Because milk contains more inorganic salts, such as calcium, phosphorus, iron, a variety of vitamins, proteins, amino acids and fats and other chemical substances, it is easy to chemically react with drugs, generating stable chromium compounds or insoluble salts, making it difficult to absorb drugs, and some drugs are even destroyed by these ions, reducing the concentration of drugs in the blood and affecting the efficacy of the treatment; at the same time, the absorption of milk by the human body is also affected, and And it increases the burden of the stomach. There are interactions between milk and many drugs, which can occur when taken at the same time, forming a thin film on the surface of the drug and the gastric mucosa, after the film is digested and absorbed, the drug has missed the best absorption period, thus reducing the absorption and efficacy of the drug. The calcium, phosphorus and iron in milk can easily react chemically with organic substances in traditional Chinese medicine to produce insoluble and stable compounds, which can damage the active ingredients of milk and medicine. It is better to take the medicine with water, not with milk or tea, etc. Babies should also take breast milk after taking the medicine for a period of time. Please be careful when taking the following drugs! 1, antibacterial drugs The metal ions in milk can combine with quinolones, tetracyclines, oxytetracycline, erythromycin, metronidazole and other antibiotics to form insoluble chelates, affecting absorption, reducing the antibacterial effect and making the drug less effective, or even completely ineffective. 2, calcium and aluminum preparations The proteins in milk can form coagulation with calcium lactate, calcium gluconate, aluminum hydroxide and other calcium and aluminum preparations, which not only affects the absorption, but also increases the burden on the stomach and intestines. 3, iron preparations Iron deficiency anemia is a common disease in women and children. Calcium ions in milk can compete with iron in the duodenal absorption site, reducing the efficacy, and milk cannot be taken at the same time when taking iron-containing drugs. 4, antacids bismuth potassium citrate, gastric, sodium bicarbonate and other antacids with milk can lead to lacto-alkaline syndrome. 5, cardiac drugs Milk and digitalis, digoxin cardiac drugs taken together, because the calcium contained in milk can enhance the toxicity of digitalis, digoxin, drugs are prone to accumulative toxic reactions, and even accidents. 6, anti-diarrheal drugs Milk can not be taken with anti-diarrheal drugs, because the milk contains lactose components, can reduce the effectiveness of anti-diarrheal drugs, but also aggravate the symptoms of diarrhea. The protein in milk can also form clots with calcium lactate, calcium gluconate, aluminum hydroxide and other calcium and aluminum preparations, increasing the burden on the stomach and intestines, and in serious cases, generating gallstones and kidney stones. 7, antihypertensive drugs Severe hypertension patients using antihypertensive drugs such as eugenol meet with milk or dairy products, may cause a sudden rise in blood pressure, and in severe cases, blood pressure will continue to rise, and even the occurrence of hypertensive crisis. 8, antidepressants Milk can not be taken at the same time with antidepressants monoamine oxidase inhibitors, because milk is rich in tyramine, when this enzyme is inhibited, tyramine will be a large accumulation, causing a sudden rise in blood pressure, heart rhythm disorders, serious cases can lead to brain hemorrhage or even death. The majority of herbal medicines and proprietary Chinese medicines cannot be taken with milk. In short, it is best not to take milk with drugs at the same time, taking drugs and drinking milk should be at least one hour apart, in order to avoid interactions, hard drug efficacy, increasing unnecessary side effects. The drugs that interact with milk 1, vitamin C Do not drink milk when taking vitamin C, not to mention the delivery of vitamin C with milk, because the vitamin B2 and vitamin C in milk will be in the gastrointestinal tract of the redox reaction and failure. 2. Levodopa This drug is absorbed in the small intestine and needs the help of a carrier when it runs in the body. Aromatic amino acids (such as phenylalanine) contained in milk proteins compete with levodopa for the same carrier system, thus affecting its absorption. Milk can cause premature dissolution of the drug’s intestinal coating and lead to gastric or duodenal irritation, therefore, milk should not be consumed within 2 hours before and after taking Bisacodyl tablets. 4.Mercaptoethylamine Milk food may reduce the absorption rate of this drug, blood concentration will be reduced and thus affect the efficacy, should be avoided in combination with milk. 5.Estramustine Eating dairy products or other calcium-containing foods while taking this drug may reduce the blood concentration of the drug. The drug instruction manual recommends that the drug can be taken with milk products to reduce the stimulation of the stomach: codeine, aminoglutethimide, azelastine, promethazine, chlorpheniramine, cyproheptadine, methoxsalen, phenothiazine, panflora, sulpiride, nicorantin, clindamycin, clarithromycin, piribedil, docusate sodium, phenytoin sodium, ethosuximide, quinidine, phenobenzyme, etc.
