The article is devoted to the search pharmaceuticals, able to increase the organism resis-tance to hypoxia. On Wistar rats conducted trials of drugs peptide of origin and their combinations on hypobaric effect. It is experimentally established, all the studied drugs and their combinations were highly active, which manifested itself in the increase of organism resistance experimental rats to acute hypobaric hypoxia compared with control. Most active among the subjects of drugs Pept-9, Pept-10 and Pept-11, under the influence of which on the 21st day after the introduction of the life-time of the «height» in experimental animals has been extended more than in 3 times. Pept-10 and Pept-11 are not only maintained a high level of anti-hypoxia effect within 7 days after the termination of their introduction, but also exceeded the maximum rate, shown on the 21st day of research. Thus, the obtained data show that the investigational agents peptide of origin and their combinations are anti-hypoxia trials.
