Because a certain concentration of gastric acid is necessary for food to be digested in the stomach, patients with gastric disease take antacids to neutralize excessive gastric acid, so it is advisable to wait for the gastric contents to be nearly emptied before giving full play to the antacid effect of the drug, so it is best to take it 1 hour after meals and before bedtime.
