ABSTRACT
In ten healthy, male subjects the acute effect of pentoxifylline (a methylxanthine derivative) on liver plasma flow was investigated by the extrarenal sorbitol clearance method and on cardiac output by impedance cardiography. On the placebo day liver plasma flow decreased within 4 h from 769 to 683 ml.min-1 (P less than 0.05) and on the pentoxifylline day (300 mg i.v.) it increased from 764 to 801 ml.min-1 (NS). At the end of the experiment the difference between the groups was also significant (P less than 0.05). There was no significant change in cardiac output, blood pressure or heart rate and individual changes in those values were not correlated with liver plasma flow. There was no correlation either between the plasma concentrations of pentoxifylline or its metabolites and the changes in liver plasma flow. It is concluded that, relative to the spontaneous decrease in liver plasma flow at rest on the placebo day, pentoxifylline increased splanchnic perfusion independent of any change in cardiac output.
