In present medical practice adaptogens and antihypoxants are a promising, but still insufficiently studied group of medicines. The largest evidence base among plant adaptogens was developed for ginseng, aralia, eleutherococcus, lemongrass, rhodiola, leuzea, sterculia. Antihypoxants, like trimetazidine, meldonium, succinic and -aminobutyric acid medications are included in the clinical guidelines. They have the most pronounced antihypoxic effects in a variety of diseases and pathological conditions, accompanied by impaired energy metabolism in the tissues. But their effect is not always high due to the variety of etiological factors causing hypoxia. Tetrahydropyrido[2,1-b][1,3,5]thiadiazine derivatives characterized by various pharmacodynamic effects with low toxicity which opens up prospects for a detailed further study. In animal experiments, the most pronounced adaptogenic and antidepressant effects is exerted by compounds TD-0348 and TD-0479, superior in strength to the antihypoxants used in modern clinical practice, the classic plant adaptogen ginseng.
