Aminopeptidin is mainly a drug to increase blood cells. It is mainly characterized by increasing platelets. For example, patients in the hematology department have aplastic anemia, acute leukemia, myelodysplastic syndrome, MDS Lymphoma and chronic leukemia may lead to the reduction of blood cells in one or more lines, especially in the case of thrombocytopenia. Aminopeptide can stimulate bone marrow hematopoiesis, thus increasing blood cells. The best thing is to raise platelets to (100-300) × 10 ^ 9/L. The oral dose of aminopeptide is generally 4-5 capsules, 3 times/day, and the basic course of treatment is 10-15 days.
