Detailed Description:

This is a multicentre, randomised, Phase III trial with a parallel-group design, consisting of a 2 week drug-free run-in period, followed by a 4-week, double-blind, placebo-controlled treatment period.

During the run-in period, the subject's bowel habit will be documented and the existence of constipation confirmed. At the start of this period, all existing laxative medication will be withdrawn and subjects will be instructed not to change their diet or lifestyle during the trial.

Subjects will be allowed to take a laxative (Dulcolax®) as a rescue medication throughout the trial, but only if they have not had a bowel movement for three or more consecutive days. Subjects will enter the double-blind period if constipation is shown to be present during the run-in period. Patients will be randomly allocated to one of the 4 treatment arms: 1 mg, 2 mg, 4 mg of R108512 or placebo, with a 25% chance to each treatment group.

During the double-blind period, subjects will be treated for 4 weeks with either 1 mg, 2 mg or 4 mg R108512 or placebo, given once daily before breakfast.

  3. Subjects with the main complaint of abdominal pain.
  4. Subjects with a known megacolon/megarectum or a diagnosis of pseudo-obstruction.
  5. Constipation as a result of surgery.
  6. Known or suspected organic disorders of the large bowel, i.e. obstruction, carcinoma, or inflammatory bowel disease.
  7. Malignancies or AIDS.
  8. Known serious illnesses: clinically significant cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurological, psychiatric or metabolic disturbances. Patients with known diverticulosis may be included.
