Antianemic drugs, such as certain vitamins or iron, enhance the formation of red blood cells. Anticoagulants like heparin reduce blood-clot formation and ensure free blood flow through major organs in the body. Thrombolytic drugs dissolve blood clots, which can block blood vessels and deprive the heart or brain of blood and oxygen, possibly leading to heart attack or stroke.

 The antianemic action of ampevit and orkomin developed at the Laboratory of Experimental Therapy, Institute of Gerontology, Academy of Medical Sciences of the USSR was studied in experiments on young and old animals. It has been established that repeated administration of the drugs increases the reticulocyte count in both groups of animals. Ampevit diminishes severity of posthemorrhagic anemia. Both drugs promote more rapid recovery of hemoglobin content and red cell count in old animals after blood loss. The data obtained were supported by clinical trials of the drugs which have been recommended for combined treatment of posthemorrhagic anemias and other conditions accompanied by weakened function of the growing red fiber of the bone marrow seen also in people of old and senile age.
