Instaflex Nano Gel is a topical formulation containing Diclofenac (1.16% w/w), Linseed Oil (3% w/w), Menthol (5% w/w), and Methyl Salicylate (10% w/w), designed for the relief of musculoskeletal pain and inflammation. Diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Linseed Oil, rich in omega-3 fatty acids, contributes to anti-inflammatory effects and supports joint health. Menthol provides a cooling sensation that helps alleviate discomfort through counter-irritation, while Methyl Salicylate acts as a topical analgesic with rubefacient properties, enhancing local blood flow and further reducing pain. Instaflex Nano Gel is indicated for the symptomatic treatment of conditions such as osteoarthritis, rheumatoid arthritis, muscle strains, sprains, and other soft tissue injuries. The nano-gel formulation facilitates rapid absorption and targeted delivery of active ingredients to affected tissues, optimizing therapeutic efficacy while minimizing systemic exposure. It is intended for external use only and should be applied as directed to intact skin. Patients should avoid contact with eyes, mucous membranes, and broken skin. Use with caution in individuals with known hypersensitivity to any component. Instaflex Nano Gel offers a multi-mechanistic approach to pain management, combining anti-inflammatory, analgesic, and soothing effects in a convenient topical preparation.
