Adrenochrome tablets are oxidized derivatives of adrenal glands, but have no adrenomimetic effect, so they do not affect blood pressure and heart rate, and can enhance capillary resistance to damage, so they can stabilize acidic mucopolysaccharides in blood vessels and their surrounding tissues, reduce capillary permeability, and enhance the retraction of damaged capillaries, so that clots are less likely to be dislodged from the walls of the tubes, which in turn shortens the hemostatic time. However, it does not affect the clotting process itself, so it is often used to treat bleeding caused by capillary damage and increased permeability, such as epistaxis, retinal hemorrhage, hemoptysis, gastrointestinal hemorrhage, hematuria, hemorrhoids and uterine hemorrhage, and can also be used for thrombocytopenic purpura. However, there are some side effects, because the drug itself has a certain low toxicity effect, may produce a salicylic acid drug reaction, so nausea, vomiting, tinnitus, vision loss may occur. In patients with epilepsy it may cause abnormal brain electrical activity, while people who use it heavily may experience the side effect of mental disorders.
