Effect of Citalopram on Reflux Episodes in Healthy Volunteers
- Registration Number
- NCT03746691
- Lead Sponsor
- Universitaire Ziekenhuizen KU Leuven
- Brief Summary
Citalopram is sometimes used in the treatment for gastro-esophageal reflux disease, however, there are no empirical data to support this. The investigators would like to know if citalopram has an effect on the lower esophageal sphincter pressure, transient lower esophageal sphincter relaxations and reflux episodes. The investigators will investigate this by performing high resolution impedance manometry in healthy volunteers before and after a solid meal. This will be compared to placebo, in a cross-over, randomized, double-blind condition.

Group Intervention Description Placebo, IV Placebos After placement of a high resolution impedance manometry catheter (transnasally), placebo (saline 100ml) will be administered IV over 30 minutes. Thereafter, the investigators will wait for 20 minutes, after which the volunteers will receive 10 wet swallows (5ml saline), to investigate esophageal peristalsis. Thereafter, a standard meal (1000kcal) will be given to the volunteers and recordings will continue for another 2 hours. Citalopram, 20 mg, IV Citalopram HCl After placement of a high resolution impedance manometry catheter (transnasally), citalopram will be administered IV over 30 minutes (20 mg in 100ml saline). Thereafter, the investigators will wait for 20 minutes, after which the volunteers will receive 10 wet swallows (5ml saline), to investigate esophageal peristalsis. Thereafter, a standard meal (1000kcal) will be given to the volunteers and recordings will continue for another 2 hours.
- Primary Outcome Measures
Name Time Method Change in LES pressure LES pressure will be measured for 4 times (a 5 sec time window) per hour. The average of the first hour will be taken as the LES pressure for the first hour postprandially. The investigators will measure lower esophageal sphincter pressure after a meal between placebo and citalopram, using a high resolution impedance manometry system. LES pressures will be measured in the first hour postprandial and will be compared (preprandial vs postprandial hour 1).
Change in the number of TLESRs The total number of TLESRs will be counted in a 3 hour time period, to have 1 number of TLESRs. The investigators will measure the number of transient lower esophageal sphincter relaxations after a meal between placebo and citalopram, using a high resolution impedance manometry system.
Change in the number of reflux episodes The number of reflux episodes will be counted in a 3 hour time period, to have 1 number of reflux episodes. The investigators will measure the number of reflux episodes after a meal between placebo and citalopram, using a high resolution impedance manometry system.
