How does it work?
This medicine contains the active ingredient esomeprazole, which is a type of medicine called a proton pump inhibitor.
Proton pumps are found on cells that line the stomach and are used by these cells to produce stomach acid. Esomeprazole works by inhibiting the action of the proton pumps, and this reduces the production of stomach acid.
Acid is produced in the stomach as a normal part of the digestive process. However, in the condition known as gastro-oesophageal reflux disease or acid reflux, this acid is allowed to flow back into the food pipe (oesophagus), where it causes pain and a burning sensation known as heartburn. The acid can also irritate and cause inflammation of the lining of the foodpipe (reflux oesophagitis).
Esomeprazole reduces the production of stomach acid and thus reduces acid flowing back into the foodpipe. It is used to relieve the symptoms of gastro-oesophageal reflux disease, such as heartburn. It is also used to treat reflux oesophagitis, because stopping the acid flowing back into the foodpipe allows the lining of the foodpipe to heal. Esomeprazole is also used for the long-term management of people with healed oesophagitis, as suppressing the production of stomach acid helps prevent this condition recurring.
Esomeprazole is also used to treat ulcers in the stomach or upper intestine (peptic ulcers) that are associated with a type of bacteria called Helicobacter pylori. This type of bacteria is the most common cause of peptic ulcers. The bacteria cause the stomach to produce too much acid, which irritates the lining of the stomach and upper intestine and causes ulcers.
Esomeprazole is used in combination with antibiotics to eradicate Helicobacter pylori from the gut. The esomeprazole creates an environment in the gut in which the antibiotics can work effectively against the H pylori bacteria. The reduced acid in the gut allows the ulcer to heal, and both actions help prevent the ulcer from recurring.
Esomeprazole can also be used to prevent and treat peptic ulcers that can occur as a side effect of non-steroidal anti-inflammatory drugs (NSAIDs), such as diclofenac, often used to treat arthritis.
What is it used for?
- Eradicating Helicobacter pylori bacteria from the gut (in combination with antibiotics), which helps peptic ulcers to heal and prevents them from recurring
- Treatment and prevention of peptic ulcers associated with non-steroidal anti-inflammatory drugs (NSAIDs)
- Gastro-oesophageal reflux disease
Warning!
- This medicine can relieve the symptoms of stomach cancer and therefore delay diagnosis of this condition. For this reason, if your doctor suspects you have a stomach ulcer he should exclude the possibility of stomach cancer before you start treatment with this medicine, particularly if you are middle aged or older and have new or recently changed symptoms.
- Swallow the tablets whole, do not chew or crush them. If you have difficulty swallowing the tablets whole they can be dispersed in a glass of still water. Stir until the tablets disintegrate. The mixture will not be clear, as it will contain solid granules from the tablet. These should not be crushed or chewed, as they contain the medicine and are covered with a special coating. Drink the mixture immediately or at least within 30 minutes (stir again before drinking). To ensure you have taken all the medicine rinse the glass with water and drink. Do not use any other liquid to disperse the tablets, as this may affect the medicine.
