Abstract

Piperacillin is a new semisynthetic penicillin which is similar in structure to carbenicillin and ticarcillin. Since the latter antibiotics have been shown to cause abnormalities in hemostasis, we studied the effects of piperacillin on blood coagulation and platelet function. Fifteen healthy volunteers received the drug in doses of either 100, 200, or 300 mg/kg per day for a period of 7 days. Serial studies showed no abnormalities in blood coagulation in any subject. Decreased platelet aggregation responses to adenosine diphosphate, epinephrine, collagen, and arachidonic acid were commonly noted, but prolongation of the bleeding time occurred in only 3 of 15 subjects after 7 days of piperacillin administration. These results suggest that although piperacillin also induces platelet dysfunction, these effects may be less than those caused by ticarcillin or carbenicillin at an equivalent dosage.
