Suloctidil: long-term trial in the aged. Study of microcirculation, viscosity, red cell deformability, fibrinolysis and lipid fractions.

15 aged patients with clinical and laboratory evidence of cerebrovascular insufficiency and/or myocardial sclerosis were given suloctidil (Locton) at the daily dose of 200 mg X 3, for 180 days, under the conditions of an open trial. Blood and plasma viscosity, red cell deformability, total lipids, cholesterol, triglycerides, fibrinolysis (plasminogen, antiplasmin, euglobulins with and without activator, fibrinogen), and capillaroscopic parameters in the small conjunctival vessels (artery, vein, and capillary diameter, appearance of collaterals, red cell aggregation and flow homogeneity) were evaluated. After 30 days of treatment and particularly at the end of the trial a significant improvement of almost all these parameters was observed. Tolerance was always excellent.
