The present Invention relates to a newly designed product, i.e. substance (B+C) that combines two different mechanisms of action that allow the control of aldosterone synthesis and secretion without compromising the metabolism of cortisol (corticosterone In rats) in the.tone glomerulosa of the adrenal gland. The innovative design of the described molecule enables ths individual use of substance (B+C) in the treatment of diseases such as hyper and hypo aldosteronism, Conn's syndrome and cytokine storm caused by Covid infection or as co-therapy with corticosteroids in the treatment of a whole range of immunological diseases. The innovative design of Substance (8+C) has an additional practical and economic advantage because the patient receives both components of substance (B+C) simultaneously with just one application, regardless of the medicine formulation. This not only simplifies the medicine synthesis, dosing and clinical research, but also the application of the medicine in clinical practice. For successful and selective control of aldosterone synthesis, which in nature also means selective control of blood pressure, it was necessary to combine the two substances described in order to ensure action in patients with elevated and / or towered blood pressure with one application of Substance (B+C). This feature of Substance (B+C) is important, especially in the treatment of patients with permanently impaired aldosterone synthesis, such as Conn's disease and similar autoimmune diseases, or in combmatton with corticosteroids where prolonged or repeated corticosteroid therapy is indicated. Finally, this invention is extremely important because It enables the safe treatment of a large group of patients with hypertension who also have secondary diseases of the immune system, various inflammations or viral Infections such as Covid where corticosteroid therapy is indicated, but difficult to implement in practice due to the negative effect of corticosteroids on blood pressure.
