Gabexate mesilate (FOY) therapy of disseminated intravascular coagulation due to sepsis.

Gabexate mesilate (FOY), a synthetic serine proteinase inhibitor, has an anticoagulant activity in the absence of antithrombin-III. We investigated FOY therapy for the treatment of disseminated intravascular coagulation (DIC) associated with sepsis in 15 patients (group F), and compared it with heparin therapy in 8 patients (group H). Successful treatment was observed in 13 patients in group F and in 4 patients in group H. The efficacy of the therapy in both groups was not significantly different. However, in patients whose antithrombin-III values were less than 20 mg/dl at the initiation of the therapy, FOY therapy was successful in 6 of 7 patients, whereas heparin therapy was not at all successful in 4 patients (rho less than 0.05). We conclude that FOY can be used as effectively as heparin for the treatment of DIC, and that FOY therapy is superior to heparin therapy in DIC associated with decreased antithrombin-III.
