The active substance of Cartexan, sodium chondroitin sulfate, is a substance that occurs naturally in the human body. It is one of the structural elements of joint cartilage.
Cartexan is used for the symptomatic treatment of osteoarthritis of the knee and hip joints. The drug is characterized by a slow onset of action, which occurs within 6 to 8 weeks, therefore, for the treatment of acute and short-term pain, it is recommended to use other medications. The effects of treatment usually last for 2 to 3 months after discontinuation of treatment.
