METHOD FOR PREPARING A MEDICINAL PRODUCT FOR EXTERNAL USE Russian patent published in 2022 - IPC A61K35/06 A61K33/00 A61P17/00 

FIELD: pharmaceutical industry.

SUBSTANCE: invention relates to the pharmaceutical industry, and in particular to a method for preparing a therapeutic agent for external use. A method for preparing a therapeutic agent for external use, including supplying cold, hot drinking water and medicinal water through pipelines through mixers to a tank to obtain the necessary therapeutic solution with the required temperature, characterized in that drinking water, mineral salts, Naftalan oil and/or paraffins are obtained from the production of a well producing extra-viscous oil using the steam-gravity effect method - SGE, medicinal water is obtained by mixing mineral salts, Naftalan oil and/or paraffins necessary to obtain the desired concentration of ingredients with hot drinking water, which is heated in a heat exchanger by heating part of the drinking water while utilizing the heat from the well production, and mixing hot water with cold drinking water is carried out before being fed into the tank in a mixer - jet pump, and when utilizing heat in the heat exchanger, the well products are pumped at a speed that provides a turbulent flow to prevent deposition of paraffin and oil fractions on the walls, and the water in the heat exchanger is heated to 40°-60°С to reduce the formation salts that are insoluble in water.

EFFECT: method makes it possible to simplify and reduce the cost of the process by using as a basis natural products obtained from the production of wells producing extra-viscous oil, and utilizing the heat of this product to heat water for therapeutic agents.
