What is the Difference Between Omeprazole and Lansoprazole?
If you suffer from acid reflux and heartburn you’ve probably heard of omeprazole and lansoprazole.
But how do they differ and what exactly do they do? In this blog, we’ll examine the difference between Lansoprazole vs Omeprazole, how they differ and what they do.
We’re here to provide you with the lowdown on both of these medicines including their uses and how they work.
What are Lansoprazole and Omeprazole?
Omeprazole and lansoprazole are both classed as a proton pump inhibitor (PPI).1
You may be more familiar with omeprazole as it’s more commonly prescribed as a gastrointestinal medication than lansoprazole.2
Both reduce the amount of acid the stomach makes.3/4
What are omeprazole and lansoprazole used to treat?
Omeprazole and lansoprazole are used for the short-term treatment of acid reflux, heartburn, indigestion and symptoms of gastro-oesophageal reflux disease (GORD). 3/4 If you think you may be suffering from GORD, seek the advice of a GP for a diagnosis.
How does a proton pump inhibiter work?
Proton pumps are enzymes in the lining of the stomach.4
They help the stomach to make the acid needed to digest food but for some people, it can irritate the stomach and cause discomfort. Acid reflux is caused by acid travelling up into the oesophagus which causes the pain of heartburn.5
PPIs work by reducing the amount of acid the stomach makes by preventing the proton pumps from working properly.4
This reduces the pain and discomfort in the stomach or the chest caused by acid reflux.
