The side effects of antihypertensive drugs are often the subject of discussions, publications and presentations, but not in cases where they include in their “palette” or “repertoire” concepts such as generating / promoting or potentiating various types of cancer, as well as metastasis of already existing one. Unfortunately, progress within the real, clinical medicine often does not start with the desired results (from those expected within clinical observations or experimental data after administration of a particular substance or drug). Breakthroughs in medicine and progress start with the careful registration and analysis of unwanted and unexpected, unplanned results. Again, unfortunately, the analysis of it is often swept under the table, without thinking that the negative results should be the generator of progress. When the observations of certain clinical or experimental data remain insufficiently analyzed, neglected or deliberately hidden - the result is often alarming or fatal - similar to the scandals (from 2018) with Sartans and the generation of hundreds of cutaneous melanomas, as well as heterogeneous species and other cancerous forms. However, if we all focus together on the problems through the prism of the possibilities to solve them, there is a real chance to achieve a drastic decrease in the incidence of a number of tumor diseases, due to the possibility of rethinking their pathogenesis. The article is a kind of analysis and directing clinicians in the right direction in relation to an urgent need to clarify issues related to the procarcinogenic effect of drugs from the so-called group of Sartans and Thiazide diuretics. In the first mentioned drugs, the carcinogenic effect could be due to: 1) the action of the main substance of the Sartans themselves (proven in experimental conditions, but also in in vivo data) and 2) the additive, undesirable ingredients or the so-called nitrosamines arising as additional contamination within the production process. The combination of Sartans and Thiazide diuretics (plus Nitrosamines, the presence of which is not adequately tested) could in all likelihood have a fatal, mutually potentiating procarcinogenic effect, leading to the manifestation of 3 or even more cancers simultaneously. This publication presents for the first time in the world literature a patient who developed three cancers at the same time (Kaposi’s sarcoma, skin melanoma and colon cancer) after starting therapy with Valsartan and hydrochlorothiazide. Our critical analysis is focused on the regulatory authorities in the face of the FDA, EMA, but also on the National Agency for Drug Control. Attention is also paid to the non-traditional and illegal from the point of view of all ethical norms ways of influencing the pharmaceutical industry, in order to protect its positions in the framework of the daily emerging world scandals.
