About this study
Official title: A Randomized, Double-blind Clinical Trial Comparing Zegerid Capsule to Famotidine in Preventing Anastomotic (Marginal) Ulcers in Post Gastric Bypass Patients
This research is to determine which medication, Zegerid (Omeprazole/Sodium Bicarbonate) or Pepcid AC (Famotidine), works best at reducing the chance that a patient will get an ulcer after gastric bypass surgery.
Read the detailed description
The purpose of this research is to evaluate information about the control of gastric acid in post gastric bypass surgery patients. Goal is to determine which medication best reduces the incidence of anastomotic ulcers post-operatively.
- Conditions
- Marginal Ulcers
- Being tested
- Omeprazole, Famotidine
- Keywords
- gastric bypass surgery, anastomosis, Roux-en-Y, Complication, Postoperative
- Medical subject headings
- Peptic Ulcer, Postoperative Complications
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
OmeprazoleDrug
Also called Zegerid
40mg dose administered as a suspension or capsule as physician directs daily at bedtime for 14 weeks beginning day of hospital discharge following gastric bypass surgery.
FamotidineDrug
Also called Pepcid
40mg dose administered as a suspension or capsule as physician directs daily at bedtime for 14 weeks beginning day of hospital discharge following gastric bypass surgery.
| Study group | Role | What they receive |
|---|---|---|
| Omeprazole | Active comparator | 40 mg Omeprazole daily Receives: Drug: Omeprazole |
| Famotidine | Active comparator | 40 mg Famotidine daily Receives: Drug: Famotidine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Complaints, Specifically About Pain, Vomiting, Dyspepsia, and/or Dysphagia.
Measured: during first 14 weeks after surgery
Secondary outcomes (1)
Number of Participants With Upper Endoscopy Indicated Due to Complaints
Endoscopic visualization of presence or absence of anastomotic ulcers if upper endoscopy indicated due to patient complaints - based upon severity of complaints
Measured: during first 14 weeks after surgery

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
