Antioxydant activity, membrane stabilizing and cytoprotective effect of dihydropyrimidin analoges are widely described in various literary sources. One of the importantant mechanisms of action of antioxidants is their antihypoxic activity. It is the ability to increase tissue resistance to hypoxia. The search for drugs to increase the body's resistance under hypoxic conditions is an actual task in experimental and clinical pharmacology.</p></sec><sec><title>Aim</title><p>Aim.
