Dexfenfluramine is a variation of fenfluramine which is used for weight reduction. The aim of the study is to determine the hemodynamic and structural effects of this drug on pulmonary circulation. An experimintal study was carried out with New Zealand Rabbits. A control group (n=30) and an experimintal group (n=20) was constituted. A four-week normal diet for control group and dexfenfluramine plus normala diet for experimental group were applied. Body weights and pulmonary artery pressures of groups were recorded and lungs were collected for pathologic examination. In experimintal group; Dexfenfluramine raised systolic pulmonary artery pressures significantly (p0.05). Weight reduction was obvious (f= 8.522, p
