Lubricart-D Tablet is a combination pharmaceutical formulation containing Glucosamine sulfate 750 mg, Diacerein 50 mg, and Methyl Sulfonyl Methane (MSM) 250 mg, designed to support joint health and alleviate symptoms associated with osteoarthritis and other degenerative joint disorders. Glucosamine is a naturally occurring amino sugar that plays a critical role in the biosynthesis of glycosaminoglycans and proteoglycans, essential components of cartilage matrix, thereby aiding in cartilage repair and maintenance. Diacerein, an anthraquinone derivative, exhibits anti-inflammatory and chondroprotective properties by inhibiting interleukin-1 beta, a pro-inflammatory cytokine implicated in cartilage degradation. Methyl Sulfonyl Methane (MSM) is an organosulfur compound known for its antioxidant and anti-inflammatory effects, contributing to the reduction of joint pain and swelling. Together, these active ingredients synergistically improve joint function, reduce pain, and slow the progression of cartilage damage. Lubricart-D is indicated for patients with mild to moderate osteoarthritis and other joint disorders requiring symptomatic relief and structural support. It should be used under medical supervision, considering potential contraindications and drug interactions. Regular monitoring is advised to assess therapeutic response and tolerability.
