The representation of pain syndromes of various localization is very extensive: in the knee and hip joints, this figure reaches 57,8% of the general population, in the shoulder joint 48–84%, and pain in the lower back is experienced by up to 85%. The prevalence of osteoarthritis (OA) increases with age. OA occupies a leading position among all rheumatological diseases, accounting for more than 60–70 % of their total number, and is the leading cause of chronic pain syndrome in the older age group. Clinical symptoms of OA are observed in 30–50% of the population in people over 65 years. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most commonly used drugs for the treatment of pain syndromes. NSAIDs are characterized by a good analgesic effect, but are often the cause of the development of adverse events (NSAIDS). Alternative for the treatment of degenerative-dystrophic lesions of the joints is chondroprotectors (CP). CPS belong to the group of drugs of delayed action of symptomatic therapy (SYSADOA). Among CP, chondroitin sulfate (CS) is considered to be the most acceptable means that can affect metabolic processes in cartilage, synovial and bone tissue, suppressing the synthesis of proinflammatory mediators. The main effects that CS has on the joint in OA are: anti-inflammatory, analgesic, and protective. CS improves the phosphorus-calcium metabolism in cartilage, inhibits enzymes that violate the structure and function of articular cartilage, inhibits the degeneration of cartilage; stimulates the synthesis of glycosaminoglycans (GAG), normalizes the metabolism of hyaline tissue, promotes the regeneration of cartilage surfaces and the articular bag. The main effects that show CS on the joint in OA: anti-inflammatory, analgesic, protective. Slowing bone resorption, reduces the loss of Ca2+ and accelerates the processes of bone repair, inhibits the progression of OA. It has analgesic effect, reduces joint pain, pain at rest and when walking, the severity of inflammation, reduces the need for non-steroidal anti-inflammatory drugs (NSAIDs). One of the representatives of medicinal products based on CS is Mucosate (ampoules 1 and 2 ml) containing 100mg of CS in 1ml. A number of studies have demonstrated the effectiveness of therapy with Mucosat in the treatment of patients with low back pain (LBP) using the 2 ml intramuscularly every other day, a course of 25 injections, as well as in the treatment of OA using the 1 ml intramuscularly every other day, starting with the 4th injection – 2 ml every other day, also a course of 25 injections. Recent developments – a new oral form of Mucosate (capsule) containing harpagophytum and the NEM® complex can serve as a supplement to the injectable course of therapy.
