Benefits of Protera-L Capsule SR

Treatment of Gastroesophageal reflux disease (Acid reflux)
Gastroesophageal reflux disease (GERD) is a chronic (long-term) condition which is like having heartburn consistently rather than just occasionally. It happens because a muscle above your stomach relaxes too much and allows stomach contents to come back up into your oesophagus and mouth. Protera-L Capsule SR reduces the amount of acid your stomach makes and relieves the pain associated with heartburn and acid reflux. You should take it exactly as it is prescribed for it to be effective.

Some simple lifestyle changes can help reduce the symptoms of GERD. Think about what foods trigger heartburn and try to avoid them; eat smaller, more frequent meals; try to lose weight if you are overweight and try to find ways to relax. Do not eat within 3-4 hours of going to bed.

Side effects of Protera-L Capsule SR

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

How Protera-L Capsule SR works

Levosulpiride is a prokinetic that works by increasing the release of acetylcholine (a chemical messenger). This increases the movement of the stomach and intestines and prevents reflux (acid going up to the food pipe). Pantoprazole is a proton pump inhibitor (PPI). It works by reducing the amount of acid in the stomach, which helps in the relief of acid-related indigestion and ulcers.
