The most common anemia in China is iron deficiency anemia. Because iron is an essential raw material to produce hemoglobin (hemoglobin), if iron supply is insufficient and hemoglobin is reduced, anemia will easily occur. For iron deficiency anemia, the commonly used blood-enriching drugs are as follows: iron agent is mainly used for the prevention and adjuvant treatment of iron deficiency anemia. At present, ferrous sulfate, ferrous fumarate, ferrous gluconate, iron dextran, ferrous succinate, polysaccharide iron complex and so on are the main ferrous agents sold in pharmacies, among which ferrous sulfate belongs to inorganic iron and others are organic iron. In addition, there are many traditional Chinese medicine preparations for iron supplementation, such as Xuebao Capsule, Xuebao Oral Liquid, Wei Xue Granule and Kang Xue Granule. Inorganic iron is cheap and good, and its biggest disadvantage is obvious gastrointestinal adverse reactions. Organic iron, such as oral iron dextran, ferrous succinate, polysaccharide iron complex, etc. High iron content. Compared with ferrous sulfate, the adverse reaction is mild and the curative effect is equivalent, but the price is higher. It is best to use various iron-supplementing and blood-enriching drugs under the guidance of doctors according to everyone's situation. When taking "blood tonic", some foods will also affect the absorption of iron, such as tea, coffee, eggs, milk and foods containing more dietary fiber. 1 ferrous sulfate tablets are ferrous iron, which is easy to absorb and has obvious curative effect. If taken together with pepsin mixture and vitamin C, it will promote its absorption. When used with tetracyclines, they can form complexes and interfere with each other's absorption. Generally taken after meals, it can reduce the irritation to the gastrointestinal tract, but it can still cause stomach discomfort, nausea, vomiting, diarrhea and other reactions, and occasionally lead to constipation. After taking the medicine, the stool is grayish black because some iron is discharged from the stool. During taking, it is not advisable to drink tea, coffee or eat food such as olives, because the tannic acid contained in it will combine with iron to produce precipitation, which will affect the curative effect. Ferrous fumarate tablets (blood-rich iron tablets) are easy to be absorbed after oral administration, with high iron content, quick response and few side effects. Can be used for treating various iron deficiency anemia. However, those who are allergic to iron, or those with digestive tract ulcer, ulcerative colitis and enteritis are prohibited. Other matters needing attention are the same as ferrous sulfate tablets. Because ammonium ferric citrate solution is trivalent iron, it is not as easy to be absorbed as ferrous sulfate tablets and blood-rich iron tablets, but it is not irritating. Suitable for children and patients who can't swallow tablets. Because of its low iron content, it is not suitable for patients with severe anemia. This medicine is easy to deteriorate when exposed to light, so it should be stored in a cool and dark place. Rinse your mouth or suck with a glass tube after taking it to protect your teeth. Use with caution in patients with diarrhea. Vitamin drugs, including vitamin b 12 and folic acid, have special effects on megaloblastic anemia caused by folic acid deficiency and vitamin b 12, but have no effect on other anemia. High-dose vitamin b6 is effective in the treatment of primary or hereditary sideroblastic anemia, but not for other anemia. It can be seen that the mechanism of various vitamin drugs in treating anemia is different and cannot be used blindly. Folic acid tablet 1 participates in the synthesis of amino acids and nucleic acids in human body, and promotes the formation and maturation of red blood cells together with vitamin B12 * * *, so it is used for various megaloblastic anemia. It is especially suitable for pregnancy and megaloblastic anemia in infants. When used in pernicious anemia, it should be combined with vitamin b 12 to prevent and treat its nervous system symptoms. Vitamin b 12 injection has certain effects on bone marrow hematopoietic function and liver function. Mainly used for various megaloblastic anemia or pernicious anemia, with good curative effect. This drug may cause allergic reaction, even anaphylactic shock, and should not be abused. 3 coenzyme vitamin b 12 tablet is a new type of vitamin b 12. Mainly used for megaloblastic anemia and dystrophic anemia. It needs to be stored in a dark place. Ganjing tablet contains vitamin b 12, folic acid and other ingredients, and is used for pernicious anemia. But the effect is weak. Adrenal glucocorticoid drugs such as prednisone and dexamethasone. Because these drugs have immunosuppressive effect, they have good curative effect on autoimmune hemolytic anemia. It also has certain curative effect on paroxysmal nocturnal hemoglobinuria and spherocytosis. However, such drugs can only be used on the premise of confirmed illness. Androgen drugs such as testosterone propionate, stanzole, danazol, etc. These drugs are necessary for the treatment of aplastic anemia, and also have a good effect on anemia related to myeloma and myelodysplastic syndrome. Its pharmacological action is mainly to stimulate the proliferation of erythroid hematopoietic cells, and its main side effects are acne-prone, masculine performance and liver injury. In addition, erythropoietin is a biological regulator produced by high technology in recent years, and it is also the most effective drug for treating renal anemia at present. It can also be used to treat anemia caused by aplastic anemia, leukemia and other tumors. It can effectively stimulate the proliferation and differentiation of patients' red blood cells and promote the synthesis of hemoglobin. The main side effect of this drug can increase blood pressure, so cobalt chloride solution should be used together with antihypertensive drugs to stimulate bone marrow and promote erythropoiesis, which is mainly used for aplastic anemia and renal anemia. Take it after meals. There may be side effects such as anorexia, nausea and abdominal pain. It should be noted that anemia patients not only need medication, but also pay attention to daily diet and increase nutrition. People without anemia don't need to take blood-enriching drugs. In a word, anemia is a disease with complex etiology, and different types of blood-enriching drugs have different pharmacological effects. Patients should choose blood-enriching drugs under the guidance of experts.
