An escalating dose of prucalopride up to a maximum of 20 mg was given once daily to 32 healthy volunteers to determine safety at the maximum tolerable dose or at 20 mg.
This is a single-centre, double-blind, placebo-controlled, cross-over trial in 32 healthy volunteers with two sessions (I and II). Each session consists of a run-in day for baseline assessments, 13 treatment days and 5 additional days for assessments. Subjects will be randomized to start with either the prucalopride or placebo session.
Between the 2 sessions, there will be a washout period of 14 to 21 days, to avoid any carry-over effect.
