Definitions
- the present invention relates to the field of erythropoiesis.
- the present invention relates to the use of substituted 5-methyldihydropyridazinones for the production of medicaments for the prophylaxis and / or treatment of anemias.
- new substituted 5-methyldihydropyridazinones and their preparation are described.
- Anemia also known as anemia, is characterized by a decrease in the number of erythrocytes, hemoglobin concentration and / or hematocrit below the age-appropriate and gender-specific reference values.
- the anemia is characterized by the reduced oxygen transport capacity of the blood, inter alia by the disturbance of oxygen-dependent metabolic and organ functions; with acute development (e.g. due to blood loss), symptoms of shock may appear, and with chronic development there is often a slowly progressive course with decreased performance, fatigue, dyspnoea and tachycardia.
- anemia can be classified or classified according to the morphology and hemoglobin content of the erythrocytes or according to the etiology (eg post-hemorrhagic anemia, gestational anemia, tumor anemia, infectious anemia or deficiency anemia). It is also possible to classify the various forms of anemia according to their pathogenesis, taking into account the possible causes, for example in anemia caused by over moderate blood loss (e.g. acute or chronic bleeding anemia), anemia due to reduced or ineffective erythropoiesis (e.g.
- iron deficiency anemia iron deficiency anemia, nephrogenic anemia or myelopathic anemia
- anemia due to excessive erythrocyte breakdown so-called hemolytic anemia
- iron preparations are generally used, which are administered either orally or parenterally.
- gastrointestinal disorders are observed as a side effect.
- parenteral iron therapy which also proves to be difficult due to the low iron binding capacity of the plasma, it can lead to nausea, vomiting, heart and headache, heat sensation as well as a sharp drop in blood pressure with collapse, in addition to the deposition of iron in the overdose Reticuloendothelium (hemosiderosis) come; the walls of the vessels are damaged by the intravenous injection; thrombophlebitis and thrombosis must also be expected.
- Dosage proves to be extremely difficult because all iron that cannot be bound physiologically with parenteral administration has a toxic effect (Gustav Kuschinsky, Heinz Lüllmann and
- RhEPO Genetically engineered recombinant erythropoietin
- EPO Erythropoietin
- rh EPO is administered. These include the development and exacerbation of high blood pressure and the cause of symptoms similar to encephalopathy, to tonic-clonic convulsions and cerebral or myocardial infarction due to thrombosis. Furthermore, rh EPO is not available orally and must therefore be administered intraperitoneally (i.p.), intravenously (i.v.) or sub-cutan (s.c.), making it harder to apply to therapy
