Usually abdominal pain can be reduced after 1-2 hours of taking Daxi. Daxi, also known as magnesium aluminum carbonate tablets, mainly has the effect of protecting the gastric mucosa and inhibiting gastric acid, mainly used for excessive secretion of gastric acid, bile reflux and peptic ulcer caused by heartburn, acid reflux, epigastric pain, etc.. After entering the stomach orally, Daxil can be rapidly decomposed and melted to form a protective film in the inner wall of the stomach, which can protect the gastric mucosa. In addition, Daxil is alkaline and can combine with gastric acid and bile to neutralize gastric acid and inhibit the effect of gastric acid. The process of decomposition and utilization of Daxil takes about 1 hour, but the time of its onset of action varies depending on the body type of the person and the environment in the stomach. In addition, due to the high content of magnesium and aluminum in Daxil, it should not be taken by people with chronic kidney disease. If a patient has acute abdominal pain, it is recommended to go to the hospital promptly for a clear diagnosis before taking the drug to avoid delaying the condition.
