Eluxadoline Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Eluxadoline, originally developed
by Janssen and currently marketed by Allergan (formerly
Actavis), was approved in May 2015 by the FDA for the
treatment of diarrhea-predominant irritable bowel syndrome
(IBS-D). Eluxadoline, an orally dosed agent, employs a
unique mechanism for IBS-D treatment, as it functions
simultaneously as a μ- and κ-opioid receptor agonist and a δ-
opioid receptor antagonist, leading to a first-in-class therapy
for treatment of IBS-D. Specifically, in animal studies,
eluxadoline was found to interact with opioid receptors in the
gut, inhibiting neurogenically mediated secretion and reducing
intestinal contractility. Additionally, the treatment led to a
decrease in stress-induced acceleration of upper GI transit
without causing rebound constipation, earning its mark as
a first-line therapeutic treatment for IBS-D. In two phase III
clinical trials of over 2400 patients with IBS-D, patients taking
eluxadoline showed a greater improvement toward the end
point (≥30% improvement from their baseline IBS-D score on
at least 50% of days treated with eluxadoline) compared to
patients treated with placebo.
Verwenden
Eluxadoline is an orally-active drug used to reduce symptoms of irritable bowel syndrome such as diarrhea and abdominal pain.
Definition
ChEBI: An amino acid amide obtained by the formal condensation of the carboxy group of 4-carbamoyl-2,6-dimethyl-L-phenylalanine with the secondary amino group of 2-methoxy-5-({[(1S)-1-(4-phenylimidazol-2-yl)ethyl]amino}methyl)ben
oic acid. It has mixed opioid receptor activity and is used for treatment of irritable bowel syndrome with diarrhoea.
Pharmakokinetik
Following oral administration of 100 mg VIBERZI in healthy subjects, the Cmax of eluxadoline was approximately 2 to 4 ng/mL, and AUC was 12 to 22 ng. h/mL. Eluxadoline has approximately linear pharmacokinetics with no accumulation upon repeated twice-daily dosing. The variability of eluxadoline pharmacokinetic parameters ranges from 51% to 98%.
Absorption: The absolute bioavailability of eluxadoline has not been determined. The median Tmax value was 1.5 hours (1 to 8 hours) under fed conditions and 2 hours (range: 0.5 to 6 hours) under fasting conditions.
The administration of VIBERZI with a high-fat meal that contained approximately 800 to 1000 total calories, with 50% of calories derived from fat content, decreased the Cmax of eluxadoline by 50% and AUC by 60%.
Distribution: Plasma protein binding of eluxadoline was 81%.
Elimination: The mean plasma elimination half-life of eluxadoline ranged from 3.7 hours to 6 hours.
Metabolism: The metabolism of eluxadoline is not established. There is evidence that glucuronidation can occur to form an acyl glucuronide metabolite.
Excretion: Following a single oral dose of 300 mg [14C] eluxadoline in healthy male subjects, 82.2% of the total radioactivity was recovered in feces within 336 hours and less than 1% was recovered in urine within 192 hours.
