Efficacy of MPFF 1000 mg oral suspension on CVD C0s-C1-related symptoms and quality of life.Int Angiol. 2019 Apr; 38(2):83-89.IA
To show the efficacy of micronized purified flavonoid fraction (MPFF) 1000 mg in the mild cases of chronic venous disorders (CVD), i.e. in C0s-C1 patients according to the CEAP classification.
In an international, randomized, double-blind, parallel-group study, symptomatic C0s to C4 patients according to the Clinical Etiological Anatomic Pathophysiologic (CEAP) were treated for 8 weeks by either MPFF 1000 mg once daily or MPFF 500 mg twice daily. The present post-hoc analysis is focused on the efficacy of MPFF at the daily doses of 1000 mg in the population of mild cases of the CVD (C0s-C1 patients) on lower limb discomfort, leg pain and leg heaviness using a 10-cm Visual Analog Scale (VAS), and on quality of life (QoL) using CIVIQ-20.
In the 256 patients of the C0s-C1 subset of the study patients, lower limb discomfort improvement measured on VAS was clinically and statistically significant: -2.87±2.38 cm in the MPFF 1000 mg group and -3.30±2.36 cm in the MPFF 500 mg group (P<0.001 in both groups). Leg pain and leg heaviness VAS improved similarly: -2.77±2.58 cm in the MPFF 1000 mg group and -3.45±2.38 cm in the MPFF 500 mg group (P<0.001 in both groups), and -2.91±2.47 cm in the MPFF 1000 mg group and -3.47±2.33 cm in the MPFF 500 mg group (P<0.001 in both groups). The quality of life assessed by the CIVIQ-20 questionnaire improved significantly in both treatment groups from baseline to W8 with a mean changes of global index score of -16.53±14.18 in the MPFF 1000 mg group and -18.78±18.14 in the MPFF 500 mg group (P<0.001).
MPFF at the daily dose of 1000 mg was shown to have a similar efficacy in mild CVD cases (C0s-C1 patients) as in the whole spectrum of patients from the main study, with a very good safety profile. These result further illustrates the interest of MPFF in the management of the mild cases of the disease at a daily dose of 1000 mg.
