• to treat a condition called reflux oesophagitis which causes heartburn
• to treat other problems such as indigestion or heartburn where a reduction in stomach acid is required
• to prevent ulcers in the small intestine which are sometimes caused as a side effect of taking nonsteroidal anti-inflammatory drugs (sometimes used to treat arthritis e.g. aspirin, ibuprofen, naproxen)
• to prevent bleeding of existing ulcers and gastrointestinal bleeding from stress ulceration in seriously ill patients
• before administration of a general anaesthetic to patients considered to be at risk of Mendelson’s syndrome (e.g. patients during labour), a condition where acid fluid from the stomach is brought up into the windpipe and passes into the lungs.
