The use of adrenal hormones needs to be strictly prescribed by a doctor who assesses whether there is an indication for them and instructs them on their specific usage. Adrenal hormones can be categorized into adrenocorticotropic hormones and adrenomedullary hormones. Adrenocorticotropic hormones mainly include cortisol and aldosterone. Adrenomedullary hormones mainly include epinephrine and norepinephrine, etc. The main role of adrenocorticotropic hormone is to regulate water and salt metabolism and sugar metabolism, which is mainly applied to infectious diseases, shock, adrenocortical insufficiency and other diseases. However, it is easy to induce fetal malformation and aggravate the possibility of infection, so it is not suitable for newborns, pregnant women and lactating people, as well as severe diabetes and other chronic diseases. While adrenaline in adrenal medullary hormones can enhance the contractility and excitability of the heart muscle and make the blood vessels of the heart and skeletal muscle dilate. Norepinephrine, on the other hand, exerts a strong contractile effect on blood vessels throughout the body, except for the coronary arteries, and can increase peripheral resistance. It is therefore indicated in emergency situations such as anaphylactic shock resuscitation. In summary, adrenal hormones must be used as prescribed by a doctor, and need to be directed by a doctor according to the specific condition.
