Multi-Enzyme Tablets have the effect of aiding digestion and belong to a symptomatic treatment drug, which has little therapeutic effect on chronic gastritis itself, and has some therapeutic effect on symptoms such as gastric distension, nausea, vomiting and loss of appetite caused by chronic gastritis. For patients with chronic gastritis, they need to be treated with drugs that inhibit gastric acid secretion and protect the gastric mucosa, such as omeprazole, pantoprazole, rabeprazole, aluminum magnesium plus suspension, and aluminum thioglycollate. In the case of chronic gastritis caused by H. pylori infection, treatment with anti-H. pylori quadruple therapy, i.e. 1 proton pump inhibitor + 2 antibiotics + 1 bismuth agent to kill H. pylori, is required to achieve therapeutic effect. In the process of taking Multi-Enzyme Tablets, patients should pay attention to abstain from alcohol, avoid the stimulation of spicy, cold and greasy food, and children, pregnant and lactating women, and the elderly should use the drug under the guidance of a doctor. The drug is easily destroyed under acidic conditions, so do not chew it when taking it. Aluminum preparations may affect the efficacy of the drug, so it is not suitable to be used in combination with aluminum preparations, and if used simultaneously with other drugs, drug interactions may occur.
