The Use of Domperidone for Gastroparesis
Monitoring Study for the Use of Gastroparesis for Patient Who Have Failed Standard Therapy
The purpose of this study is to determine whether domperidone can be used safely and effectively for patient with gastroparesis.
Individuals who have been diagnosed with gastroparesis and have failed at least one standard therapy will be offered to trial domperidone as a possible remedy to their condition. Patients on the medication will be expected to to be followed by the physician at 3 months, 6 months 12months, and then annually while on the medication. Any change or significant adverse reaction to the medication or in their condition should be reported immediately to their physician.
