Tazan is a combined preparation that stimulates the regeneration of cartilage tissue.
Release form and composition
The drug is produced in the form of film-coated tablets: biconvex, oval, film shell - from almost white to white; possible surface roughness (5 or 15 pieces in a blister strip or 30, 60 or 90 pieces in a polymer can, in a cardboard box instructions for the use of Tazan and 6, 12 or 18 blisters of 5 pieces, or 2, 4 or 6 packs of 15 pcs., or 1 can).
1 tablet contains:
- active ingredients: glucosamine sulfate sodium chloride (in terms of glucosamine sulfate) + chondroitin sodium sulfate - 250 mg + 250 mg / 500 mg + 500 mg;
- additional components: calcium stearate, colloidal silicon dioxide (aerosil), low molecular weight povidone (medical low molecular weight polyvinylpyrrolidone 12 600 + 2700), potato starch, crospovidone (Kollidon CL; additionally for a dose of 250 mg + 250 mg - Kollidon CL-M), tall ludipress (lactose monohydrate - 91–95%, povidone - 3–4%, crospovidone - 3–4%);
- film shell: propylene glycol, macrogol (polyethylene glycol 4000), hypromellose (hydroxypropyl methylcellulose), titanium dioxide.
Pharmacological properties
Pharmacodynamics
Tazan activates the process of cartilage tissue regeneration. The active substances of the drug are involved in the synthesis of connective tissue, helping to prevent the destruction of cartilage tissue and stimulating its regeneration. The use of exogenous glucosamine increases the production of cartilage matrix (chondrocytes and extracellular substance) and the degree of nonspecific protection against chemical damage to cartilage.
Glucosamine in the sulfate salt form is a precursor to hexosamine, and the sulfate anion plays an important role in the production of glycosaminoglycans. It is also assumed that glucosamine protects damaged cartilage from metabolic destruction caused by the use of non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticosteroids (GCS), and also has its own moderate anti-inflammatory effect.
Chondroitin sulfate, regardless of whether it is absorbed in intact form or as a group of individual components, acts as an additional substrate for the formation of a healthy cartilage matrix. The active ingredient stimulates the production of hyaluronone, proteoglycans and type II collagen, protects the matrix of cartilage tissue from enzymatic degradation (by inhibiting the activity of elastase and hyaluronidase) and from the destructive effects of free radicals, normalizes the viscosity of synovial fluid, stimulates the reparative processes of cartilage. When used for the treatment of osteoarthritis, the agent reduces the symptoms of the disease and reduces the need for NSAIDs.
Pharmacokinetics
Glucosamine
When taken orally, bioavailability is 25% (first pass effect through the liver). After distribution in tissues, the highest concentrations of the active substance are detected in the kidneys, liver and articular cartilage. Approximately 30% of the administered dose persists for a long time in muscle and bone tissues. The half-life (T 1/2) is 68 hours, the drug is excreted mainly by the kidneys unchanged, and some part - by the intestines.
Chondroitin sulfate
After oral administration of the drug at a single dose of 0.8 g (or 2 times a day at 0.4 g), the plasma level of chondroitin sulfate increases within 24 hours. In the form of low molecular weight and high molecular weight derivatives, approximately 20 and 10% of the administered dose are absorbed, respectively. The absolute bioavailability of the active substance is 12%, the apparent volume of distribution (V d) is about 0.44 ml / g. It is metabolized by desulfurization, excreted by the kidneys, T 1/2 - 310 min.
Indications for use
Tazan is recommended for use for the treatment of grade I – III osteoarthritis.
Contraindications
Absolute:
- severe renal impairment;
- age up to 15 years (for a dose of 250 mg + 250 mg) or up to 18 years (for a dose of 500 mg + 500 mg);
- pregnancy and lactation;
- hypersensitivity to any component of Tazan tablets.
Relative (use with caution):
- bronchial asthma;
- diabetes;
- tendency to bleeding;
- bleeding.

special instructions
In the event of adverse events from the digestive tract, it is recommended to reduce the dose of Tazan by 2 times, and if there is no improvement in the condition, to cancel the drug treatment.
If the clinical effect was not achieved after four weeks of taking Tazan in a daily dose of 8 tablets (250 mg + 250 mg) or 4 tablets (500 mg + 500 mg), it is necessary to decide on additional studies to clarify the diagnosis.

Reviews about Tazan
Reviews about Tazan found on specialized sites are rather contradictory. Some patients consider it an effective remedy for the treatment of osteoarthritis, because after a long course of treatment with the drug, the severity of the symptoms of the disease significantly decreased - the swelling and stiffness in the affected joints disappeared, pain and inflammation were stopped.
Another group of patients notes only a slight improvement in their condition or a complete absence of positive changes after a course of taking Tazan. Many indicate the development of side effects during therapy in the form of diarrhea, nausea, dizziness, insomnia and weakness. Sometimes they complain about the lack of the drug in pharmacies.
Price for Tazan in pharmacies
On average, the price of Tazan in the form of film-coated tablets (500 mg + 500 mg) is 1200 rubles. per package containing 90 pcs.
