  Purpose

Delayed colonic transient time secondary to a multi-degenerative process is the most likely cause of constipation in idiopathic PD. Since lubiprostone demonstrated its ability to accelerate colonic transit time in healthy volunteers in addition to activating the chloride channels in the intestinal cells, it has the potential to improve constipation in patients with PD with no subsequent adverse events on the control of the neurological manifestation of PD. So we hypothesize the following:

  1. Lubiprostone will improve ratings on the Bristol stool form scale (BSFS) in patients with PD induced constipation compared to baseline.(primary)
  2. Lubiprostone will increase the number of spontaneous bowel movements (SBM) per week, compared to baseline. (secondary)
  3. Lubiprostone will improve health related quality of life in subjects with PD induced constipation. ( secondary)

Primary Outcome Measures:
  • Average Bristol Stool Form Scale (BSFS) at Baseline, End of 4 Weeks and End of 6 Weeks [ Time Frame: up to 6 weeks ] [ Designated as safety issue: No ]
    The average BSFS will be determined at baseline (prior to the start lubiprostone) and compared with average rating of BSFS at end of the 4 weeks of treatment with Lubiprostone and at end of 2 weeks after stopping the Lubiprostone. BSFS is scale between 1-7, it measured the shape of the stool. BSFS is a scale between 1-7, where 1 correlates with the firmest stool and 7 correlates with entirely liquid stool. Measure was reported at end of week #1-Baseline-,end of Week #5 ( after taking the lubiprostone for 4 weeks) and end of week # 7 ( end of 2 weeks after stopping the Lubiprostone).


Secondary Outcome Measures:
  • Average Number of Spontaneous Bowel Movements (SBM) Per Week [ Time Frame: up to 6 weeks ] [ Designated as safety issue: No ]
    Average number of spontaneous bowel movements (SBM) per week,measured at baseline, at end of 4 weeks of treatment with Lubiprostone and at 2 weeks after stopping Lubiprostone (( so measure was reported at end of week # 1-Baseline-,end of Week #5 ( after taking the lubiprostone for 4 weeks) and end of week # 7 ( end of 2 weeks after stopping the Lubiprostone)).
