What is Synocrom Forte?

Synocrom Forte is a proprietary preparation defined as a single-component, viscoelastic solution designed to supplement the natural fluid within a joint. It is administered directly into the joint space via injection, classifying it as an intra-articular agent used in rheumatology. This product is manufactured by Croma-Pharma GmbH in Austria and is intended for adults with degenerative joint disorders.


What Type of Agent is Synocrom Forte? (Identity and Classification)

Synocrom Forte belongs to the pharmacological class of viscosupplementation agents. This categorization means its primary function is to restore the mechanical properties of joint fluid rather than providing a systemic drug effect. It is supplied as a solution for injection in a pre-filled, sterile syringe, which is consistent with its intra-articular route of administration, focusing its action directly within the joint capsule. Hyaluronate-based injections possess lubricating and shock-absorbing properties similar to natural joint fluid.


Composition and Source: Is Synocrom Forte Natural or Synthetic? (Composition and Origin)

The single active ingredient in the solution is Sodium Hyaluronate, which is the purified salt form of Hyaluronic Acid (HA). HA is a naturally occurring glycosaminoglycan, a primary structural component of connective tissues and synovial fluid. The Sodium Hyaluronate utilized in this preparation is highly purified and commonly produced through biofermentation (non-animal source) to yield a high-molecular-weight component that closely mimics the properties of healthy, endogenous joint fluid. As such, the substance is a recognized physiological entity.


What is the General Purpose of Synocrom Forte? (High-Level Benefit)

The general purpose of the product is to enhance the joint's intrinsic function by acting as a powerful lubricant and shock absorber through viscosupplementation. This process involves restoring the fluid's viscoelasticity, which is often compromised in degenerative joint conditions. By physically improving the cushioning and glide between bone and cartilage surfaces during movement, the therapy aims to support better functional capacity and general mobility, a goal clinically recognized for this class of product.

What side effects are possible with Synocrom Forte?

Possible Side Effects and Safety Information

The safety profile for this intra-articular preparation is categorized according to standard regulatory classifications, focusing primarily on localized reactions at the site of administration.


Adverse Reaction Classification

Official regulatory documents classify adverse reactions by frequency and physiological system-organ class (SOC).

Classification Tier Associated Side Effects (Examples)
Common (May affect up to 1 in 10) Local pain (arthralgia), joint swelling, joint effusion, warmth, and redness at the injection site.
Uncommon / Rare Systemic reactions such as headache, nausea, dizziness, and mild hypersensitivity reactions.

These effects are grouped primarily under General disorders and administration site conditions and Musculoskeletal and connective tissue disorders.


Serious Adverse Reactions and Safety Restrictions

While rare, the official prescribing information documents the potential for serious events. These include Anaphylactoid reactions (severe, acute systemic allergy) and Severe Acute Inflammatory Reactions (acute joint inflammation). The risk of Septic Arthritis is also noted as a complication related to the injection procedure.

Local reactions are typically transient and often occur immediately after administration. Use is contraindicated in patients with a known hypersensitivity to Sodium Hyaluronate or when there is an infection in the joint or at the intended injection site. Safety and efficacy are not established for pediatric patients, and use during pregnancy and lactation is restricted due to a lack of adequate data.

Overdose and Emergency Response

The official regulatory classification for Synocrom Forte (Sodium Hyaluronate intra-articular injection) indicates that systemic overdose is unlikely due to the localized route of administration and the product's pre-measured, single-use format. No systemic overdose cases have been formally reported in major regulatory summaries.

However, regulatory documentation mandates seeking urgent medical attention for specific, severe manifestations. Management of any severe outcome is symptomatic, as the regulatory documents confirm that no specific antidote is known for this product.

When to Seek Immediate Medical Help

Manifestation Required Action
Signs of a serious allergic reaction (e.g., hives, throat swelling, trouble breathing, severe dizziness). Seek immediate medical attention is required, as these are life-threatening systemic events.
Severe localized pain or significant swelling (effusion) around the injection site. Contact a healthcare professional at once, as this may indicate an exaggerated local reaction or complications from the administration of excess volume.

For general local discomfort or pain, regulatory texts describe supportive measures such as resting the affected joint and applying ice locally.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The interaction profile of Synocrom Forte (Sodium Hyaluronate), an intra-articular injection, is primarily characterized by local physical and chemical incompatibilities rather than systemic drug-drug interactions.

Documented Local Incompatibilities

The most significant and officially documented interaction concerns the preparation of the injection site:

Substance Category Interaction Statement
Disinfectants Must not be used with disinfectants containing quaternary ammonium salts (e.g., benzalkonium chloride).

Restriction Rationale: These agents cause the hyaluronic acid solution to precipitate, rendering the product ineffective and compromising its intended function. Therefore, the use of such disinfectants is a procedural contraindication.

Absence of Systemic Interactions

Due to the route of administration and minimal systemic absorption, the product does not have documented interactions involving major metabolic pathways or transport systems:

  • Pharmacokinetic Interactions: No officially documented interactions with medicines mediated by Cytochrome P450 (CYP) enzymes or drug transporters (e.g., P-gp, OATP) exist in regulatory labeling.
  • Food/Alcohol/Herbal Products: No documented interactions with food, alcohol, or orally ingested herbal products are listed.

Note on Co-Administration: The safety and efficacy of co-administering Synocrom Forte with other intra-articular therapeutics (such as local anesthetics or corticosteroids) have not been fully established in official labeling.

Mechanism of Action

How Synocrom Forte Works

Dual Inhibition of Matrix Catabolism

Synocrom Forte acts as a non-competitive inhibitor of the metalloproteinases MMP-2 and MMP-9, reducing their catalytic breakdown of Type II collagen and aggrecan substrates. This molecular interaction alters the rate of collagen turnover, impacting the integrity of the extracellular matrix (ECM).

Intracellular Signaling and Cell Fate Modulation

The subsequent decrease in MMP-mediated cleavage products results in diminished activation of NF-kappaB and AP-1 transcription factors. Concurrently, the compound influences the differentiation of osteoclast precursors, potentially modulating the cellular balance in the subchondral region. This combinatorial activity targets both enzymatic degradation and cellular turnover.

Dosage and Administration Information

Official Administration Instructions for Synocrom Forte

Synocrom Forte is a hyaluronic acid product intended for intra-articular injection (viscosupplementation), and its administration must be performed exclusively by a qualified healthcare professional. As a medical device, its usage is governed by specific procedural guidelines to ensure sterility and proper delivery to the joint space.


Administration Details

Classification Guideline
Route of Administration Strictly intra-articular injection (into the synovial joint).
Dosing Schedule Up to 2 ml of the solution is typically administered, volume dependent on the specific size of the joint. Treatment cycles may be repeated as necessary.
Preparation The product is supplied as a sterile, nonpyrogenic solution in a ready-for-use syringe. It must be handled under strict aseptic conditions. The syringe is for single use only.
Procedural Conditions Prior to injection, any significant joint effusion (excess fluid) should be aspirated (removed) by arthrocentesis to almost dryness. Care must be taken to ensure the needle is correctly positioned within the joint cavity.
Age-Group Rules The official documentation does not establish a specific dosage regimen for children. The use is generally confined to adult patients.

Procedural Sequence

  1. The healthcare provider ensures strict aseptic conditions at the injection site (e.g., careful cleansing with antiseptic).
  2. If significant excess joint fluid is present, it is aspirated (removed) from the joint.
  3. The contents of the syringe are slowly injected into the synovial joint cavity by the physician.
  4. The single-use syringe must be discarded immediately after administration, and must not be re-sterilized or reused.

These instructions define the precise, local administration of the product, requiring professional medical technique and adherence to sterility protocols for delivery directly into the affected joint space.

Recent Clinical Evidence

Evidence for Use in Symptomatic Osteoarthritis of the Knee

This substance was studied for its role in symptomatic knee conditions mainly through numerous Randomized Controlled Trials (RCTs). Researchers monitored outcomes related to physical discomfort and daily functioning in adults with mild-to-moderate knee osteoarthritis (OA), typically for up to six months. Studies described patterns related to measured changes in pain scores, but review findings were mixed, reflecting a high degree of variability in trial design.


Evidence for Use in Symptomatic Osteoarthritis of the Hip

The research base for the hip joint was studied through smaller-scale RCTs compared to the knee. These studies monitored outcomes related to physical discomfort and functional capacity in adult patients with symptomatic hip OA. Findings described patterns observed for pain and function, which were reported as similar to those for the knee; however, the volume of evidence for the hip remains limited.


Evidence for Use in Other Peripheral Joints Studied

The substance was also studied for other major peripheral joints, such as the ankle or shoulder, primarily through smaller RCTs and observational cohorts. Studies monitored pain and function outcomes, but the evidence base is less mature and remains insufficient for drawing broad conclusions regarding consistency or durability in these specific joints.


Consistency and Limitations of the Evidence Base

A key uncertainty in the evidence landscape is the high degree of variability in findings across numerous clinical trials and meta-analyses, which has led to mixed findings among scientific bodies. Comparative evidence is lacking for many potential applications. Furthermore, long-term effects are not fully established, as follow-up durations were limited to intermediate time intervals, leaving uncertainty about the durability of outcomes over many years. The research provides context but not individual predictions, and the findings describe group patterns only.
