Flexibility to take with or without food

VOQUEZNA (vonoprazan) is a class of medication called a potassium-competitive acid blocker (PCAB) that works differently than other prescription and over-the-counter medications, like antacids, histamine blockers, and proton pump inhibitors (PPIs). Unlike most PPIs, VOQUEZNA can be taken with or without food.

How does VOQUEZNA work?

After taking VOQUEZNA, the medication travels to the stomach where it binds to the proton pump.

Here, VOQUEZNA blocks potassium from binding to the pump. This stops the proton pump from working.

When the proton pump can‘t work, it can no longer produce acid. VOQUEZNA can help suppress acid for 24 hours.

In a study of healthy people, VOQUEZNA has been shown to reduce acid within 2-3 hours and maintain acid suppression over 24 hours.
