warfarin and Hemostatic-Disorders

A single intraperitoneal administration of cisplatin in the MTD to outbred female mice disturbed hemostasis and formed the procoagulant phenotype of hemostatic potential on days 7-10 culminating in a pronounced hypocoagulation on day 15. Hemostasis was corrected with warfarin and an extract containing furocoumarins composed of isopimpinellin (42.97%), bergapten (35.18%), and xanthotoxin (15.41%). The extract was standardized with gas chromatography-mass spectrometry, thin-layer chromatography, and HPLC. Furocoumarins and reference drug warfarin were administered intragastrically during 4 days starting on day 6 after the administration of cisplatin. Both furocoumarins and warfarin corrected hypercoagulation on days 7-10. On day 10, furocoumarins normalized coagulation, whereas warfarin resulted in hypocoagulation. On days 15-30, no effects of warfarin were observed. furocoumarins corrected hypocoagulation on days 15-20 with prolongation of this effect up to experimental day 30.
