An internal standard for the quantification of ticlopidine
Ticlopidine-d4 is intended for use as an internal standard for the quantification of ticlopidine by GC- or LC-MS. Ticlopidine is a thienopyridine P2Y12 receptor antagonist.1 It inhibits aggregation of human platelets induced by collagen, arachidonic acid , and ADP .2 It also inhibits ADP-induced aggregation of rat platelets and decreases thrombus weight in vivo in a rat model of arterio-venous shunt thrombosis when administered at a dose of 100 mg/kg.3 Ticlopidine (300 mg/kg) inhibits healing of acetic acid-induced gastric ulcers in rats.4 Formulations containing ticlopidine have been used in the prevention of thrombotic stroke.
