Outcomes

Primary Outcomes

Change From Baseline High Resolution Esophageal Manometry With Impedance to Day 7

The high resolution esophageal manometry with impedance involves a thin, pressure-sensitive tube that is passed through the nose and into the stomach. Once in place, the tube is pulled slowly back into the esophagus (food pipe). When the tube is in the esophagus, the patient is asked to swallow several times while swallowing water, applesauce, crackers, and marshmallows. These swallows will be completed while laying down, sitting upright, and standing. The pressure of the muscle contractions will be measured along several sections of the tube. The tube is removed after the tests are completed. This test allows for a quantitative measure of the pressure in the esophagus that can be correlated to difficulty or ease of bolus swallowing.

Time frame: Day 1 and Day 7

Secondary Outcomes

Change From Baseline Evaluation of Esophageal Function Questionnaire to Day 7

This questionnaire allows the patient to assess their own symptoms and report their opinions about drug effectiveness.

Time frame: Day 1 and Day 7
