Target Pharmaceutical Applications

Diosmin and flavonoid mixtures serve as foundational elements in vascular medicine, providing critical therapeutic support for complex circulatory pathologies.

Chronic Venous Insufficiency (CVI)

Diosmin targets the microcirculatory system to reduce capillary permeability and prevent venous stasis. Formulations containing Diosmin significantly alleviate the symptoms of CVI, including heavy legs, lower limb edema, nocturnal cramps, and persistent vascular tension.

Varicose Vein Formulations

By strengthening the venous wall structure and increasing venous tone (venotonic action), Diosmin helps slow down the progression of varicose veins. It reduces the inflammatory response of leukocytes on the endothelial lining, preventing structural degradation of the vein walls.

Hemorrhoid Formulations

In acute hemorrhoidal attacks and chronic hemorrhoidal management, fast-acting micronized flavonoid formulations provide rapid relief from pain, swelling, and bleeding. Diosmin works synergistically with other citrus flavonoids to stabilize capillary membranes and reduce local inflammation.

Mechanisms of Action in Venous Circulation

Diosmin acts as a highly effective venotonic agent by prolonging the vasoconstrictor effect of noradrenaline on the venous wall. This increases venous tone and reduces venous capacitance, distensibility, and stasis. At the microcirculatory level, it decreases capillary hyperpermeability and reinforces capillary resistance, protecting the blood vessels from inflammatory cascades.

Clinical studies show that the integration of Micronized Purified Flavonoid Fraction (MPFF) significantly improves absorption rates. Micronization reduces the active particles to less than 2 microns, enhancing bioavailability and accelerating therapeutic onset for patients suffering from acute conditions.

Synergistic Flavonoid Formulations

The combination of Diosmin with Hesperidin, particularly in the optimized 90/10 ratio, demonstrates a superior therapeutic outcome compared to Diosmin alone. Hesperidin serves as the precursor and synergist, amplifying the anti-inflammatory and vascular-protective pathways. This biochemical synergy is key to modern clinical protocols for chronic venous insufficiency and lymphatic drainage disorders.

Key Active Ingredients Profile

SUSTAINABILITY OF ENTERPRISE

The innovation progress of Hawk Bio. is pushing us towards a more sustainable future. We are actively responding to the United Nations Sustainable Development Goals and Climate Action. By the end of June 2024, the plant had installed the first phase of solar photovoltaic panels with a power generation capacity of 200KW, which can meet 60% of the electricity demand of the whole factory. After the completion of the second phase of the project, solar power generation will meet all the electricity demand of the whole factory.

Our commitment to sustainability extends to green chemistry extraction methods, reducing waste, and minimizing our environmental impact while maintaining high-yield pharmaceutical outputs.

Green Manufacturing Goals

  • Clean Energy: 100% solar power target upon completion of Phase 2.
  • EcoVadis Bronze: Recognized international sustainability rating.
  • Resource Optimization: Advanced recycling of solvents used during citrus extraction.
  • Carbon Reduction: Actively cutting down baseline greenhouse gas emissions in raw material transportation and processing.
