E.5 End points |
E.5.1 | Primary end point(s) |
Forty completed visits, two per each of the 20 healthy volunteers during which they ingest codeine and placebo in a randomized double-blind cross-over fashion. Analysis of high resolution impedance manometry (HRiM) data will be performed to study motility patterns in the esophagus and pharynx.
We will compare different HRiM parameters between placebo and codeine condition:
• Distal contractile integral;
• Integrated relaxation pressure;
• Distal latency;
• Pressure flow parameters.

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
starting 45 min after administration of codeine or placebo for esophageal measurements, starting 75 min after administration for pharyngeal measurements |
|
E.5.2 | Secondary end point(s) |
