ABSTRACT
The effects of metoclopramide( MCP ) on the physiologic properties of guinea pig papillary muscles and the hemodynamics in anesthetic dogs were studied. MCP decreased contractility, increased the epinephrine concentration inducing automaticity and shifted the voltage-time plot to the right. But the functional refractory period was prolonged. Furthermore, the contractility and automaticity of the right auricle were decreased. MCP 5 mg/kg iv increased cardiac index (CI), systolic blood pressure ( SBP ), diastolic blood pressure ( DBP ), left ventricular systolic pressure ( LVSP ), maximal rate of change of intraventricular pressure ( dP/dtmax ), and total peripheral resistance ( TPR ) while MCP 10mg/kg iv decreased SBP, DBP, LVSP, dP/dtmax and TPR except increase of CI.
