Compositron^® can be administered and applied only by medical specialists.
Field of application: orthopedics, rheumatology, traumatology, neurology, cosmetic medicine.

Compositron^® is a medical device for strengthening and replenishing the microstructures of the extracellular matrix of connective tissue and for collagen-supplementation of synovial fluid. It can be recommended for improving joint mobility, maintaining connective tissue structures of muscles, tendons, ligaments and menisci in degenerative processes caused by aging, injuries, increased loads and postural disorders. It can also be used in joint surgery to accelerate functional recovery and improve the condition of patients in a postoperative period as well as to counteract physiological aging and / or degeneration of connective and cartilage tissues.
Hydrolyzed collagen can replenish and strengthen the collagen matrix of tissues damaged by natural aging processes, degenerative and inflammatory pathologies, traumatic effects. The clinical effects of the injection of exogenous collagen come true to the mechanical action to restore the natural structure and functional properties of connective tissue, strengthen the muscle-tendon and capsule-ligamentous apparatus, which for example can improve joint mobility, restore the elasticity of the extracellular matrix and reduce (indirect effect) pain symptoms.
Reinforcement of the extracellular matrix and connective tissue microstructures in case of intradermal injection allows to replenish and to strengthen a skin collagen matrix, damaged during natural aging and traumatic effects.

Read the instructions before use.
Compositron^® is a medical device of risk class 3 intended for individual and single use. The product cannot be reused or re-sterilized. The product must be used by qualified personnel under aseptic conditions. Compositron^® can be used for patients treated with injectable forms of hyaluronic acid; PRP (PRP-platelet-rich plasma) or other autogenic cell concentrates.
It is necessary to limit physical activity after the implantation for several hours. Physical exercises are prohibited for 24 hours.
In case of using Compositron^® by patients with intra-articular effusion, the exudate must be removed before an implantation.
If the package is opened or damaged do not use Compositron^®. Perform an implantation immediately after opening the sterile package.
Do not inject Compositron^® intravascularly.
Do not use Compositron^® after the expiration date. The shelf life of the product is valid only for product stored in accordance with the claimed storage conditions in undamaged packaging.
Keep out of reach of children.

The implantable collagen devices are compatible to use in magnetic resonance investigations in magnetic fields induction at least up to 3 Tesla. Radiation, electromagnetic and magnetic fields do not affect directly on Compositron^® and its properties do not trigger as well any known relevant subsequent effects in a human body.
Compositron^® is not able to be visualized through radiological, ultrasound and other scanning procedures due to the proximity of their physical properties to the natural components of human tissues.

• allergy to bovine collagen and / or vitamin C;
• infections of joints and periarticular tissues at the implantation site;
• erythema, psoriasis at the implantation site;
• hemarthrosis of the joint to be treated.

No side effects have been reported as a result of the use of Compositron^®. However, the occurrence of local temporary inflammatory symptoms (pain, fever, redness and swelling, the increase of a content of an exudate in a joint cavity) are not excluded. After intra-articular injection reversible local reactions may occur such as short-term restriction of mobility (stiffness), a feeling of discomfort or heaviness in the joint and hematomas. These symptoms can be reduced by applying ice to the injection site for 5-10 minutes.
The symptoms of allergic reactions to collagen (for example itching, rash, hives) and anaphylactic reactions, septic arthritis, interstitial bleeding or hemorrhage in a joint cavity, tendonitis, phlebitis, paresthesia, dizziness, headaches, muscle spasms, a feeling of heat, a general sense of malaise, peripheral edema can occur.
It is necessary to consult with doctor in case of appearance of local or general symptoms.

Compositron^® is intended for use in medical institutions in aseptic conditions of manipulation and treatment rooms. Intra-articular, periarticular, intramuscular, intradermal and subcutaneous implantations are possible.
The product is released ready for use. Remove the protective cap before implantation, connect the Compositron^® syringe with a sterile needle of the desired size in accordance with the type of manipulation required (recommended needle size 20 – 30 G, not included) and to implant under aseptic conditions. Local anesthetic may be recommended for access to deep or painful areas.
The volume of intra-articular implantation depends on the size of the target joint.
Treatment protocols:
 Compositron^® 5 mg / ml
- single intra-articular, intramuscular, subcutaneous implantation or implantation into tendon-ligamentous structures.
The treatment regimen should be adjusted according to the personal features of patients.


• Intradermal and subcutaneous microimplantation technique: insert a needle (suggested size, 30G) to a depth of 1-3 mm and to implant 0.2-0.3 ml into the affected tissue.
• Intramuscular implantation technique: insert a needle (suggested size, 26-28G) into the muscle to a depth from 2 mm to 50 mm depending on the application area and to implant 0.3-0.5 ml.
• Periarticular implantation technique: insert the needle (suggested size, 26-28G) perpendicular to a skin surface to a depth of 2-8 mm (depending on the joint) and perform an implantation of 0.3-0.5 ml.
• Intra-articular implantation technique: follow generally accepted clinical guidelines for a specific joint. Implant 0.1-4.0 ml depending on the volume of the affected joint (suggested needle size, 23-28G).

In the case of severe reactions, the removal of Compositron^® from the joint cavity can be recommended, including lavage in accordance with the current clinical guidelines.
If the reaction to Compositron^® was not associated with the individual intolerance to the components of the product, it is possible to inject the device in 3 weeks after an inflammation subsides.
