Patient Education: Manometry

Esophageal manometry is a test used to measure the function of the lower esophageal sphincter (the valve that prevents reflux of gastric acid into the esophagus) and the muscles of the esophagus (see diagram). This test will tell your doctor if your esophagus is able to move food to your stomach normally. To know why you might be experiencing a problem with your digestive system, it helps to understand the swallowing and digestive processes.

Preparation

One day (24 hours) before the test, stop taking calcium channel blockers such as Calan®, Isoptin® (verapamil); Adalat®, Pro-cardia® (nifedipine); and Cardizem®(diltiazem). Also stop taking nitrate and nitroglycerin products such as Isordil® (isosorbide); Nitrobid®, Nitrodisc®, Nitrodur®, Nitrogard®, Transderm-Nitro®, and Tridil®

Twelve hours before the test, do not take sedatives such as Valium® (diazepam) or Xanax® (alprazolam).

Do not stop taking any other medication without first talking with your doctor.

Do not eat or drink anything 4 to 6 hours before the test.
