No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
To evaluate the pharmacodynamics and tolerability of a liquid formulation of lubiprostone, as compared to matching placebo, when administered orally to subjects with chronic idiopathic constipation. Additionally, liquid formulation pharmacokinetics, including a comparison of fed and fasted pharmacokinetics, of the liquid formulation will be performed in a subset of subjects.
