Although there are many kinds of stomach medicine, but the time to take the medicine is basically focused on 3 points in time. One, half an hour before meals This point in time is suitable for taking drugs that protect the gastric mucosa and promote gastric power. The former, such as aluminum thioglycollate (gastric ulcer), bismuth potassium citrate (Lizudra), they need to form a protective film directly on the surface of the stomach wall, so as to play a barrier role, so usually need to be taken half an hour to an hour before meals, in order to avoid food impede the contact between the drug and the stomach wall. The latter, such as domperidone (morpholine), as well as cisapride and mosapride, are best taken 15 to 30 minutes before a meal. This allows some time for the drug to be absorbed and work, giving full effect and promoting gastrointestinal peristalsis. It is important to note that gastric motivation drugs should not be taken at the same time as antacids. In addition, many people now take some gastric mucosa protection drugs before drinking to avoid alcohol damage to the stomach. This practice can indeed play a certain protective effect on the stomach, but can not offset the damage caused by alcohol to the liver and other organs. Second, follow the meal point to eat after the meal stomach acid secretion will greatly increase, so the best acid suppressants follow the meal point to take. Such as cimetidine, ranitidine and other histamine receptor antagonists, it is best to take immediately after meals; and omeprazole (Loxacol), lansoprazole and other proton pump inhibitors, it is best to take before meals on an empty stomach. Be aware that such drugs should be swallowed whole. In addition, when acid-suppressing drugs are combined with antacids, the time between doses should be no less than 1 hour. Third, one hour after meals mainly refers to neutralize stomach acid drugs, including sodium bicarbonate, aluminum hydroxide (gastric relief), aluminum magnesium carbonate (Daxi), etc.. They can quickly neutralize stomach acid and relieve stomach discomfort. Therefore, when taken 1~1.5 hours after a meal, when gastric acid secretion reaches its peak, the maximum neutralizing ability of the drug can be brought into play and its effect can be maintained for 3~4 hours. However, if taken immediately after a meal, the effect of the drug can only be maintained for about 1 hour. In addition, stomach acid will continue to secrete, if the effect of taking medicine is not obvious, you can take an additional dose of medicine, but do not increase the dose of each dose, such as one hour and three hours after a meal, and then an additional dose before bedtime.
