title: [Pharmacological studies of antipsychotic drug, penfluridol. 2. General pharmacological properties].
abstract: General pharmacological properties of penfluridol (TLP-607) a long-acting antipsychotic drug, were examined in experimental animals and the following results were obtained. 1) TLP-607 produced a lowering of arterial blood pressure and bradycardia but had almost no effect on respiration and peripheral blood flow. 2) TLP-607 slightly hypertension induced by dopamine, adrenaline and noradrenaline, but had no effect on hypotension induced by acetylcholine and histamine. 3) Antagonistic actions of TLP-607 on such spasmogens as acetylcholine, histamine and barium chloride were slightly stronger than those of haloperidol and chlorpromazine. 4) TLP-607 had neither ganglionic nor neuromuscular blocking action. 5) TLP-607 had a slight or no effect in the following experiments; protection against stomach ulcer, activity of ileum and uterus in vivo and in vitro, urinary volume and electrolytes excretion, and gastro-intestinal propulsion. These results suggest that TLP-607 has no striking peripheral actions in experimental animals.
