Effects of danazol on coagulant activity in the rat.

Abstract

Coagulation factor activity was evaluated in female rats treated with danazol. Following 30 days of treatment, slight decreases in factor VII and X activities were noted. After 60 days, a prolongation of the prothrombin time, as well as a decrease in factor VII, was noted. The data suggest that in the rodent, danazol has minimal effects on coagulation activity.
