Tendosun Uses, Dosage, Side Effects, Food Interaction and all others data.

Chondroitin sulfate is a glycosaminoglycan considered as a symptomatic slow-acting drug for osteoarthritis (SYSADOA). The SYSADOA status suggested a pain relief and increased joint mobility after a relative long regular administration, as well as a long-lasting effect after the end of the treatment. Chondroitin sulfate is composed of alternating 1,3-N-acetyl-β-d-galactosamine and 1,4-β-d-glucuronic acid units which bear 4-O- and/or 6-O-sulfations at the N-acetylgalactosamine units disposed of in specific patterns. Depending on the predominating disaccharide unit, it will present different biological activities. Chondroitin sulfate is sold as an OTC dietary supplement in North America and it is a prescription drug under the EMA in Europe.

In clinical trials, chondroitin sulfate has been reported a significant pain relief. Some reports have shown no slow in joint damage. The effects of chondroitin sulfate have been very controversial. One of the characteristics of chondroitin is a slow onset of action with a maximal effect attained after several months. Chondroitin sulfate has been reported to have anti-inflammatory properties by reducing the synovitis and prevent proinflammatory cytokine up-regulation in arthritis models.

It is also registered an anabolic effect of chondroitin sulfate in which it induces the synthesis of hyaluronate in synovial cells, it increases type II collagen and proteoglycan synthesis.

Sodium hyaluronate is a polysaccharide which functions as a tissue lubricant. It is widely used in ophthalmic surgery because it forms a viscoelastic solution in water which makes it a suitable substitute for aqueous and vitreous humour.

Uses

Chondroitin sulfate, used with glucosamine, is indicated to alleviate pain and inflammation from primary osteoarthritis. This supplement is reported to improve joint function and slow disease progression. Osteoarthritis is characterized by progressive structural and metabolic changes in joint tissues, mainly cartilage degradation, subchondral bone sclerosis and inflammation of synovial membrane.

Studies have proposed the potential use of chondroitin sulfate as a nutraceutical in dietary supplements.

Sodium Hyaluronate is used for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative nonpharmacologic therapy, and to simple analgesics, e.g., acetaminophen.

Sodium Hyaluronate is a viscous solution consisting of a high molecular weight fraction of purified natural sodium hyaluronate in buffered physiological sodium phosphate. It has a pH of 5.5-7.0. Hyaluronic acid is an important component of the body's extracellular matrix and is present in a particularly high concentration in cartilage and synovial fluid. Endogenous hyaluronic acid provides viscosity and elasticity to synovial fluid, which is fundamental for its lubricating and shock absorbing properties. It is essential for the correct structure of proteoglycans in articular cartilage. In osteoarthritis there is an insufficient amount of and a chance in the quality of hyaluronic acid in synovial fluid and cartilage. The intra-articular administration of hyaluronic acid into arthritic joints with degenerating cartilage surfaces and pathologically altered synovial fluid improved functions.

Tendosun is also used to associated treatment for these conditions: Arthritis, Backache, Muscle Strain, Osteoarthritis (OA), Soreness, Muscle, Sprains, Eye lubrication, Joint supplementation

How Tendosun works

Chondroitin sulfate functions as a major component of the intricate extracellular matrix. It is proposed that chondroitin sulfate supply can provide new building blocks for the synthesis of new matrix components.

The anti-inflammatory effect of chondroitin sulfate is thought to be caused by the inhibition of the synthesis of inflammatory intermediates such as the inhibition of nitric oxide synthase, COX-2, microsomal prostaglandin synthase 1 and prostaglandin E2. It is reported also an inhibitory activity in the toll-like receptor 4 which will later inhibit inflammatory cytokines, NFkB and MyD88. This activity suggests a modulation of the MAP kinase pathway. On the other hand, some reports have pointed out an induction on the PKC/PI3K/Akt pathway in neuroblastoma.

The anabolic effect of chondroitin sulfate is suggested to be caused by the inhibition of metalloproteinases such as MMP-1, -3 and -13 as well as ADAMTS-4 and -5.

Dosage

Tendosun dosage

Sodium Hyaluronate is administered by intra-articular injection. A treatment cycle consists of five injections given at weekly intervals. Some patients may experience benefit with three injections given at weekly intervals. Inject the full 2 ml in one knee only. If treatment is bilateral, a separate injection should be used for each knee.

Side Effects

The common side-effects include gastrointestinal complaints, injection site pain, knee swelling/effusion, local skin reactions (rash, ecchymosis), pruritus, and headache.

Toxicity

Chondroitin sulfate does not present a carcinogenic potential. On tolerability assays, it has been shown to present great safety and good tolerability without significant severe side effects.

Precaution

Use caution when injecting Sodium Hyaluronate into patients who are allergic to avian proteins, feathers, and egg products. Strict aseptic administration technique must be followed. Remove joint effusion, if present, before injecting Sodium Hyaluronate. Do not use the same syringe for removing joint effusion and for injecting Sodium Hyaluronate. It is recommended that the patient avoid any strenuous activities or prolonged (i.e., more than 1 hour) weight-bearing activities such as jogging or tennis within 48 hours following the intra-articular injection.

Volume of Distribution

After intramuscular administration of chondroitin sulfate, the apparent volume of distribution was 0.40 ml/g. When administered orally, the apparent volume of distribution changed to 0.44ml/g.

Elimination Route

Chondroitin sulfate is absorbed from the gastrointestinal tract. The absorbed portion reaches a ratio of 10% as unchanged chondroitin sulfate and 90% as depolymerized low-molecular-weight derivatives. This absorption depends on the sulfation status. The bioavailability of chondroitin sulfate ranges from 10-20% following oral administration. Reports have shown a consistent accumulation of the compound in joint tissue. The steady-state is attained after 3-4 days and it takes around 3-6 months to obtain the maximal effect.

After intramuscular administration of chondroitin sulfate, the peak plasma level of 3.8 mcg/ml was reached after 90 min. When given orally, the peak plasma concentration of 4.6 mcg/ml was reached after 240 min.

Half Life

The approximate half-life of chondroitin sulfate and its derivative metabolites is 15 hours. After intramuscular administration of chondroitin sulfate in humans, the elimination half-life of the chondroitin sulfate was of 275 min. When administered orally, the elimination half-life was presented at 310 min.

Elimination Route

Chondroitin sulfate is excreted in the urine as intact polymers and as partial degradation products. After intramuscular administration, about 37% of the administered dose is excreted by urine during the first 24 hours as high- and low-molecular-weight derivatives.

Pregnancy & Breastfeeding use

The safety and effectiveness of Sodium Hyaluronate have not been established in pregnant women. It is not known if Sodium Hyaluronate is excreted in human milk. The safety and effectiveness of Sodium Hyaluronate have not been established in lactating mother. The safety and effectiveness of Sodium Hyaluronate have not been demonstrated in children.

Contraindication

The drug is contraindicated in patients with known hypersensitivity to hyaluronate preparations. Intra-articular injections are contraindicated in cases of past and present infections or skin diseases in the area of the injection site.
