Voltaren Retard 100 mg is a prolonged-release tablet containing diclofenac sodium, a nonsteroidal anti-inflammatory drug (NSAID). It is designed to provide long-lasting relief from pain and inflammation associated with conditions such as arthritis, musculoskeletal disorders, and post-operative pain. The slow-release formulation ensures a steady absorption of the active ingredient, allowing for once-daily dosing in most cases.This medication works by inhibiting prostaglandins, substances in the body responsible for pain, swelling, and inflammation. Due to its potential impact on the gastrointestinal system, heart, and kidneys, Voltaren Retard should be used with caution, especially in individuals with a history of ulcers, cardiovascular diseases, or kidney impairment.
