Which dose of calcium dobesilate is more effective and safe in chronic venous insufficiency? Multicenter retrospective clinical trial

ObjectivesThis study aimed to evaluate the effectiveness and safety of different dosages of calcium dobesilate in the management of Chronic Venous Insufficiency (CVI) among patients in CEAP classes C3-C4.MethodsA comprehensive multicenter retrospective analysis was conducted, including patients aged 18-70 with CEAP class C3-C4 CVI. Participants were divided into two groups: one receiving 500 mg of calcium dobesilate twice daily and the other 1000 mg twice daily. Patient progress was monitored using the Global Index Score, CIVIC-20 Score, and precise measurements of ankle and calf circumferences over a 12-month period.ResultsThe higher dosage group (1000 mg twice daily) showed significant improvements in both symptom relief and edema reduction. Ankle circumference reduced notably at 6 months, while calf circumference and overall quality of life, measured by the Global Index Score, showed significant improvement by 12 months compared to the lower dosage group.ConclusionsHigher doses of calcium dobesilate markedly enhance the management of CVI symptoms and reduce edema more effectively than lower doses, particularly in patients with advanced CVI. These findings support the use of higher dosages for optimal treatment, though further research is needed to fully evaluate long-term safety.
