title: A double-blind placebo-controlled trial of BRL 24924 on lower oesophageal sphincter pressure and gastro-oesophageal reflux in healthy volunteers.
abstract: BRL 24924 is a new gastrointestinal prokinetic agent with properties similar to metoclopramide but with increased potency and devoid of side-effects associated with blockade of dopamine receptors in the central nervous system. A double-blind placebo-controlled trial of the effect of a single oral dose of 2.2 mg BRL 24924 on lower oesophageal sphincter pressure and gastro-oesophageal reflux has been performed in 20 healthy volunteers. BRL 24924 significantly increased mean lower oesophageal sphincter pressure (21.9 cmH2O BRL; 15.9 cmH2O placebo: P less than 0.017) but failed to alter either the frequency or the duration of gastro-oesophageal reflux after provocation following a test meal. BRL 24924 has significant effects on lower oesophageal sphincter pressure but no effect on provoked post-prandial reflux in healthy volunteers. Further studies in patients with gastro-oesophageal reflux and oesophagitis are needed to evaluate the clinical efficacy of this compound.
