title: Activity of plafibride on erythrocyte deformability.
abstract: N-2-(p-Chlorophenoxy)-isobutyryl-N'-morpholinomethylurea (plafibride, Idonor, Perifunal, Plafibrinol) is an acid derivative of morpholinomethylurea and clofibric acid. In these studies the effects of plafibride on haemorheological properties have been observed. The studies have been carried out in different animal species (rat, rabbit and dog), and in human volunteers. Under these circumstances, plafibride has shown itself to be highly active in all the animal species and in humans, as well as with the two laboratory methods used for determination of erythrocyte deformability, these being Teitel's method, which evaluates the deformative capacity of erythrocytes when forming compact groups, and the method of Schmid-Schoenbein in which the deformability of individual erythrocytes is measured by passage through fine capillaries. In trials in volunteers, the increase in erythrocyte deformability is notable even 5 days after the last administration. In addition to its microhaemorheological activity, plafibride has been shown to have effects on platelet aggregation and hyperlipaemia.
