Losec MUPS 20mg tablets are an effective treatment for acid reflux symptoms. Losec MUPS is taken as an oral tablet and reduces the amount of acid in the stomach. This prevents gastric acid from refluxing up into the oesophagus, helping to relieve symptoms such as heartburn and acid reflux. This proton pump inhibitor is most effective when taken once daily, usually at the same time each day.

Losec MUPS is a commonly prescribed medication for acid reflux. The medication works by reducing the amount of stomach acid produced by the body, helping prevent acid from refluxing back into the oesophagus. Losec tablets are also used to treat gastro-oesophageal reflux disease (GORD).

Losec MUPS contains the active ingredient Omeprazole, which is part of a group of medicines known as proton pump inhibitors (PPI). Losec MUPs work by blocking enzymes called ‘proton pumps’ responsible for creating stomach acid.
