请问GAVISCON对这种病适用吗?可以长期服用吗?谢谢。
这个应该是OTC药来的,盒子上都没写是什么成分,查了下wiki才知道是什么。
胃粘膜保护剂,可以吃,效果没有PPI好。如果症状明显或者症状持续,还是要去看医生,避免长期服用掩盖病情。
Gaviscon is a non-prescription medicine, which is taken by mouth to treat heartburn and gastroesophageal reflux disease (GERD).[1] Like antacids in general, Gaviscon is available as a solid, syrup or tablet. It is produced and distributed in the UK, Ireland, Australia and Malaysia by Reckitt Benckiser,[2] in the US by GlaxoSmithKline and in Canada by Prestige Brands.[3]
The formulation of Gaviscon varies by manufacturer. The three active ingredients in Reckitt Benckiser's version are sodium alginate, a bicarbonate (either sodium or potassium in variants) and an antacid (calcium carbonate).[4][5] The GlaxoSmithKline variant lists only antacids as its active ingredients (aluminum hydroxide and either magnesium carbonate or magnesium trisilicate). Alginic acid and sodium bicarbonate are listed as inactive ingredients.[6][7]
The combination of alginic acid and a bicarbonate forms a layer on the contents of the stomach, which prevents stomach acid from refluxing up into the esophagus.[8] If reflux does occur the protective barrier is the first to contact the esophageal mucosa, instead of gastric contents.[9]
Gaviscon infant, for children of 1 year and older, contains only the gelling agents sodium alginate and magnesium alginate.[10] It helps stabilize the child's stomach contents to reduce reflux and regurgitation, but it is not an antacid.[11] |
