Orthomac Gel is a topical analgesic formulation containing Diclofenac diethylamine (1.16% w/w), Linseed Oil (3% w/w), Methyl Salicylate (10% w/w), and Menthol (5% w/w). This combination is designed to provide effective relief from musculoskeletal pain and inflammation associated with conditions such as arthritis, sprains, strains, and other soft tissue injuries. Diclofenac diethylamine, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Linseed Oil contributes anti-inflammatory properties and supports skin hydration. Methyl Salicylate acts as a counterirritant, producing a warming sensation that helps to alleviate pain by stimulating sensory receptors. Menthol provides a cooling effect that soothes discomfort and enhances local blood flow. Orthomac Gel is intended for topical application to the affected area, allowing targeted action with minimal systemic absorption. It is suitable for adults and should be used as directed to avoid adverse reactions such as skin irritation or hypersensitivity. This formulation offers a multi-mechanistic approach to pain management, combining anti-inflammatory, analgesic, and counterirritant effects to improve patient comfort and mobility.
