The first one is that when we use gastric mucosal protector, it is better not to use it with milk. Because the drug contains heavy metal ions, such as magnesium and aluminum ions and bismuth ions, these metal ions will be complexed with the amino acids in milk, which will reduce the effectiveness of the drug. Then there is our usual posture after taking the medicine is also very important. If you stand for a long time after taking the medicine, the time of contact between the medicine and the ulcer surface is relatively short, and the effect of the medicine cannot be given full play. It is recommended to lie down for a few minutes after taking the medicine, which can slow down the speed of drug evacuation and extend the time of drug action in the local area. There is also a gastric ulcer patients after taking gastric mucosal protective agents and other gastric drugs, do not drink a lot of water to do so, because if we drink a lot of water will make the gastric mucosa surface attached to the particles are diluted, the barrier effect of the drug is destroyed, but also make the drug weakened.
