One of the promising areas of pharmacotherapy for degenerative-dystrophic joint lesions is the use of chondroprotectors (CP), in particular chondroitin sulfate (CS). According to new Clinical Recommendations of Ministry Health (MH) of the Russian Federation (RF) «Chronic pain in patients of elderly and senile age» (2020), according to which the purpose of CS is recommended for patients older than 60 years with joint pain and contraindications to non-steroidal anti-inflammatory drugs (NSAIDs) or senile asthenia for the purpose of pain relief and the prevention of exacerbations of pain. A high level of reliability and persuasiveness of the recommendations was noted (1A) of CS use. Most of the CS is available in the form of forms for oral use, the bioavailability of which, according to clinical studies, is 13-38% due to the destruction of the CS molecules in the gastrointestinal tract. Intramuscular (i/m) administration of the drug can increase the bioavailability of CS, which can not only increase the effectiveness of therapy, but also lead to a more rapid development of the symptomatic effect. In Russia available parenteral forms of CS (Chondroguard) pharmaceutical quality, efficacy has been proven in randomized clinical trial (RCT) MH RF. To relieve pain in the joints, it is recommended to use parenteral forms of CS (Chondroguard) at a dose of 100-200 mg per day, every other day, the total duration of the course of treatment is 25-30 injections.
