Iron preparations for anemia: a review of the means

Iron preparations for anemia: a review of the means

Iron is one of the indispensable elements that ensure the stable functioning of the body.Basically, this microelement enters the body together with food - there are a number of products in which the level of iron content is very high.But in some cases, even the active use of such peculiar foods does not help to keep the balance of iron in the body - in this case, doctors diagnose anemia of iron deficiency and prescribe therapy with specific medications.

Basic information about iron preparations

6d7de312fc99ce2f80950fcdec37f244

In the dosage form, the useful micronutrient in question can be contained in two different forms:

  • is a divalent form - iron preparations are absorbed quickly and fully, applied orally( ingestion by ingestion);
  • trivalent form - drugs are digested worse, injected.

A medicinal preparation with iron content is absorbed in the digestive tract, but for this process it is necessary to have a sufficient amount of hydrochloric acid in the stomach.Therefore, if the patient is prescribed iron therapy, but he was previously diagnosed with a deficiency in hydrochloric acid production, the patient must necessarily take in parallel the medicines that increase the acidity of the gastric juice.

There is a definite differentiation of substances that increase or decrease the absorption of iron preparations:

  • fructose, succinic acid, cysteine ​​and ascorbic acid - increase;
  • tannin, phosphoric acid, tetracycline, almagel - lower.

Naturally, the latter substances with the use of drugs with iron content should be excluded.

Iron preparations for ingestion

Recommended to read:

Usually, when diagnosing iron deficiency anemia, doctors prescribe medications for ingestion.Dosage is established strictly on an individual basis, but there are general recommendations - adults usually need to take 2 mg per kilogram of weight and, as a rule, a day it is 100-200 mg of the drug, extremely rarely 300 mg.

If the dose of iron-containing drug was correctly selected, after a few days of therapy the patient begins to feel better, the standard symptoms of iron deficiency anemia practically disappear.In the first 5-7 days of the use of drugs with iron content, the first positive changes in the results of laboratory blood tests appear - the number of reticulocytes begins to grow.And after 60-90 days of regular intake of iron-containing drugs, stable growth of hemoglobin is observed.

Note: patients need to take iron preparations inside for a long time to restore their health.Even if the hemoglobin and general health status have already stabilized, it is impossible to stop therapy - it is necessary to create a micronutrient reserve in the body.But at the time of "storage" of iron in the body do not need to take the prescribed daily dose of medications - the doctor, based on the results of laboratory blood tests, usually adjusts the dosage to reduce it by 2 times.

Taking iron preparations orally( orally) may be accompanied by the development of side effects:

  • nausea and vomiting that appear regardless of eating;
  • decreased appetite, and in some cases, a complete aversion to food;
  • strongly pronounced metallic taste in the mouth;
  • disruption of the bowels - constipation or diarrhea.

Often, against the background of the use of iron-containing drugs orally( inside), there may appear a gray coating on the tooth enamel, so doctors recommend either rinsing the mouth immediately after using the medication, or drinking it through the tube if the drug is in liquid form.
