Research Excerpts

Overview

Lesogaberan (AZD3355) is a novel reflux inhibitor developed as an add-on treatment to proton pump inhibitors (PPIs) for symptom relief in patients with gastroesophageal reflux disease who have a partial response to PPI therapy.

Pharmacokinetics

Lesogaberan is being developed as an add-on treatment for the management of patients with GERD who have a partial response to proton pump inhibitor (PPI) therapy. There was no observed pharmacokinetic interaction when concomitantly administered to healthy subjects.

ExcerptReferenceRelevance
" As lesogaberan is being developed as an add-on treatment for the management of patients with GERD who have a partial response to proton pump inhibitor (PPI) therapy, it is important to rule out any clinically important pharmacokinetic drug-drug interaction between lesogaberan and PPIs."( Evaluation of the pharmacokinetic interaction between lesogaberan (AZD3355) and esomeprazole in healthy subjects.

Bioavailability

lesogaberan is rapidly absorbed with high bioavailability. Most of the dose is excreted by the kidneys either as the parent compound or as metabolites. The effect of food on the bioavailability of this compound has not been assessed.
