Flector, known generically as diclofenac epolamine, is a nonsteroidal anti-inflammatory drug (NSAID) formulated as a topical patch. It is designed to provide localized relief from pain and inflammation directly at the site of application. Flector patches are commonly prescribed for the treatment of minor strains, sprains, and contusions, offering an alternative to oral NSAIDs for patients seeking targeted pain relief with potentially fewer systemic side effects. The active ingredient, diclofenac, works by inhibiting enzymes involved in the production of prostaglandins, substances in the body that mediate pain and inflammation. By applying the patch to the skin over the affected area, Flector delivers medication directly to the tissue underneath, providing relief from pain and swelling associated with musculoskeletal injuries.
