Diclofenac Diethylamine + Linseed Oil + Methyl Salicylate + MentholThird Party Manufacturing in India

This topical pain-relief gel works through a synergistic combination of four active ingredients that target pain, inflammation, and muscle stiffness via complementary pathways. Diclofenac diethylamine is a non-steroidal anti-inflammatory drug (NSAID) that acts by inhibiting the cyclooxygenase (COX-1 and COX-2) enzymes. This inhibition suppresses the synthesis of prostaglandins, which are key chemical mediators of pain and inflammation in damaged musculoskeletal tissues. Linseed oil (flaxseed oil) is rich in alpha-linolenic acid, an essential omega-3 fatty acid. It acts as an anti-inflammatory agent, helping to reduce joint swelling and improve skin penetration of the active ingredients. Methyl salicylate acts as a counter-irritant and rubefacient; when applied to the skin, it causes local vasodilation and induces a mild sensory distraction. This stimulates blood flow, producing a warming sensation that alleviates deep muscle aches and joint pain. Menthol functions by activating TRPM8 receptors in the skin, which generates a cooling sensation. This cooling effect acts as a local anesthetic, desensitizing nociceptive nerve endings and providing immediate soothing relief. Together, these ingredients combine localized anti-inflammatory action with cooling and warming counter-irritation to block pain transmission, enhance local blood circulation, and accelerate recovery in affected muscles and joints.

It is highly popular among orthopaedic specialists, general practitioners, and sports physiotherapists, ensuring stable and strong year-round market demand.

For third party manufacturing in India, this gel represents a highly stable, high-margin formulation. The manufacturing process involves creating a stable emulsion (emulgel) to ensure that the lipophilic linseed oil, methyl salicylate, and menthol are uniformly dispersed alongside the diclofenac diethylamine. Partnering with WHO-GMP certified facilities that have specialized emulgel manufacturing lines ensures consistent viscosity, smooth application, and long-term shelf-life stability. This combination is highly attractive to PCD franchise distributors, healthcare brands, and export agencies seeking a blockbuster pain-relief product.
