Mechanism of action

HKT-500 is a transdermal patch formulation of ketoprofen designed to deliver the NSAID directly through the skin to target localized pain and inflammation. By inhibiting COX-1 and COX-2 enzymes, ketoprofen reduces prostaglandin production, which mediates inflammatory responses and pain signaling. The topical patch formulation aims to minimize systemic exposure and associated gastrointestinal and cardiovascular risks associated with oral NSAIDs.
