4.4 Special warnings and precautions for use
This medicinal product contains lactose monohydrate. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
The efficacy and safety of the preparation have not been studied in the following groups/conditions, which has to be taken into account when the preparation is used:
- children and adolescents (under 18 years).
- hepatic and/or renal impairment.
4.5 Interaction with other medicinal products and other forms of interaction
No pharmacokinetic and pharmacodynamic interaction studies have been performed with diosmin and other medicinal products or with diosmin and food.
In the post-marketing experience, no interactions of diosmin and other medicinal products have been reported.
4.6 Fertility, pregnancy and lactation
Pregnancy
Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonic or foetal development (see section 5.3).
The available clinical experience in pregnant women is too limited to exclude a risk, and administration of diosmin is therefore not recommended during pregnancy.
Breastfeeding
It is not known whether diosmin is excreted into human milk. Therefore, in the absence of further information, this medicinal product should not be administered during breastfeeding.
Fertility
Reproductive toxicity studies in rats show no effect on fertility. No clinical data are available about the use of diosmin and fertility.
4.7 Effects on ability to drive and use machines
No studies on the effects on the ability to drive and use machines have been performed.
However, based on the overall safety profile, diosmin has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
Gastrointestinal adverse reactions were the most common reported adverse drug reactions. They include nausea, dyspepsia, vomiting and diarrhoea.
The most serious ADR associated with the use of diosmin was angioedema.
The following headings are used to rank the ADRs by frequency: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to < 1/1,000), very rare (< 1/10,000), not known (cannot be estimated from the available data). Within each frequency grouping, ADRs are presented in order of decreasing seriousness.

- PHARMACOLOGICAL PROPERTIES 5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Vasoprotectives, bioflavonoids
Mechanism of action
Activity on veins
This medicinal product reduces the predisposition of veins to vasodilate and reduces venous stasis.
Activity on microcirculation
This product reduces capillary permeability and increases capillary resistance.
Pharmacodynamic effects
Pharmacological activity of this medicinal product in humans has been substantiated by controlled, double-blind clinical studies and also by objective and quantitative methods in investigating the influence of the active substance on venous haemodynamics.
Effects on venous tone
This medicinal product enhances venous tone and therefore, reduces the capacitance, distensibility and stasis of blood: venous occlusal mercurial plethysmography indicates reduction of emptying time of veins.
The final effect is a reduction in venous hypertension in patients with venous insufficiency.
Effects on lymphatic system
Diosmin stimulates the lymphatic activity, improving drainage of the interstitial space and increasing lymphatic flow. The administration of 1 g a day for 28 days is capable of reducing lymphatic capillary diameter and intralymphatic pressure, improving the number of functioning lymphatic capillaries, in patients with severe chronic venous insufficiency, without ulcers.
Anti-inflammatory effects
Diosmin reduces various inflammation indexes in peripheral microvascularisation. In vitro and in animal studies, diosmin reduces the release of different inflammation prostaglandin mediators E2 and F2α (PGE2 and PGF2α) and thromboxane A2 (TxA2). Consequently, it inhibits the adhesion of leukocytes to the vascular wall and reduces capillary permeability and resistance, thus favouring venous return.
Effects on microcirculation
Controlled, double-blind clinical studies demonstrate statistically significant difference between diosmin and placebo. In patients with capillary fragility, diosmin treatment increases capillary resistance and reduced the clinical manifestations.
A decrease in capillary permeability was also observed after administration of 1 g of daily diosmin for 6 weeks, with respect to placebo, using technetium-labelled albumin, or plethysmography.
Clinical efficacy and safety
Controlled, double-blind clinical studies demonstrate therapeutic activity of the product in adults as a short-term treatment of symptoms of established chronic venous insufficiency (CVI) adjuvant to conventional treatment of CVI.
5.2 Pharmacokinetic properties
Absorption
Following oral administration, diosmin is rapidly hydrolyzed in the intestine by intestinal flora and absorbed as its aglycone derivative, diosmetin. Oral bioavailability is approximately 57.9%.
Distribution
Diosmetin has a volume of distribution of 62.1 L indicating a broad distribution into tissues.
Biotransformation
Diosmetin is extensively metabolized to phenolic acids or to its glucuronide derivatives of aglycone that are eliminated in urine.
The major metabolite found in urine is m-hydroxyphenylpropionic acid which is mainly eliminated in its conjugated form. Metabolites found in small quantities include phenolic acids corresponding to 3-hydroxy-4 methoxybenzoic acid, 3-metoxy-4-hydroxyphenylacetic acid and 3,4-dihydroxybenzoic acid.
Elimination
The elimination half-life of diosmetin showed a mean value of 31.5 hours, ranging between 26 and 43 hours. In studies with 14C radiolabelled diosmin, 34% of the dose is found in urine and faeces after 24 hours and approximately 86% of the dose were found in urine and faeces after 48 hours.
5.3 Preclinical safety data
Oral administration in mice, rats and monkeys of doses 180 times higher than the therapeutic dose in humans reveals no toxic or lethal effect.
There was no evidence of embryotoxicity or teratogenic effects in studies in rats. Reproductive toxicity studies in rats show no effect on fertility. No impairment of the reproductive function was found in rats after administration of an oral dose representing 37 times the daily therapeutic dose or concerning fertility of animals, embryotoxicity, and perinatal and postnatal development of the generation born to treated parents.
In-vitro and in-vivo tests reveal no mutagenic potential.
