[The pharmacological correction of hemodynamics during the simulation of the early period of adaptation to weightlessness].

Investigations of volunteered subjects in whom antiorthostatic hypokinesia was modeled by tilting the cranial end of the body by -15 degrees were to answer whether pharmacological countermeasures of the vestibular/autonomous syndrome (motion sickness, sea sickness) alter the orthostatic tolerance and cardiovascular parameters. As was stated, the drugs allow controlled correction of hemodynamic resistance to the head-down tilt. Ephedrine, phencarol, ephedrine combined with scopolamine and pipolphen, and stugeron normalized cerebral circulation.
