Zanprol tablets contain the active ingredient omeprazole, which is a type of medicine called a proton pump inhibitor. (NB. Omeprazole is also available without a brand name, ie as the generic medicine.) Omeprazole acts in the stomach to decrease the production of stomach acid.Proton pumps are found on cells that line the stomach and are used by these cells to produce stomach acid. Omeprazole 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, sometimes this acid can flow back into the food pipe (oesophagus). This is called gastro-oesophageal reflux, and can cause pain and a burning sensation known as heartburn. Omeprazole reduces the production of stomach acid and therefore stops excess acid flowing back into the foodpipe. It can therefore be used to relieve heartburn symptoms associated with acid reflux. The initial dose is two tablets swallowed whole with plenty of liquid, eg water or fruit juice, once a day before a meal. The medicine should start to provide relief of heartburn symptoms within a day or so of starting treatment, but it may take two to three days of treatment before the symptoms are fully relieved. Once your symptoms are relieved the dose should be reduced to one tablet once a day.If your heartburn is not relieved within two weeks of starting treatment with this medicine you should consult your doctor. If you need to keep taking this medicine continuously for more than four weeks to control your heartburn symptoms you should consult your doctor.
