Description

Troxerutin is a semi-synthetic flavonoid derivative, a hydroxyethylrutoside, known for its potent venotonic and capillary-protective properties. This compound is highly valued for its ability to improve microcirculation and reduce vascular permeability and fragility. It is a critical active pharmaceutical ingredient (API) and nutraceutical component for manufacturers in the pharmaceutical, dietary supplement, and cosmetic industries. The global market for this ingredient is driven by demand for effective vascular health solutions.

Application

• Pharmaceutical Formulations: Primary API in prescription and over-the-counter (OTC) medications for chronic venous insufficiency (CVI), hemorrhoids, varicose veins, and capillary fragility.
• Dietary Supplements: Key ingredient in capsules, tablets, and powders targeting circulatory support, leg swelling, and overall vascular health.
• Cosmetic & Skincare Products: Used in formulations for its anti-inflammatory and antioxidant properties to reduce redness, under-eye circles, and improve skin tone.
• Veterinary Medicine: Employed in veterinary pharmaceuticals for similar circulatory and anti-edema purposes in animals.
• Clinical Research: Serves as a reference standard and active compound in pharmacological studies related to angiogenesis, inflammation, and vascular biology.
