The aim of the study was to evaluate the efficacy of a micronized purified flavonoid fraction in patients with primary venous disease. The study enrolled 31 patients, with varicose veins observed in a total of 47 lower extremities which were divided into 3 groups depending on the CEAP clinical class. The group of class C2 included 19 limbs, with the groups of C3 and C4 comprising 14 limbs each. The patients received a micronized purified flavonoid fraction (Detralex) in a daily dose of 1000 mg for 1 month. The venous function of the lower extremities was examined using venous photoplethysmography before and after the course of pharmacotherapy. Venous refilling time and venous half-refilling time were measured as indicators of total venous reflux.

In the overall sample of patients with clinical class C2-C4, a significant increase in venous photoplethysmography parameters was found after the course of administration of the micronized purified flavonoid fraction. Thus, the venous refilling time increased from 15.5 (11; 19) s to 19.3 (13; 25) s, the venous half-refilling time increased from 6.5 (5; 7) s to 7.5 (5; 9) s. At the same time, in the group of patients with clinical class C2 and C3, a significant increase in the venous refilling time was found, and in patients with C4, the increase was not significant. There was an inverse correlation between the increase in venous refilling time after drug exposure and the clinical class of venous insufficiency according to the CEAP, as well as the patient’s age.

Thus, the administration of the micronized purified flavonoid fraction for 1 month in primary venous disease led to a decrease in the total venous reflux. The effect of the micronized purified flavonoid fraction on the total venous reflux was higher in younger patients and in patients with a lower clinical class of the disease.

KEY WORDS: varicose veins, venous photoplethysmography, detralex, micronized purified flavonoid fraction, venous reflux, venous refilling time.
