Zio Nano Gel is a topical formulation designed for the relief of musculoskeletal pain and inflammation. It contains Diclofenac diethylamine (1.16% w/w), a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Thiocolchicoside (0.125% w/w) acts as a muscle relaxant by modulating GABAergic and glycinergic receptors, providing relief from muscle spasms. The inclusion of Linseed Oil (3.0% w/w) offers anti-inflammatory and antioxidant properties, supporting tissue repair and soothing irritated skin. Methyl Salicylate (10% w/w) serves as a counterirritant, producing a warming sensation that helps alleviate deep-seated pain by increasing local blood flow. Menthol (5% w/w) provides a cooling effect through activation of transient receptor potential (TRP) channels, contributing to analgesia and a refreshing sensation. Zio Nano Gel is indicated for the symptomatic treatment of conditions such as sprains, strains, arthritis, and other soft tissue injuries. It is intended for external use only and should be applied as directed to the affected area. The combination of anti-inflammatory, analgesic, and muscle relaxant agents in Zio Nano Gel offers a comprehensive approach to managing pain and improving mobility in patients with musculoskeletal disorders.
