Zeldinac Nano Gel is a topical analgesic formulation containing Diclofenac diethylamine (10mg), Methyl Salicylate (150mg), Menthol (50mg), and Alcohol (50mg) designed for the relief of musculoskeletal pain and inflammation. Diclofenac diethylamine, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Methyl salicylate acts as a counterirritant, producing a warming sensation that helps alleviate discomfort by distracting from underlying pain. Menthol provides a cooling effect that soothes irritated tissues and enhances local blood circulation, promoting faster recovery. The inclusion of alcohol facilitates rapid absorption of the active ingredients through the skin, ensuring prompt onset of action. Zeldinac Nano Gel is indicated for the symptomatic treatment of conditions such as arthritis, sprains, strains, and other soft tissue injuries. It is intended for external use only and should be applied to the affected area in a thin layer, avoiding broken or irritated skin. Patients should adhere to recommended dosage instructions and consult a healthcare professional if symptoms persist or worsen. This combination therapy offers a multi-modal approach to pain management, combining anti-inflammatory, analgesic, and counterirritant effects in a convenient topical gel formulation.
