Proton pump inhibitors (PPIs) are usually taken one time a
day. They are sometimes taken two times a day if a stronger dose is needed.
How It Works
Proton pump inhibitors (PPIs) greatly
reduce the amount of acid produced by the stomach, which in turn reduces
irritation of the stomach lining and allows an ulcer to heal.
used with antibiotics, PPIs also help treat Helicobacter pylori (H. pylori) infection.
Why It Is Used
Proton pump inhibitors are used to
treat ulcers. They provide short-term (2 to 8 weeks) treatment for
ulcers in the stomach and in the upper small
PPIs are also used to prevent ulcers and problems from ulcers (such as bleeding) in people who take NSAIDs long-term (for example, for arthritis).
How Well It Works
Proton pump inhibitors (PPIs) can
block more than 90% of stomach acid production. These medicines work better than antacids or H2 blockers to prevent and treat ulcers.
ulcers heal within 4 weeks, although some people may need up to 4 more weeks of
treatment to complete healing. In rare cases, large ulcers need even longer
These medicines have been shown to prevent ulcers and problems from ulcers (such as bleeding) in people who take NSAIDs long-term.1
These medicines generally are
well tolerated. Headache and diarrhea are the most frequent side effects. These
medicines may interfere slightly with the actions of warfarin (Coumadin) and
phenytoin (Dilantin). Tell your doctor about all the medicines you are

What To Think About
Proton pump inhibitors (PPIs)
usually cost more than H2 blockers.
Proton pump inhibitors work best when they are taken 30 minutes before your first meal (for example, breakfast). If taking one pill before breakfast does not completely relieve your symptoms, talk to your doctor about taking another pill before dinner.
