Proton pump inhibitors (PPIs) are common medications used to treat conditions like chronic heartburn or GERD. As implied by the name, all PPIs are similar to one another in how they work. PPIs dosages are generally once a day as their effects are meant to last for 24 hours, and because most are metabolized in the liver, you will want to avoid drinking alcohol while taking them. While these medications are similar, they do differ in what conditions they treat and how they interact with other medications.

Comparison of Common Proton Pump Inhibitors (PPIs)

Here is a comprehensive list of common proton pump inhibitors, the conditions they treat, and how they are available.

Long-Term Use of Proton Pump Inhibitors

On a general note, PPIs are not meant to be taken for long periods of time even though they are available over-the-counter. Recent research has associated chronic use of these medications to heart attack, kidney disease, and increased fracture risk. Always speak to your healthcare provider about the medications that you are taking.
