Eluxadoline (INN, USAN) (brand name Viberzi vye-BER-zee; former developmental code name JNJ-27018966) is an orally-active drug approved for the treatment of diarrhea and abdominal pain in individuals with diarrhea-predominant irritable bowel syndrome (IBS-D). It was approved for use by the United States Food and Drug Administration on May 27, 2015. The drug originated from Janssen Pharmaceutica and was developed by Actavis.
Mechanism of action
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. Finally, no inhibition or induction of cytochrome P450 enzymes was observed.
Following a 100 mg dose of eluxadoline, the Cmax was about 2 to 4 ng/ml and AUC was 12-22 ng.h/ml. Eluxadoline has linear pharmacokinetics with no accumulation upon repeated twice daily dosing. Taking eluxadoline with high fat meal decreased the Cmax by 50% and AUC by 60%.
Dosing and administration
Eluxadoline is available as 75 and 100 mg in the form of tablets.
Elevated concentrations of eluxadoline were observed with coadministraion of OATP1B1 inhibitors such as:
Also, concurrent use of other drugs that cause constipation is not preferred, such as:
Common adverse effects in the two phase III clinical trials were 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 effect in a clinical trial was pancreatitis with a general incidence of 0.3% - higher incidence with 100 mg dose (0.3%) than with 75 mg dose (0.2%).
This drug should not be taken in case of having:
- Blockage of the gallbladder or a sphincter of Oddi problem
- Problems with alcohol abuse
