CIPFLON

Indications

• Chronic venous insufficiency
• Hemorrhoids
• Leg edema
• Varicose veins

Dosage

Children: Refer to the BNF for Children for specific dosing information.

Adults: Refer to the BNF for specific dosing information.

Mechanism of action

Diosmin helps to maintain circulatory system structure and function, particularly vein strength and competence. Although the molecular mechanism of action is not fully established, diosmin is suggested to bind to the aryl hydrocarbon receptor, although the clinical relevance to vascular function remains unclear. It has been observed to influence the metabolism of noradrenaline in varicose veins, potentially benefiting vascular health.

Pharmacodynamics

Diosmin supports circulatory health through multiple mechanisms, including improving lymphatic drainage, enhancing microcirculation, and increasing venous tone and elasticity. It has shown to reduce oxidative stress by scavenging free radicals and lowering levels of inflammatory markers such as TNF alpha and IL-6. Clinical studies have demonstrated a reduction in edema and leg circumference in patients with chronic venous conditions after diosmin therapy.

Pharmacokinetics

Diosmin is well-absorbed from the gastrointestinal tract and undergoes extensive metabolism, primarily in the liver. The elimination half-life and specific metabolic pathways have not been extensively detailed, but it is known to be excreted in urine. The pharmacokinetic parameters may vary based on individual patient factors.

Adverse effects

• Gastrointestinal discomfort
• Nausea
• Diarrhea
• Headache
• Allergic reactions

Precautions

• Use with caution in patients with hypersensitivity to diosmin or any of its components.
• Consult a healthcare provider before use in patients with underlying health conditions.

Pregnancy

The safety of diosmin in pregnancy has not been established. Use only if clearly needed and after assessing risks and benefits.

Breast-feeding

It is unknown whether diosmin is excreted in human milk. Caution is advised when administering to nursing mothers.

Storage

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

Formulations

• Diosmin 500 mg tablets
• Diosmin 1000 mg tablets

Indications

• Chronic venous insufficiency
• Hemorrhoids
• Peripheral vascular disorders
• Symptoms of leg swelling and pain

Dosage

Children: Refer to established guidelines or consult with a healthcare professional for appropriate dosing.

Adults: Refer to established guidelines or consult with a healthcare professional for appropriate dosing.

Mechanism of action

Hesperidone is believed to exert its effects by enhancing venous tone and reducing capillary permeability. It may act through the modulation of inflammatory pathways and oxidative stress, promoting vasodilation and improving microcirculation. The pharmacological action is primarily attributed to its flavonoid structure, which allows it to scavenge free radicals and inhibit pro-inflammatory mediators.

Pharmacodynamics

Hesperidone has been shown to improve symptoms of venous insufficiency, such as leg swelling and pain, by enhancing venous return and promoting lymphatic drainage. Its antioxidant properties contribute to cellular protection against oxidative damage, which is important in managing chronic vascular conditions.

Pharmacokinetics

Hesperidone is absorbed after oral administration, with peak plasma concentrations occurring within a few hours. It is metabolized in the liver, with a bioavailability that may be influenced by food intake. The elimination half-life is variable, and the compound is primarily excreted via the kidneys. Its pharmacokinetic profile may be affected by individual factors such as age, liver function, and concurrent medications.

Contra-indications

• Hypersensitivity to hesperidone or any of its components
• Severe liver impairment
• Severe renal impairment

Adverse effects

• Drowsiness
• Dizziness
• Dry mouth
• Constipation
• Blurred vision
• Weight gain
• Extrapyramidal symptoms
• Tardive dyskinesia

Interactions

• CNS depressants (e.g., alcohol, benzodiazepines) may enhance sedative effects
• Anticholinergic drugs may increase the risk of adverse effects
• Potential interactions with drugs that affect liver enzymes

Precautions

• Use with caution in patients with a history of seizures
• Monitor for signs of tardive dyskinesia during long-term use
• Use in elderly patients may require dose adjustment due to increased sensitivity

Pregnancy

There is insufficient data on the use of hesperidone during pregnancy. It should only be used if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

Hesperidone is excreted in breast milk. Caution is advised when administering to breastfeeding women, and monitoring of the infant may be necessary.

Storage

Store in a cool, dry place, away from direct sunlight and moisture. Keep out of reach of children.

Formulations

• Tablets
• Oral solution

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.

Pharmacodynamics

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.
