Usage
Troxerutin is a vasoprotective agent, a flavonoid derivative used to treat conditions related to poor blood circulation. It is commonly prescribed for:
- Chronic venous insufficiency (CVI)
- Varicose veins
- Hemorrhoids
- Diabetic retinopathy
It works by:
- Strengthening capillary walls
- Reducing capillary permeability and leakage
- Improving blood flow by decreasing blood viscosity
- Acting as an antioxidant
Alternate Names
- Venoruton
- Troxevasin
- Trihydroxyethylrutoside
How It Works
Pharmacodynamics: Troxerutin exerts its therapeutic effects primarily through its actions on the vascular system. It strengthens capillary walls, reduces capillary permeability, improves blood flow by decreasing viscosity, and exhibits antioxidant properties. These actions contribute to alleviating symptoms associated with venous insufficiency, such as edema, pain, and leg heaviness.
Pharmacokinetics: Troxerutin is readily absorbed after oral administration. It is partially metabolized in the liver by glucuronidation. It is widely distributed in the body, with preferential accumulation in the endothelium of blood vessels. The elimination half-life is approximately 18.3 hours, and excretion occurs primarily through the feces, with a smaller portion eliminated in the urine.
Dosage
Standard Dosage
Adults:
Oral: 600-1200 mg daily, divided into multiple doses, usually taken with meals.
Topical: Apply gel to the affected area 2-3 times daily.
Children:
Safety and efficacy not established; use is generally not recommended.
Special Cases:
Elderly Patients: No specific dosage adjustments are typically required, but start with a lower dose and monitor for side effects. Consider renal/hepatic function.
Patients with Renal Impairment: Use with caution; dose adjustment may be needed.
Patients with Hepatic Dysfunction: Use with caution; dose adjustment may be needed.
Patients with Comorbid Conditions: Caution advised for patients with respiratory disease, heart disease, epilepsy, or low blood pressure.
Clinical Use Cases
Dosages for intubation, surgical procedures, mechanical ventilation, ICU use, and emergency situations are not specifically addressed in the provided information.
Dosage Adjustments
Dose modifications may be necessary based on individual patient factors, including renal/hepatic dysfunction and other medical conditions.

Contraindications
- Hypersensitivity to troxerutin or any of its components
- First trimester of pregnancy (generally avoided)
- Use with caution during breastfeeding (limited data on safety)
- Children under 18 (safety and efficacy not established)
Drug Interactions
- Nonsteroidal anti-inflammatory drugs (NSAIDs): May increase the risk of gastrointestinal side effects.
- Anticoagulants (e.g., warfarin): May increase the risk of bleeding.
- Medications metabolized by the liver: Troxerutin may interfere with liver enzyme activity.
- Cefuroxime, Cephalexin, Cefapirin, Cefazolin, Cefdinir, Cefditoren, Cefepime, Cefixime, Cefprozil, Cefradine, Ceftaroline fosamil, Ceftazidime, Cefmenoxime, Cefmetazole, Cefonicid, Cefoperazone, Ceforanide, Cefotaxime may decrease efficacy of Troxerutin.
- Celecoxib may increase the risk of bleeding.
- Chenodeoxycholic acid may increase the risk of bruising.
Pregnancy and Breastfeeding
Pregnancy: Troxerutin is generally avoided during the first trimester and used with caution during subsequent trimesters due to limited safety data.
Breastfeeding: Consult a healthcare professional before using troxerutin while breastfeeding, as there is insufficient information on its safety in this population.
Drug Profile Summary
Mechanism of Action: Vasoprotective agent, improves capillary integrity, reduces permeability, decreases blood viscosity, and acts as an antioxidant.
Side Effects: Common: GI disturbances, skin reactions, headache, flushing. Rare but serious: Allergic reactions.
Contraindications: Hypersensitivity, first trimester of pregnancy, use with caution during breastfeeding, children under 18.
Drug Interactions: NSAIDs, anticoagulants, medications metabolized by the liver, certain antibiotics may decrease efficacy or increase risk of adverse effects.
Pregnancy & Breastfeeding: Generally avoided during the first trimester of pregnancy and used with caution thereafter. Consult a doctor before using while breastfeeding.
Dosage: Adults: 600-1200 mg daily, divided into multiple doses. Topical: Apply gel 2-3 times daily. Dosage adjustments may be necessary in special cases.
Monitoring Parameters: Assess for signs of venous insufficiency, monitor for side effects, and evaluate liver and kidney function if necessary.
Popular Combinations
Combinations with other phlebotonics or anti-inflammatory agents may be used, but clinical evidence supporting these combinations is limited.
Precautions
- Pre-existing medical conditions: Use with caution in patients with liver or kidney impairment, respiratory disease, heart disease, epilepsy, or low blood pressure.
- Pregnant Women: Avoid during the first trimester, use with caution in subsequent trimesters.
- Breastfeeding Mothers: Consult a doctor before use.
- Children & Elderly: Not recommended for children under 18. For elderly patients, start with a lower dose and monitor for side effects.
- Lifestyle Considerations: Avoid alcohol as it may exacerbate drowsiness. Caution when driving or operating machinery if drowsiness or vision disturbances occur.
FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Troxerutin?
A: Adults: 600-1200 mg daily, divided into multiple doses. Topical: Apply gel 2-3 times daily. Children: Not recommended. Elderly: Start with a lower dose and monitor. Renal/Hepatic impairment: Dose adjustment may be necessary.
Q2: What are the common side effects of Troxerutin?
A: Gastrointestinal issues (nausea, stomach pain, diarrhea), skin reactions (rash, itching), headache, flushing, fever, and joint pain.
Q3: Is Troxerutin safe to use during pregnancy?
A: It’s generally avoided during the first trimester. Use with caution during subsequent trimesters only if the potential benefit justifies the potential risk to the fetus.
Q4: Can I use Troxerutin while breastfeeding?
A: Limited information is available about its safety during breastfeeding. It’s crucial to consult with a healthcare professional before using Troxerutin while breastfeeding.
Q5: How does Troxerutin work?
A: It strengthens capillary walls, reduces capillary permeability, decreases blood viscosity, improves blood flow and has antioxidant properties.
Q6: What conditions is Troxerutin used to treat?
A: Primarily chronic venous insufficiency (CVI), varicose veins, hemorrhoids, and diabetic retinopathy.
