The study reports about the intravenous application of Biperiden at patients with acute hypokinetic reaction suffering from schizophrenia of the paranoid-hallucinatory type. In all of the six cases examined a fast abolition of the stupor could be observed. The pathophysiological mechanisms deriving from our clinical experiences are discussed.
