The following data have been obtained in a number of studies:

– The research by V.V. Bulanova1 showed a 55% decrease in the incidence of acute respiratory infections when taking Trekrezan. Significant increase in the number of lymphocytes indicates a positive effect of Trekrezan on the immune status of the body;

– The work of A.V. Bolekhan2 proved the effect of Trekrezan on immunity indicators in case of acute bronchopulmonary inflammation due to an increase in lymphokine-producing function of lymphocytes in the inhibition of leukocyte migration with concanavalin A by 19% and with phytohemagglutin by 10%, and neutrophil activity increased by 7%;

– The study of A.A. Elistratova3 proved the maintenance of high level physical and mental performance under extreme conditions. At low temperatures, Trekrezan had a positive effect on CVS, stimulating working capacity and increasing the endurance of the muscle system. In case of temperature increase, the use of Trekrezan allowed to improve indicators of the state of the respiratory system — respiratory rate, respiratory minute volume, Stange test, Gencha test.

Thus, Trekrezan is a unique medication combining pronounced immunomodulatory and adaptogenic properties. The drug is useful in case of commonly occurring asthenic conditions that come with colds and in case there is a frequent need to increase the body resistance to climate loads and to restore the working capacity.
