Brief Summary

Gastroparesis (slow stomach emptying) is a common feature of Parkinson's Disease. Levodopa (Sinemet), a common medication for Parkinson's Disease, can make gastroparesis worse. Gastroparesis effects how the levodopa is absorbed and used by the body. This study will explore the possibility of using Erythromycin, a drug commonly used (off label) for gastroparesis, along with levodopa to determine if there is improved levodopa absorption and motor function.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects must have a definitive diagnosis of Parkinson's Disease (per United Kingdom brain bank criteria), Hoehn and Yahr stage 1-3,
  • must exhibit unequivocal levodopa responsiveness
  • must be able to distinguish between the "off" versus "on" state
  • Subjects must be on a stable dose of levodopa for at least 28 days prior to enrollment and should be anticipated to maintain a stable dose throughout both study periods
  • Subjects may be on concomitant therapy with Monoamine oxidase B inhibitors, entacapone, and amantadine, though the doses of these medications must have remained stable for at least 28 days prior to enrollment and must be expected to remain stable throughout both study periods.

You may not qualify if:

  • History of deep brain stimulation for Parkinson Disease
  • History of ablative (tissue removal) surgery for Parkinson Disease
  • Presence of dementia (MMSE\<25)
  • Presence of active psychosis
  • History of any chronic gastrointestinal diseases
  • History of any prior gastrointestinal surgeries except for appendectomy, cholecystectomy, and hysterectomy
  • Any gastrointestinal surgeries in the past 3 months
  • Severe dysphagia (difficulty swallowing) to pills or food
  • History of physiological or mechanical gastrointestinal obstruction
  • History of strictures or fistulae (abnormal or narrow connections) along the gastrointestinal tract
  • History of gastric bezoars (undigested mass)
  • Allergy to wheat, soy, milk, or nuts
  • Presence of portable electromechanical devices such as pacemaker, defibrillator, or infusion pump
