Description Synvisc one 1 GENZYME 6 ml syringe

Synvisc one (Hylan GF 20) is a viscoelastic solution of hyaluronic acid recommended to relieve pain caused by osteoarthritis (a condition that causes "wear and tear" on the knee joint). Synvisc one (Hylan GF 20) has been shown to be effective when administered in all stages of joint disease. Supplementation with Synvisc one (Hylan GF 20) is a treatment that reduces pain and discomfort and thus increases the range of motion of the joint.

Description of Synvisc one

Synvisc one (Hylan GF 20) is a sterile, non-pyrogenic elastovisous fluid that contains hylans. Hylans are derivatives of hyaluronan (sodium hyaluronate) and are made up of repeating units of N-acetylglucosamine and sodium glucuronate. Synvisc one (Hylan GF 20) is biologically similar to hyaluronan. In vitro studies have shown that Synvisc one (Hylan GF 20) protects cartilage cells against certain physical and chilic lesions. Pain relief can last up to 6 months.

Directions for use of Synvisc one

Intra-articular route. Reserved for adults. The usual recommended dose is one injection into the knee joint. It is important that this medical device is used as directed by your doctor. Synvisc one (Hylan GF 20) should only be administered intraarticularly and by a doctor.

Composition of Synvisc one

Viscoelastic solution, hyaluronic acid. Each ml of sterile, pyrogen-free elastovis liquid contains 8 mg of hylan. Excipient with known effect: disodium hydrogen phosphate, sodium chloride, sodium dihydrogen phosphate monohydrate and water for injection.

Precautions for using Synvisc one

Keep out of reach of children. Never use Synvisc one (Hylan GF 20) if you are allergic to any of the constituents, if you have a skin condition at the injection site, if your joint is infected or inflamed.

Synvisc one overview

Box of 1 syringe of 6 ml.

Our advice from pharmacy experts

What is a joint made of ?
A healthy joint is made up of cartilage and synovial fluid, which protect the bones from impact and friction.
In an arthritis joint, the cartilage crumbles and the synovial fluid can no longer play its protective role. There is then a friction between the bones which causes pain, joint stiffness and swelling.
The injection of Synvisc-One replaces the arthritic synovial fluid with a natural substance forming a cushion which protects and lubricates the joint.
In the osteoarthritis knee, synovial fluid (also called "synovia") can leak out. When this happens, the knee loses its protective, lubricating pad.
Synvisc-One replaces arthritis synovial fluid to relieve pain and improve the ability of the joint to act as a natural shock absorber.

Presentation

Hylane GF 20 is available in two forms:

  • Synvisc, 2 ml: 2.25 ml glass syringe (boxes of 1 [ACL 34010 7848992 1 ] and 3 [ACL 34010 7647928 3 ]).

  • Synvisc-One, 6 ml: 10 ml glass syringe (ACL 34010 4864022 2 ).

Hylane GF 20 is a sterile, apyrogenic, viscoelastic liquid containing the hylane A and hylane B polymers produced from a highly purified avian extract. Hylans are derivatives of hyaluronan (sodium hyaluronate), and are composed of recurrent disaccharide units of N-acetylglucosamine and sodium glucuronate.

Hylane A has an average molecular weight of 6   000   000 daltons and hylane B is a hydrated gel. Hylane GF 20 contains hylan A and hylan B (8.0 mg ± 2.0 mg / ml) in buffered sodium chloride physiological solution (pH 7.2 ± 0.3).

Composition

For 1 ml (Hylane GF 20): hylane 8.0 mg, sodium chloride 8.5 mg, disodium phosphate 0.16 mg, sodium phosphate hydrate 0.04 mg, water for injections qs.

Synvisc contains 2 ml of Hylane GF 20. Synvisc-One contains 6 ml of Hylane GF 20.

properties

Hylane GF 20 is biologically similar to hyaluronan. Hyaluronan is a constituent of the synovial fluid which gives it its viscoelasticity. However, the mechanical (viscoelastic) properties of Hylane GF 20 are superior to those of the synovial fluid and hyaluronan solutions of similar concentrations. Hylane GF 20 has an elasticity (storage coefficient G ') at 2.5 Hz of 111 ± 13 pascals (Pa) and a viscosity (loss coefficient G' ') of 25 ± 2 Pa. The elasticity and viscosity of knee synovial fluid of subjects aged 18-27 years measured with a method comparable to 2.5 Hz are G '= 117 ± 13 Pa; G '' = 45 ± 8 Pa. Hylans are metabolized in the body by the same route as hyaluronan and the products of their degradation are not toxic.

indications

Hylane GF 20:

  • is a replacement agent and a temporary supplement for synovial fluid;

  • is effective when administered in all stages of joint disease;

  • is most effective when administered to patients whose regular physical activity mobilizes the affected joint;

  • exerts its therapeutic effects by acting as viscosupplement, restoring the physiological and rheological properties of the tissues of the joint affected by osteoarthritis.

The viscosupplementation with Hylane GF 20 is a treatment which reduces pain and discomfort and thus increases the range of motion of the joint. In vitro studies have demonstrated that Hylane GF protects cartilage cells against certain physical and chemical lesions.

Directions for Use, Dosage

Prior to injection, inform the patient that Synvisc and Synvisc-One are highly purified hyaluronic acid from an avian source.

Synvisc should only be administered intra-articularly and by a doctor to relieve the pain associated with osteoarthritis of the knee, hip, ankle and shoulder.

Synvisc-One should only be administered intra-articularly, and by a physician, to relieve the pain associated with osteoarthritis of the knee.

  • Do not use Hylane GF 20 if the packaging is opened or damaged.

  • The contents of the syringe must be used immediately after opening the package.

  • Aspiration of the synovial fluid or any effusion before each injection of Hylane GF 20.

  • Inject Synvisc at room temperature.

  • To remove the syringe from the thermoformed shell (or tray), grasp it by the body without touching the piston rod.

  • Inject Synvisc by applying strict aseptic methods and paying particular attention to the removal of the cap from the end of the syringe.

  • Unscrew the gray cap from the end of the syringe before removing it to minimize product leakage.

  • Use a suitable diameter needle:

    • Synvisc: 18 to 22 gauges;

      Use a needle of adequate length, depending on the joint to be treated.

    • Synvisc-One: 18 to 20 gauges.

  • To ensure a leak-tight connection and prevent leakage during administration, tighten the needle securely to the syringe's Luer clamp.

  • Do not tighten or apply excessive pressure to secure the needle or remove the sheath, otherwise the end of the syringe may be broken.

  • Inject only into the synovial space, performing the operation, if necessary, under fluoroscopic guidance, especially in the case of treatment of hip and shoulder joints.

  • The contents of the syringe are for single use only. As indicated in the dosage recommendations, inject the entire volume of the syringe (2 ml for Synvisc and 6 ml for Synvisc-One). Discard the entire Synvisc / Synvisc-One product not used remaining.

  • When working under radioscopic control, an ionic or non-ionic contrast agent may be used. Do not use more than 1 ml of contrast medium per 2 ml of Hylane GF 20.

  • Do not sterilize Hylane GF 20 again.

Dosage

The dosage of Hylane GF 20 depends on the joint to be treated.

Osteoarthritis of the knee:

Synvisc:

It is recommended to administer Synvisc in a dosage regimen of 3 injections of 2 ml in the knee, one week apart each. To achieve optimal effect, it is essential to administer the 3 injections. The maximum recommended dose is 6 injections over a 6-month period, with an interval of at least 4 weeks between treatment cycles.

Synvisc-One:

It is recommended to administer Synvisc-One according to a dosage regimen of a 6 ml injection into the knee. A second injection may be performed 6 months after the first injection, if the patient's symptoms warrant.

Osteoarthritis of the hip, ankle and shoulder:

Synvisc:

It is recommended that Synvisc be administered according to an initial dosage regimen of a single 2 ml injection. If, however, adequate symptomatic relief is not obtained after this injection, it is recommended to administer a second 2 ml injection. Clinical data showed that patients feel better the benefit of this second injection when administered between 1 and 3 months after the first injection.

Duration of Effects:

Treatment with Hylane GF 20 only affects the treated joint; there is no systemic effect.

Synvisc:

For patients who respond favorably to therapy, the duration of the therapeutic effect is generally 26 weeks maximum, although longer or shorter duration of efficacy has been observed. However, prospective clinical data revealed that patients with osteoarthritis of the knee had responded favorably to treatment up to 52 weeks after a single set of three injections of Synvisc.

Synvisc-One:

Prospective clinical trial data in patients with osteoarthritis of the knee showed a reduction in pain up to 52 weeks following a single injection of Synvisc-One, as well as a decrease in stiffness and improved functionality.

Clinical data from a randomized controlled double-blind trial in patients with osteoarthritis of the knee showed a statistically and clinically significant reduction in pain compared with placebo. A total of 253 patients were treated (124 received Synvisc-One and 129 received placebo). Over 26 weeks, patients receiving Synvisc-One had an average pain reduction percentage relative to baseline values ​​of 36%, while patients in the placebo group had an average percentage reduction in pain versus reference values ​​of 29%.

Other prospective clinical data from two open-label multicentre studies in patients with knee osteoarthritis showed statistically significant improvements in pain relief over baseline values ​​for up to 52 weeks administration of Synvisc-One.

In the first study, results obtained from 394 patients receiving Synvisc-One revealed a statistically significant change in the score obtained on the WOMAC A1 scale - walking pain scale - (28 ± 19.89 mm on a visual analog scale [EVA] of 100 mm) at week 26 compared to the reference values. In addition, statistically significant changes from the WOMAC A1 and WOMAC A, B and C scales were observed during the 6 observation periods between week 1 and week 52, confirming an improvement in the relief of (WOMAC A - 32.7 ± 19.95 mm; WOMAC A - 29.18 ± 19.158 mm); decreased stiffness (WOMAC B - 25.77 ± 22.047 mm); and an improvement in functionality (WOMAC C - 25.72 ± 19.449 mm) over 52 weeks.

In the second study, 571 patients receiving Synvisc-One showed a statistically significant improvement in pain over 26 weeks, as measured by the Verbal Pain Questionnaire (VPQ). The mean pain rating showed improvement in relief, with a baseline score of 3.20 during the baseline visit dropping to 2.24 at the 26-week visit, and 64.6% of patients reaching the pain relief. Secondary endpoints revealed statistically significant improvement in VPQ scores, regardless of the time points of observation, from week 1 to week 52, with mean VPQ scores decreasing by 3.20 at the baseline visit to 2.26 at the visit of week 52, and 61.5% of patients achieving pain relief.

Cons-indications

  • In the presence of venous or lymphatic stasis in the corresponding limb, Hylane GF 20 should not be injected into the joint.

  • Hylane GF 20 should not be injected into an infected or severely inflamed joint or in patients with a skin condition or infection at the injection site.

Precautions for use

Warnings   :

  • Do not inject intravascularly.

  • Do not inject outside the joint cavity or into the synovial tissue or capsule. Undesirable effects, usually at the injection site, were observed after extra articular injection of Synvisc.

  • Do not use concomitantly with disinfectants containing quaternary ammonium salts for the preparation of the skin as hyaluronan can precipitate in their presence.

Precautions:

  • Do not administer Hylane GF 20 in the presence of significant joint effusion before injection.

  • As with any invasive procedure in the joint, the patient is advised to avoid intense physical activity after intra-articular injection and to resume normal activities after a few days.

  • Hylane GF 20 has not been evaluated in pregnant women or children under 18 years of age.

  • Hylane GF 20 contains a small amount of avian proteins and should not be administered to people who are hypersensitive to these proteins.

Side effects :

  • Intra-articular injections of Hylane GF 20 may cause temporary pain, edema and / or effusion. Cases of acute inflammation characterized by articular pain, edema, effusion and sometimes a sensation of heat and / or stiffness in the joint have been reported following an intra-articular injection of Synvisc or Synvisc-One . Synovial fluid analysis revealed an aseptic liquid without crystals. This reaction often responds to treatment with non-steroidal anti-inflammatory drugs (NSAIDs), steroids administered intra-articularly and / or arthrocentesis in a few days. A therapeutic benefit is always possible after reactions of this type.

  • No cases of intra-articular infection occurred in clinical trials with Synvisc / Synvisc-One; a few cases have been reported following the commercialization of Synvisc.

  • Hypersensitivity reactions including anaphylactic reaction, anaphylactoid reaction, anaphylactic shock and angioedema have also been reported.

  • Rare systemic reactions reported after administration of Synvisc include: erythema, urticaria, itching, fever, nausea, headache, dizziness, chills, muscle cramps, paresthesia, peripheral edema, malaise, difficulty breathing, hot flushes and facial edema. The controlled clinical trials with Synvisc did not reveal any significant statistical differences in the number or types of adverse systemic effects between the group of patients treated with Synvisc and the control group.

  • In the controlled trial with Synvisc-One, the frequency and types of adverse events were similar in the group receiving Synvisc-One and the placebo group.

Storage conditions

The contents of each syringe are sterile and non-pyrogenic. Store between +   2   ° C and +   30   ° C. Do not freeze.

The place of homeopathy in the treatment of osteoarthritis The place of homeopathy in the treatment of osteoarthritis

Osteoarthritis is a degenerative disease of the joint characterized by destruction of the articular cartilage and marginal osteophytosis . Two forms of osteoarthritis are described: primary osteoarthritis and secondary osteoarthritis . In primary osteoarthritis, there is no clear or precise triggering cause. It mainly occurs in the subject over fifty years, presenting a predisposed ground. Secondary osteoarthritis follows a joint fracture, joint dysfunction of various causes (septic arthritis, malformation, etc.). It can be…
