Lubiprostone as a Treatment for Constipation in Parkinson's Disease
Stopped early · Not applicable
Conditions studied: Constipation, Parkinson's Disease
In brief
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)
