What is Heartburn:
Heartburn is a painful burning feeling in your chest or throat. It happens when stomach acid backs up into your oesophagus, the tube that carries food from your mouth to your stomach. Pregnancy, certain foods, alcohol, and some medications can bring on heartburn. Treating heartburn is important because over time reflux can damage the oesophagus.
Many over-the-counter medications can help relieve heartburn. The options include: Antacids, which help neutralise stomach acid. Antacids may provide quick relief. But they can't heal an oesophagus damaged by stomach acid; H-2-receptor antagonists (H2RAs), which can reduce stomach acid. H2RAs don't act as quickly as antacids, but may provide longer relief; Proton pump inhibitors, such as lansoprazole (Prevacid 24HR) and omeprazole (Nexium 24HR, Prilosec OTC), which also can reduce stomach acid.
