Blood is extremely important for the normal functioning of the body, supplying cells with oxygen and nutrients, ensuring the exchange of information between tissues, organs, realizing endocrine regulation. It circulates in a confined space – the vascular bed, and its movement is supported by the work of the “pump” – the heart and the tone of the smooth muscles of the walls of arteries and veins.
Medicines included in this group are intended to preserve the rheological properties of blood – its fluidity, to replenish the volume of fluid circulating through the vessels, to form a thrombus and preserve the integrity (closure) of the vascular bed in cases where it is violated for any reason, for example, in case of injury; a separate subgroup unites substances that activate the formation of blood cells involved in the implementation of its many functions.
