Ticlopidine-d4 is intended for use as an internal standard for the quantification of ticlopidine (Item No. 20770) by GC- or LC-MS. Ticlopidine is a thienopyridine P2Y12 receptor antagonist.1 It inhibits aggregation of human platelets induced by collagen, arachidonic acid (Item No. 90010), and ADP (Item No. 16778; IC50s = 75, 600, and 1,300 μM, respectively).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.WARNING This product is not for human or veterinary use.
