What Omeprazole AN is used for
Omeprazole AN is used to treat peptic ulcers. Depending on the position of the ulcer it is called a gastric or duodenal ulcer.
A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out from the stomach.
These ulcers can be caused by too much acid being made in the stomach.
Omeprazole AN is also used to help stop peptic or duodenal ulcers coming back.
Peptic Ulcers Associated with Helicobacter pylori Infection
Most peptic ulcers are caused by an infection with the bacterium Helicobacter pylori in the stomach.
H. pylorus weakens the protective mucous coating of the stomach and duodenum, which allows acid to get through to the sensitive lining beneath. Both the acid and the bacteria irritate the lining and cause a sore, or ulcer.
When Omeprazole AN is taken together with an antibiotic, the combination will kill H. pylori and let your peptic ulcer heal.
Peptic Ulcers Associated with Non-Steroidal Anti-Inflammatory Drugs (NSAID’s)
Some peptic ulcers are caused by medicines called non-steroidal anti-inflammatory drugs. These medicines are commonly taken to treat joint disease or arthritis.
Omeprazole AN is also used to heal and prevent ulcers associated with NSAIDs.
Omeprazole AN is used to treat the symptoms of reflux oesophagitis or reflux disease. This can be caused by "washing back" (reflux) of food and acid from the stomach into the food pipe (oesophagus).
Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.
Omeprazole AN is also used to help stop reflux oesophagitis coming back or relapsing.
Omeprazole AN is also used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces large amounts of acid, much more than in ulcers or reflux disease.
Your doctor will have explained why you are being treated with Omeprazole AN and advised you what dose to take. Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
Your doctor may prescribe this medicine for another purpose. Ask your doctor if you have any questions about why Omeprazole AN has been prescribed for you.
This medicine is available only with a doctor’s prescription.
There is no evidence that Omeprazole AN is addictive.
How does Omeprazole AN work?
Omeprazole AN is a type of medicine called a proton pump inhibitor. Your stomach produces acid to help break down food so it is easier to digest. In certain circumstances, this acid can irritate the lining of your stomach and duodenum (the tube leading out from the stomach) causing indigestion and even ulceration and bleeding.
The proton pump inhibitors work by decreasing the production of stomach acid, to give relief of symptoms and allow healing to take place. They do this by inhibiting a system in the stomach known as the proton pump. This does not stop food being digested in the normal way.
