Buy Viberzi Online, Eluxadoline, sold under the brand names Viberzi and Truberzi, is a medication taken by mouth for the treatment of diarrhea and abdominal pain in individuals with diarrhea-predominant irritable bowel syndrome (IBS-D). It was approved for use in the United States in 2015. The drug originated from Janssen Pharmaceutica and was developed by Actavis.
Common adverse effects are constipation and nausea, but rates of discontinuation due to constipation were low for both eluxadoline and placebo. Rare adverse effects: fatigue, bronchitis, viral gastroenteritis. Rare serious adverse effects include pancreatitis with a general incidence of 0.3% – higher incidence with 100 mg dose (0.3%) than with 75 mg dose (0.2%). The risk is even greater in those who do not have a gall bladder and the medication is not recommended in this group.
In March 2017, the U.S. Food and Drug Administration issued a safety alert for eluxadoline concerning an increased risk of serious pancreatitis in patients without a gallbladder. An FDA review found that in such patients, spasm of the sphincter of Oddi may lead to severe pancreatitis. The FDA reported that in some cases symptoms have occurred with just one or two doses at the recommended dosage for patients without a gallbladder (75 mg). Of two deaths associated with eluxadoline reported up to February 2017, both occurred in patients without a gallbladder

In the in vitro studies, eluxadoline was found to be transported by OAT3 (SLC22A8), OATP1B1 (SLCO1B1) and BSEP (ABCB11) at the highest concentrations tested (400 ng/ml which is 162-fold larger than the observed Cmax of the highest therapeutic dose of 100 mg). However, it was not to be transported by OCT1 POU2F1, OAT1 Organic anion transporter 1, OCT2, OATP1B3 (SLCO1B3), P-gp (P-glycoprotein), or BCRP (ABCG2)
Multidrug resistance-associated protein 2 (MRP2)-vesicular accumulation of eluxadoline was observed, indicating that the drug is a substrate of MRP2. Eluxadoline was not found to inhibit BCRP-, BSEP-, MRP2-, OCT1-, OCT2-, OAT1-, OAT3-, or OATP1B3-mediated transport of probe substrates but inhibited the transport of probe substrates of OATP1B1 and P-gp. Also in the in vitro studies, it was observed that eluxadoline is an in vivo substrate of OATP1B1, OAT3, and MRP2
