“In addition, flurazepam and not diazepam inhibited the release of arachidonic acid from platelet phospholipids in a concentration dependent manner.”
“One minute preincubation with flurazepam (3-300 microM) or diazepam (3-300 microM) inhibited platelet aggregation, serotonin secretion and prostaglandin synthesis induced by ADP (1-5 microM), epinephrine (1-5 microM), and arachidonic acid (600-1000 microM).”
“These findings suggest that: (… C; (b) flurazepam … arachidonic acid , its conversion into prostaglandins and by blocking the action of prostaglandins on platelets; (c) diazepam does not inhibit thrombin-induced …-mediated activation of platelets; and (e) neither diazepam nor flurazepam achieve their antiplatelet actions by affecting platelet cyclic nucleotide levels.”
