The effect of oxpentifylline (Trental') on fibrinolytic activity and plasma fibrinogen levels

Abstract

Twenty healthy volunteers were treated for 3 months with oxpentifylline (200 mg 3-times a day) or a placebo in a controlled double-blind randomized trial. The volunteers taking the oxpentifylline showed a significant increase in their fibrinolytic activity, as assessed by the dilute blood clot lysis time and fibrin plate lysis area, and a significant reduction in their plasma fibrinogen levels. No change was found in the control group. These findings suggest that oxpentifylline may be valuable in the treatment of small vessel occlusive disease associated with lowered fibrinolytic activity and raised fibrinogen levels.
