Abstract: | Pharmacological effects of 3-bis(3,3-diphenylpropyl)-amino]-propan-1-ol-hydrochloride (PF-244) mainly on cerebral and cardiovascular systems, were studied. PF-244 indicated a potent cerebral vasodilation effect and a marked increase in oxygen supply to cerebral tissue with only weak inotropic action and depressor effect. This cerebral vasodilation was more potent and specific than that of papaverine hydrochloride in regional cerebral flow. PF-244 also indicated an antibarium action, although it did not show the properties related to the cholinergic and/or adrenergic mechanism. PF-244 appears to be one of the potent cerebral vascular dilators, and the nature of its mechanism was discussed. |
