Lyser D Nanotech Gel is a topical analgesic formulation combining Diclofenac (10mg), Methyl Salicylate (50mg), and Menthol (150mg) designed for the relief of musculoskeletal pain and inflammation. Diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), acts by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Methyl Salicylate serves as a counterirritant, producing a warming sensation that helps to alleviate discomfort by distracting from deeper musculoskeletal pain. Menthol provides a cooling effect through activation of transient receptor potential (TRP) channels, contributing to analgesia and enhanced patient comfort. The nanotechnology-based gel formulation facilitates improved dermal penetration and bioavailability of active ingredients, ensuring rapid onset of action and sustained relief. Lyser D Nanotech Gel is indicated for the symptomatic treatment of acute and chronic conditions such as arthritis, sprains, strains, and back pain. It is intended for external use only and should be applied to intact skin, avoiding contact with mucous membranes or broken skin. Patients are advised to follow recommended dosage and consult healthcare professionals if symptoms persist or worsen. This combination therapy offers a multimodal approach to pain management, optimizing efficacy while minimizing systemic exposure.
