Examples

Prokinetic agents are taken by mouth (orally) in pill or liquid form (Reglan syrup).

How It Works

Prokinetic agents:

• Make the valve between the esophagus and stomach (lower esophageal sphincter) squeeze shut more tightly. This makes it harder for stomach acid and juices to back up, or reflux, into the esophagus.
• Make the stomach empty quicker, which reduces the amount of acid in the stomach.

Why It Is Used

Prokinetic agents are used to treat heartburn caused by gastroesophageal reflux disease (GERD). Prokinetic agents may be used along with H2 blockers (acid reducers) to help clear stomach juices from the esophagus and stomach.

How Well It Works

Prokinetic agents can be effective when used with H2 blockers but are not the first choice for treating GERD symptoms because proton pump inhibitors usually work better and have fewer side effects.

Side Effects

More than 30% of the people taking metoclopramide have side effects.¹ These include:

• Nausea.
• Diarrhea.
• Nervous system side effects, such as jumpiness, confusion, or sleeplessness. These occur in 20% to 40% of people who take the medication.²

Metoclopramide is known to have interactions with other medications. Talk to your doctor about taking metoclopramide if you are also taking other medications.

In some people, metoclopramide may cause depression. It can also cause shaking or trembling (parkinsonian-like symptoms) and involuntary movements of the facial muscles and tongue (tardive dyskinesia).

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

What To Think About

Prokinetic agents are not usually used to treat GERD. H2 blockers or proton pump inhibitors are more commonly used.

Some doctors may prefer to use a combination of a prokinetic drug and an H2 blocker to treat GERD symptoms before using a proton pump inhibitor. But this may cost more than using a proton pump inhibitor alone.
