What is the difference between Prevacid®24HR and H2 blockers (like Pepcid®** and/or Zantac®***)?
Prevacid®24HR is a newer class of drug called a Proton Pump Inhibitor (PPI). Prevacid®24HR works by stopping the release of acid into the stomach from specialized cells called “proton pumps.” Prevacid®24HR prevents the acid that causes heartburn at the source. H2 is the abbreviation for a class of drugs called histamine (2) receptor antagonists. H2 blockers work by decreasing the amount of acid produced by the stomach.
