use of eluxadoline in the UK is so far extremely low (it is approximated that no more than 20 patients in the UK have started the medicine).
Cases of pancreatitis in patients taking eluxadoline
A routine European review identified 230 cases of, or reactions suggestive of, pancreatitis in patients taking eluxadoline over an estimated exposure of 26,363 patient-years. All cases of pancreatitis came from the USA where, before April 2017, a contraindication in patients without a gallbladder was not in place. Gallbladder status was known in 140 of the cases and of these, most (76%) had undergone cholecystectomy and did not have a gallbladder. Of these, 4 cases were severe: 2 cases in which eluxadoline appears to have contributed to the patient’s death, 1 case of necrotising pancreatitis with an unknown outcome, and 1 case involving acute kidney injury due to dehydration and acute respiratory insufficiency due to atelectasis, which were suspected to have been secondary to pancreatitis. Dehydration and pulmonary complications of acute pancreatitis have been reported in the literature.
Most of the reported cases of pancreatitis occurred within 1 week of starting treatment with eluxadoline and some patients developed symptoms even after 1 to 2 doses. However, cases of pancreatitis after longer duration of treatment have also been reported.
In most cases, eluxadoline treatment was withdrawn. At the time of review, out of the reports with an outcome reported (123 reports), most patients (107) had recovered from the pancreatitis or their condition was improving.
