Losec is the branded version of Omeprazole. This particular brand comes in both the full strength and half strength of Omeprazole. It is a medicine that belongs to the family of drugs known as proton pump inhibitors (PPI). It is used to treat conditions such as acid reflux, gastro-oesophageal reflux disease (GORD) and heartburn. It works by preventing certain cells within the stomach lining from producing acid. This leads to a decrease in acid refluxing up towards the respiratory tract and causing symptoms associated with all the conditions above. It is recommended that the patient take a daily dose regularly for therapeutic results to be at its most effective.
