Acid Reflux Study – Bravo® Method

Bravo® is a recording capsule. It tests acid levels in the esophagus to help detect gastric reflux. It is attached to the esophagus during the endoscopy.

Once attached, it sends readings to a monitor that you carry. This will record all acid readings for the next 48 hours. Two days before, you will begin keeping a diary of when you eat and drink. Record when you are laying down, and any symptoms you have.

Getting Ready

If you are taking medicine to reduce stomach acid, stop taking them. 

(see list below). 

  • 14 days before, stop: Nexium® (esomeprazole).

  • 7 days before, stop: Aciphex® (rabeprazole), Protonix® (pantoprazole). Prilosec® (omeprazole), Prevacid®(lansoprazole).

  • 2 days before, stop: Propulsid® (cisapride), Zantac® (ranitidine), Axid® (nizatidine), Pepcid® (Famotidine), and Tagamet® (cimetidine).
