Hyaluronate derivatives, often referred to as hyaluronic acid derivatives, are modified forms of hyaluronic acid (HA). Hyaluronic acid is a natural substance found in the human body and is known for its ability to retain water, which contributes to the skin's hydration and elasticity. In the context of derivatives, modifications are made to the hyaluronic acid molecule to enhance its properties for various applications, particularly in the fields of medicine, cosmetics, and pharmaceuticals.

Hyaluronate and derivatives (available as Juvederm and other brands) are widely distributed in the extracellular matrix. They are used as an intraarticular injection for osteoarthritis, intradermally for wrinkles, and for cheek augmentation.

• It's crucial for the surgeon to determine the appropriate amount based on the nature of the eye procedure being performed.
• This ensures the best possible outcome and safety for the patient.

Use in Children:

Not indicated.

Pregnancy Risk Category: C

• In studies with animals, no harmful effects were seen during pregnancy.
• However, it's not clear if it's safe for pregnant women since specific research on this hasn't been done yet.
• More studies are needed to understand if there are any risks or if it's safe for pregnant women to use.

Use during breastfeeding:

• It's uncertain whether hyaluronic acid derivatives are present in breast milk.
• Manufacturers advise caution when giving these derivatives to breastfeeding women.
• This means that there's not enough information to confirm whether these substances pass into breast milk or if they could affect a nursing baby.

Dose in Kidney Disease:

• The information from the manufacturer's labeling indicates that there are no recommended changes in dosage for individuals with renal impairment.
• This means that, according to the manufacturer's instructions, the usual dosage of the product should be followed regardless of any kidney-related issues.

Dose in Liver disease:

• The manufacturer's labeling indicates that there are no recommended changes or dosage adjustments for individuals with hepatic (liver) impairment.
• This suggests that, according to the manufacturer's instructions, the usual dosage of the product should be followed regardless of any liver-related issues.

Depending on the formulation and the application or injection site, local reactions can take different forms. Lidocaine is mentioned concurrently in some reports.

Contraindications to Hyaluronate (Juvederm):

• If someone has a strong reaction or allergy to hyaluronate or any part of the product, they should avoid using it. This is known as hypersensitivity.

Submucosal and Intradermal:

• For injections under the skin or in certain tissues, there are some situations where it's not recommended.
• These include a history of severe allergic reactions or anaphylaxis, the presence of multiple severe allergies, bleeding disorders, a history of strong sensitivity to certain bacterial proteins or specific local anesthetics.
• Additionally, it's important to follow the recommended injection sites as per the product instructions.

Intraocular:

• The manufacturer's instructions for intraocular use, involving products like Amvisc, Amvisc Plus, Biolon, Healon (all formulations), and Provisc, do not list any specific situations where the use of these products is not recommended.
• This means that, according to the manufacturer's information, there are no contraindications or reasons why these products cannot be used in the eye for specific procedures.

Intra-articular

• For injections directly into the knee joint, there are certain situations where it's not recommended.
• This includes having an infection in the knee joint, infections or skin diseases at the injection site, hypersensitivity to specific bacterial proteins, and systemic bleeding disorders.

Subcutaneous/Supraperiosteal:

• Numerous severe allergies and a history of anaphylaxis are further contraindications (Juvederm Voluma XC and Restylane Lyft).
• Patients with a history of reactions to proteins from gram-positive bacteria or lidocaine (Juvederm Voluma XC and Restylane Lyft).

Monitoring parameters:

Intraocular Formulations (Eye Use):

• Keep an eye out for changes in intraocular pressure (pressure inside the eye) when using formulations for the eyes.
• Report any unusual symptoms or discomfort to your eye doctor.

Intradermal Formulations (Under the Skin):

• Watch for signs of too much local inflammation or infection at the injection site.
• If you notice any redness, swelling, or other unusual symptoms, let your healthcare provider know promptly.

How to administer Hyaluronate?

Intra-articular:

• Inject directly into the knee joint; avoid injecting outside the joint or into specific tissues.
• Do not use certain disinfectants for skin cleaning before the injection.
• If treating both knees, use separate syringes for each.
• Follow the manufacturer's instructions for injection technique.

Intradermal/Submucosal/Subcutaneous/Supraperiosteal:

• Avoid injecting into blood vessels.
• Massage the area after injection.
• Apply an ice pack if the treated area is swollen.
• Before treatment, avoid certain medications and supplements to reduce the risk of bruising and bleeding.
• Follow the specific injection guidelines for each product.

Ophthalmic:

• Let the product reach room temperature before using.
• If the drug looks cloudy or forms a slight precipitate after administration, it can be removed by irrigation or aspiration.
• Refer to the manufacturer's instructions for procedure-specific details.

Topical (Bionect products):

• Clean and disinfect the wound before applying.
• Avoid certain disinfectants due to the potential for hyaluronic acid precipitation.
• Apply a thin layer without rubbing extensively.
• Cover the area with sterile gauze and, if needed, a compressive bandage.

Topical (Therapevo):

• For wound or ulcer management, clean with normal saline and debride if necessary.
• Apply liberally to the ulcer or wound and surrounding area.
• Cover with non-stick gauze dressing after application.
• For dermatoses, apply directly and liberally to the affected area.

Mechanism of action of Hyaluronate (Juvederm):

• Sodium hyaluronate is a natural substance found throughout the body, especially in connective tissues like the vitreous and aqueous humor of the eyes, synovial fluid, skin, and umbilical cord.
• It creates a solution that acts like a gel in water, making it useful in surgeries involving the eyes and joints.
• Sodium hyaluronate helps lubricate tissues and joints, playing a crucial role in how tissues interact.
• When injected into the skin, it can reduce the depth of facial wrinkles.
• For lip augmentation, injecting it just under the skin's surface can help smooth out wrinkles around the mouth.
• In cheek augmentation, injecting it below the skin's surface can address age-related volume loss.
• In topical applications for wound and ulcer care, sodium hyaluronate provides a protective layer, shielding the skin from friction and abrasion.

Distribution:

• Intravitreous Injection:
  • Diffusion of sodium hyaluronate happens gradually when injected into the vitreous (the jelly-like substance in the eye).

Excretion:

• Ophthalmic:
  • Excretion of sodium hyaluronate occurs through the Canal of Schlemm, a drainage system in the eye. This is the route through which the substance leaves the eye after being used in ophthalmic procedures.
