4 Drug and Medication Information
4.1 Drug Indication

Diosmin is used over-the-counter alone or with ingredients such as [hesperidin] and [diosmetin] to support vein and capillary function.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Diosmin is a venoactive drug supporting circulatory health through various actions on blood vessels; it supports lymphatic drainage and improves microcirculation while increasing venous tone and elasticity. For these reasons, diosmin is frequently taken by individuals with chronic venous disease to support vascular health and has been demonstrated to improve quality of life. In addition to the above effects, diosmin exerts antioxidant activity and scavenges oxygen free radicals, reducing levels of oxidative stress normally detected through biomarkers such as prostaglandins isoprostane precursors. In one clinical study, mean content of TNF alpha, VEGF-C, VEGF-A IL-6, in addition to FGF2 were decreased by after the therapy with diosmin; findings were statistically significant. Additionally, a decrease in edema and mean leg circumference of patients taking diosmin for three months was observed in a clinical study. Diosmin has been demonstrated to enhance the metabolism of glucose in diabetic disorders.


5.2 ATC Code

C - Cardiovascular system

C05 - Vasoprotectives

C05C - Capillary stabilizing agents

C05CA - Bioflavonoids

C05CA03 - Diosmin


5.3 Absorption, Distribution and Excretion

Absorption

Diosmin is rapidly absorbed in the gastrointestinal tract. After a 900 mg single oral dose in a study using liquid chromatography with tandem mass spectrometry (LC-MS/MS) method, Cmax was 4.23.8 ngmL-1, Tmax was 18.79.9 hours, and AUC0~96 was 185.4166.2 ngmL-1 in healthy volunteers. Another pharmacokinetic study of 5 adults revealed a Cmax of 41794.1 ng/dL.


Route of Elimination

Pharmacokinetic data show absence of urinary elimination for diosmin and its aglycone diosmetin. Minor metabolites are found to be eliminated in the urine as glucuronic acid conjugates.


Volume of Distribution

A pharmacokinetic study of 5 adults revealed a volume of distribution of 62.17.9 L.


5.4 Metabolism/Metabolites

Degradation products of diosmin such as alkyl-phenolic acids confirm a metabolic pattern similar to that of other flavonoids.


5.5 Biological Half-Life

Diosmin half-life ranges from 26 to 43 hours. One study using a liquid chromatography with tandem mass spectrometry (LC-MS/MS) method after a single 900 mg dose of diosmin demonstrated a half-life of 60.285.7 hours in healthy volunteers.


5.6 Mechanism of Action

Diosmin helps to maintain circulatory system structure and function, particularly vein strength and competence. The molecular mechanism of action of diosmin has not been established. Several resources indicate that diosmin binds to the aryl hydrocarbon receptor, however clinical relevance to vascular function is unknown. One study demonstrates that oral diosmin exerts effects on the in vitro metabolism of noradrenaline by varicose veins, potentially benefitting vascular health.
