Coagulation and fibrinolysis in post-menopausal women treated with Org OD 14.

The effects of a new synthetic steroid Org OD 14 on the haemostatic mechanism were investigated in 60 post-menopausal women, randomly allocated to 12 weeks of treatment with either 2.5 mg/day of Org OD 14 or a placebo in a double-blind, group-comparative study. Assessments were made 2 weeks before and just prior to the start of treatment, at weeks 6 and 12 during treatment, and 2 weeks after its cessation. No significant differences between the two groups were found with regard to prothrombin time, kaolin cephalin clotting time (KCCT), clotting factors VII, VIII and X, white blood count (WBC) or transaminases (ASAT, ALAT). The following statistically significant differences were seen in the Org OD 14 group: higher plasminogen, antithrombin III, haemoglobin, haematocrit and platelet count, and increased fibrinolytic activity on fibrin plates, as well as lower fibrinogen and alkaline phosphatase values. These findings indicate that Org OD 14 displays no adverse effects on coagulation, while changes in fibrinolysis seem to be beneficial for post-menopausal women.
