Abstract：
:The effect of the combined oral administration of pentoxifylline (pof) and low dose acetylsalicylic acid (ASA) was evaluated with the help of the laser-induced thrombosis in rat mesenteric arterioles. Laser-induced thrombosis is inhibited in a dose-dependent way by both drugs. The administration of ASA, either simultaneously with or 1 hour prior to pof, does not show any effects in the laser model. On the contrary, the administration of pof followed 1 h later by ASA not only exhibited a significant effect but also produced a supraadditive inhibition of the laser-induced thrombus formation. Specific investigations concerning the time interval between the administration of both drugs determined that a significant effect can be achieved only after an interval of 30 to 90 minutes (principle of HWA 5112). The striking results could also be shown in diseased animals after sequential chronic administration of pof 1 h prior to ASA. HWA 5112 exhibits significant effects on laser-induced thrombus formation in the following chronic animal models: 1. adjuvant arthritic rats, 10----1 mg/kg for 21 days; 2. spontaneously hypertensive stroke-prone rats, 10----1 mg/kg three times within 24 h; 3. cholesterol-induced atherosclerosis in rabbits, 10----1 mg/kg for 14 days. The reported data clearly demonstrate that the sequential drug administration of first pentoxifylline followed 30 to 90 min later by ASA exhibits a supraadditive antithrombotic effect.
