Omeprazole is a treatment used for heartburn, and is made in tablet-form by Dexcel, and in capsule-form by Mylan. It is a generic alternative to Losec, which is the name of the branded version. Its capacity to reduce the presence of stomach acid means that it can also be used to relieve other symptoms which can occur as a result of gastroesophageal reflux, or GORD. These include the unpleasant taste in the mouth caused by acid reflux, as well as pain and difficulty with swallowing.

  1. Easy to use capsule
  2. Sold in a range of doses
  3. Proficient at reducing heartburn

The name heartburn is quite misleading, as it is a condition which does not affect the heart. It takes hold when acid from the stomach creeps up into the passage connecting it to the mouth and throat, also known as the oesophagus. This substance is abrasive to the tissues in these areas, and as a result, pain and a sensation of burning may become present.

Many people at some point in their lives will get heartburn, but the majority may only experience infrequent instances of it. In cases where the problem persists, however, a doctor may advise taking measures to treat it. There are several possible causes. It may present itself after the consumption of a large meal, or excessive amounts of alcohol. Those who are overweight or have a high fat diet are thought to be more at risk, as are those are pregnant.

It occurs in the body when the function of the oesophageal sphincter becomes compromised. This is a small group of muscles, situated at the base of the oesophagus, which help to control the flow of food into the stomach. In simple terms, these muscles function as a gateway; opening to allow food into the stomach; and closing up again afterwards to prevent stomach acids from getting out.

When extra pressure is exerted on these muscles, due to the stomach being full, or the presence of high body mass, they can start to not function as well. This means that they cannot close as easily, and acid escapes upwards into the upper digestive tract., causing burning feelings of pain.

The active ingredient in Omeprazole works on proton pumps in the wall of the stomach. These are responsible for the production and release of acids, which are essential in the breaking down of food. By stifling the action of these pumps, Omeprazole lowers the amount of stomach acids they produce, and helps to decrease symptoms.

Omeprazole can also be employed to medicate ulcers in the stomach and intestinal tract, and those caused by bacterial infections when used in unison with antibiotics.
