BACKGROUND Clopidogrel is a widely prescribed drug for prevention of myocardial infarction and stroke in patients at *** inhibits thrombus formation via inhibition of the P2Y12 purinergic receptor on platelets,which is important in their activation by ***,the P2Y12 receptor has also been found to be expressed in both osteoblasts and *** evidence suggests that purinergic receptors regulate important functions of bone *** studies on the effect of clopidogrel on bone metabolism indicated potential harmful effects,but their results remain ***,clopidogrel treatment may affect bone healing,but it has not yet been *** To evaluate if continuous perioperative clopidogrel treatment has any negative effect on bone healing in the rabbit calvarial defect *** Sixteen male white New Zealand rabbits were randomly assigned in two groups:One group received daily 3 mg/kg of clopidogrel per os and the other group received the vehicle alone for a week prior to the surgical procedures;the treatments were continued for another 6 wk *** surgical procedures included generation of two circular calvarial defects 11 mm in diameter in every *** the 6-wk period of healing,postmortem radiographic and histomorphometric evaluation of the defects was *** Both the surgical procedures and the postoperative period were uneventful and well tolerated by all the animals,without any surgical wound dehiscence,signs of infection or other *** bone was formed either inwards from the defect margins or in the central portion of the defect as separated bony *** defect healing was still incomplete in both groups,the clopidogrel group had significantly improved radiographic healing ***,the histomorphometric analysis showed that bone regeneration(%)was 28.07±7.7 for the clopidogrel group and 19.47±4.9 for the control group,showing a statistically significant difference
