Active ingredients: Diosmin
DAFLON 500 mg film-coated tablets
Indications Why is Daflon used? What is it for?
Symptoms attributable to venous insufficiency; states of capillary fragility.
Pharmacodynamic properties
Pharmacotherapeutic group: Vasoprotector and venotonic.
ATC code: C05CA03
Pharmacology
The product carries out its activity:
- at the level of the veins, decreasing their distensibility and reducing stasis;
- at the level of microcirculation, normalizing permeability and increasing capillary resistance.
Clinical Pharmacology
The pharmacological properties of the product have been confirmed in humans by double-blind studies conducted with methods that have made it possible to object and quantify its activity on venous hemodynamics.
Dose / effect relationship:
The existence of statistically significant dose / effect relationships was established on the basis of venous plethysmographic parameters: capacity, distensibility and emptying time. The best dose-effect ratio was obtained with 2 tablets.
Venotonic activity:
Increase in venous tone: strain gauge plethysmography shows a decrease in venous emptying times.
Microcirculatory activity
The activity evaluated from double-blind controlled studies is statistically significant compared to placebo.
In patients with capillary fragility, capillary resistance controlled by angiosterrometry increases.
Clinic
The therapeutic activity of the drug, in the treatment of chronic functional and organic venous insufficiency of the lower limbs, is demonstrated by double-blind controlled studies.
Pharmacokinetic properties
In man after oral administration of carbon14-labeled diosmin, it is observed that:
- excretion is essentially fecal while urinary excretion represents, on average, 14% of the quantity administered;
- the elimination half-life is 11 hours, the product is extensively metabolised, as demonstrated by the presence of different acid phenols in the urine.
