What Type of Medicine Is Synoart and What is its Composition?

Synoart is a specialized, single-ingredient product classified as a viscosupplement, delivered as a sterile solution for intra-articular injection. Products in this category, which contain Sodium Hyaluronate, are characterized by a primary action that is physical or mechanical. The product's active core is Sodium Hyaluronate (the sodium salt of Hyaluronic Acid), which is categorized as a drug for disorders of the musculo-skeletal system. Sodium Hyaluronate products are recognized for their role in managing joint mechanical function.

The active substance, Sodium Hyaluronate or Hyaluronan, is a high-molecular-weight glycosaminoglycan—a polysaccharide structurally identical to a substance found naturally in the body’s synovial fluid and cartilage. Although Hyaluronan is natural to the body, the pharmaceutical-grade substance utilized in products like Synoart is highly purified and typically manufactured in a controlled environment, often via a bacterial fermentation process, to ensure a nonpyrogenic and consistent product for injection.


What is the General Purpose of Sodium Hyaluronate in Joints?

The general purpose of Synoart is to restore the essential viscoelastic property of the fluid within a compromised joint. It acts physically to supplement the reduced and degraded native joint fluid, allowing the product to function as both an effective internal lubricant and a shock absorber within the joint space.

This mechanical support helps mitigate the friction and internal irritation that contribute to discomfort and stiffness during movement. The application of this purified Hyaluronan is designed to contribute to improved joint comfort and the overall maintenance of mobility, a typical use scenario being the temporary relief of pain in large weight-bearing joints. The action is primarily mechanical, aiming to stabilize the joint environment rather than addressing systemic inflammation.

What side effects are possible with Synoart?

Possible Side Effects and Safety Information

Adverse reactions associated with sodium hyaluronate viscosupplements, such as Synoart, are officially classified by their frequency and the body system affected, based on clinical trial data reported in government regulatory documents.

Documented Adverse Reactions

The most frequent reactions are typically localized and transient. The official regulatory labeling classifies these effects by System-Organ Class (SOC):

Classification Typical Reactions (by SOC)
Very Common (ge 10%) Musculoskeletal Disorders: Arthralgia (joint pain).
Common (1% to 10%) Administration Site: Injection site pain, swelling, warmth, redness, joint effusion. Systemic: Headache, dizziness, nausea, back pain.

Injection site reactions are commonly documented as transient, typically resolving spontaneously within 48 hours of administration. Uncommon reactions may include gastrointestinal complaints (diarrhea, dyspepsia) and infections (e.g., urinary tract infection).


Serious Adverse Reactions and Safety Constraints

Serious Adverse Reactions officially listed are rare but clinically significant and include Anaphylaxis (a severe systemic allergic reaction) and Joint Infection (Septic Arthritis), which is a risk associated with any intra-articular injection procedure.

Safety-Related Restrictions preclude the use of this product in patients with known hypersensitivity to hyaluronate preparations or in those with infections or skin diseases in the area of the injection site. Use in patients on anticoagulant therapy may also be associated with an increased risk of bleeding at the injection site.

Population-Specific Safety: The official safety and effectiveness of this medicine have not been established for pediatric use or for use in pregnant or lactating women, and its use is typically restricted to adults.

Overdose and Emergency Response

Overdose and When to Seek Help

The regulatory profile for Synoart, as an intra-articular viscosupplement, does not classify a classical dose-dependent systemic overdose syndrome. Instead, the focus is on documented severe local reactions and potentially life-threatening systemic events that necessitate mandated emergency action.

Documented Manifestations

Over-reaction or severe adverse events may be indicated by intense joint pain (Arthralgia), significant joint swelling (Effusion), and pronounced joint warmth at the injection site. Systemic manifestations, which signal severe outcomes, include widespread hives (Urticaria), rash, fever, transient hypotension, or rare instances of anaphylactic reaction and angioedema. These serious events are documented to affect the immune, respiratory, and cardiovascular systems.

Emergency Actions Required

Official labeling requires distinct actions based on the severity of the reaction:

  • Seek immediate medical help if signs of a systemic allergic reaction occur, such as difficult breathing or swelling of the face, lips, or throat.
  • Call a healthcare professional at once if experiencing severe pain or swelling in the injected joint.

No specific antidote is known for Synoart. Management is uniformly defined as symptomatic and supportive treatment, which may include procedural intervention like removal of excess joint fluid (arthrocentesis) for severe local reactions. No population-specific overdose considerations are established in regulatory documents for hepatic or renal impairment.

Therapeutic Uses of Synoart

Main Uses and Therapeutic Intent

Synoart is a viscoelastic supplement designed to manage symptoms associated with joint degeneration. It is primarily used to address discomfort and restricted mobility in synovial joints, most commonly the knee. The treatment is intended for patients who experience persistent joint pain that has not responded sufficiently to conservative non-pharmacological therapies or simple analgesics.

The primary therapeutic goal is to supplement the synovial fluid within the joint capsule. In healthy joints, synovial fluid acts as a lubricant and a shock absorber. In conditions such as osteoarthritis, the quality of this fluid diminishes, leading to increased friction and mechanical stress on the cartilage. Synoart aims to restore the rheological properties of the joint environment.

Benefits and Physiological Impact

Improved Lubrication and Shock Absorption

By introducing high-molecular-weight sodium hyaluronate into the joint space, Synoart helps normalize the viscosity of the synovial fluid. This improved lubrication reduces the mechanical friction between the articular surfaces during movement.

Pain Reduction

Many patients experience a decrease in chronic joint pain following the administration of Synoart. This effect is attributed to the protective coating the substance provides over the sensory receptors of the synovial membrane, as well as the reduction of mechanical irritation within the joint.

Enhancement of Mobility

As a result of decreased pain and improved mechanical function, Synoart can help restore a greater range of motion. This allows individuals to engage more comfortably in daily physical activities and may contribute to a better overall quality of life regarding joint health.

Protection of Articular Tissues

While the treatment is symptomatic, the restoration of a stable viscoelastic environment may help protect the remaining cartilage from the accelerated wear caused by inadequate lubrication. It serves as a temporary physical buffer against the stresses of weight-bearing and repetitive motion.

Eligibility and Restrictions for Use

Eligibility Map: Who can and cannot use Synoart — official regulatory information

This section describes the official eligibility and non-eligibility information for Synoart, strictly based on governmental regulatory documents.


Populations for Whom Use is Prohibited or Restricted

Contraindicated: You must not use this medicine if you have a known hypersensitivity or allergy to hyaluronate preparations (hyaluronic acid products) or to gram-positive bacterial proteins. The injection is also strictly contraindicated if the knee joint is infected or if there is skin disease or infection at the intended injection site.

Special Consideration/Not Recommended: Use is generally not recommended for patients with active inflammatory arthritis or an acute exacerbation of osteoarthritis. If the joint has significant fluid accumulation (effusion), this condition should be treated and resolved before receiving the injection.

Age and Physiological States: Safety and effectiveness have not been established for the pediatric population. Additionally, use is not established for pregnant women or women who are nursing (lactation). This lack of established data restricts use in these groups.


Summary of Eligibility Profile

Official regulatory documents define strict eligibility based primarily on the local condition of the target joint and the potential for allergic reactions. Absolute prohibitions apply when there is an infection risk from the injection procedure or a known allergy to the product’s components. For pediatric, pregnant, and lactating populations, the medicine is restricted because official regulatory safety and efficacy profiles have not been formally established.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory information regarding Synoart, an intra-articular viscosupplement, indicates that its interaction profile is predominantly local, which is consistent with its route of administration into the joint space. This local action means that systemic drug interactions are not typically documented in prescribing information.

Local Chemical Incompatibility

The most significant and formally documented interaction is a local chemical incompatibility. Contact with solutions containing Quaternary Ammonium Salts (QAS) is strictly prohibited during the injection procedure. Substances in this category, which include disinfectants such as Benzalkonium Chloride, must be avoided because they may cause the precipitation of the Sodium Hyaluronate product.

Interaction Scope Regulatory Status
Systemic Drug-Drug Interactions None documented
Metabolic Interactions (e.g., CYP) None documented
Food, Alcohol, or Herbal Products None documented
Local Chemical Interaction Officially documented restriction: Avoid QAS

Other Co-Administration Considerations

Regulatory labeling generally confirms that the safety and effectiveness of co-administering this product concurrently with other intra-articular injectables—such as local anesthetics or corticosteroids—have not been established. Due to the minimal systemic absorption, the official prescribing information does not list restrictions or necessary adjustments for orally administered medicines.

Mechanism of Action

Viscoelastic Action and Neurosensory Pathway Modulation

The immediate primary mechanism is viscosupplementation, where the high-molecular-weight polymer physically increases the viscoelasticity of the synovial fluid. This action alters the rheology of the fluid, resulting in decreased frictional forces between articular surfaces. Concurrently, the viscous solution forms a barrier layer over the articular nociceptor terminals, mechanically stabilizing the tissue and dampening their sensitivity, thereby reducing the afferent nerve impulse generation in response to mechanical stimulation.

Cellular Modulation and Catabolic Cascade Regulation

Beyond physical action, the molecule binds to receptors such as CD44 on chondrocytes and synoviocytes. This binding modulates intracellular signaling, initiating an anabolic and catabolic regulation cascade. This involves reducing the synthesis of matrix-degrading enzymes (MMPs and ADAMTS) and pro-inflammatory mediators (e.g., IL-1beta), while stimulating anabolic processes associated with the synthesis of joint matrix components. This mechanism influences the balance of Extracellular Matrix (ECM) turnover and promotes a localized anti-inflammatory state.

Dosage and Administration Information

Synoart is a food supplement typically presented in tablet form and is intended for oral administration. It is a commercially available formulation containing substances such as hyaluronic acid and unmodified collagen type II.

Administration and Dosage

The recommended dosage for adults is generally one 1500 mg tablet per day taken orally. The tablet should be swallowed whole with water.

Patients should adhere to the daily dosage specified by their healthcare provider or as indicated on the product's official labeling. Individuals are advised to consult their healthcare professional prior to starting any new supplement regimen to ensure it is appropriate for their specific health needs and to avoid potential interactions with other medications or supplements.

Patient Group Recommended Daily Dose
Adults One 1500 mg tablet

Important Considerations

  • Consistency: For consistent absorption, it is advisable to take the supplement at approximately the same time each day.
  • Missed Dose: In the event of a missed dose, the next scheduled dose should be taken at the regular time. Do not double the dose to compensate for the one missed.
