Iron deficiency anemia – new possibilities of iron supplementation in various clinical conditions

Iron deficiency anemia – new possibilities of iron supplementation in various clinical conditions AbstractIron deficiency anemia (IDA) treatment is done to eliminate the causes of iron deficiency, iron supplementation, and rarely red blood cell transfusion. Divalent iron salts are the first line of oral treatment, but their use lead to frequent gastrointestinal adverse reactions. Iron is administered intravenously in the event of contraindications, intolerance, or inefficiency of oral therapy, but the parenteral route of drug delivery is not easily accepted by the patients. Intravenous preparations for single administration of a large dose of iron have a good therapy safety profile, but are more expensive than oral and are usually administered in a hospital setting. The availability of new iron compounds: sucrosomial iron, ferric citrate complexes, and ferric maltol widen the possibilities of IDA therapy and enable the better selection of iron preparations in various clinical situations. The innovative structure of sucrosomial iron leads to absorption in different ways (through endocytosis, the paracellular pathway, M cells of Peyer's patches), ensures high bioavailability, and good tolerance of therapy.

Abstract

AbstractIron deficiency anemia (IDA) treatment is done to eliminate the causes of iron deficiency, iron supplementation, and rarely red blood cell transfusion. Divalent iron salts are the first line of oral treatment, but their use lead to frequent gastrointestinal adverse reactions. Iron is administered intravenously in the event of contraindications, intolerance, or inefficiency of oral therapy, but the parenteral route of drug delivery is not easily accepted by the patients. Intravenous preparations for single administration of a large dose of iron have a good therapy safety profile, but are more expensive than oral and are usually administered in a hospital setting. The availability of new iron compounds: sucrosomial iron, ferric citrate complexes, and ferric maltol widen the possibilities of IDA therapy and enable the better selection of iron preparations in various clinical situations. The innovative structure of sucrosomial iron leads to absorption in different ways (through endocytosis, the paracellular pathway, M cells of Peyer's patches), ensures high bioavailability, and good tolerance of therapy. Ferric citrate, in addition to iron supplementation, reduces phosphate levels, and is beneficial to chronic kidney disease. Ferric maltol is currently being studied for IDA treatment with various comorbidities. Some studies indicate that new iron formulas may be used where intravenous intake has been recommended so far. So, we can expect treatment with iron nanoparticles and drugs that affect the intestinal microflora in the future. The paper presents current knowledge about new iron preparations that are already available in everyday practice, but also those that are at various stages of pre-clinical and clinical studies.
