Effect of lomustin on some platelet functions in vitro.

The effect of lomustin on platelet functions was investigated in vitro using a wide battery of tests. Lomustin was found to act as a specific inhibitor of platelet aggregation, release reaction and clot retraction and to induce acquired thrombocytopathy. Thus, impairment of platelet functions might play a role in hemorrhagic complications accompanying lomustin therapy in some cases.
