All the metabolic and physiological processes in the human body can not take place continuously on one, and so onth same level without "outside help". As the "helper" or controls all these processes are the hormones - the active compounds are synthesized in the body of the glands of the endocrine system. One of the most important endocrine glands in humans are adrenals - two glands, each of which is located at its pole of the kidney.In the function of the adrenal glands include the regulation of metabolism, as well as the production of hormones that smooth stress response. Each of the three structural parts of the adrenal gland synthesizes a type of hormone that is responsible for: the metabolic processes in the kidney (corticosterone), metabolic processes in the body (cortisone), the development of secondary sex nSigns of (androgen), adaptation to stress (adrenaline). All these hormones are not produced in a free manner and are strictly controlled by another hormone - corticotropin. But our body can not iron and objectively exist diseases that affect the nervous and endocrine systems, glands and disrupting production in the required quantityhormones (both active and controlling). In such cases one used as a substitute or a stimulant drug, which has a common structure with the natural hormone, and thus, enhances its function. In the case of corticotropin such drug is a synthetic analogue of it - or tetrakozaktid. He artificially stimulatesyrabotku corticoids and is particularly effective in the treatment of diseases such as multiple sclerosis, rheumatism, eczema, psoriasis, colitis, cancer. It should be borne in mind that sinakten categorically contraindicated for use in the treatment of diseases, which may be accompanied by increased production of these hormones or defeat structure deses. This, for example, heart failure, allergies, infections, pregnancy, asthma.
