Polmacoxib (trade name Acelex) is a nonsteroidal anti-inflammatory drug (NSAID) used to treat osteoarthritis. It was developed as CG100649 and approved for use in South Korea in February 2015.[1] It inhibits the enzymes carbonic anhydrase and COX-2. A study in healthy volunteers showed drug effects on urinary prostaglandin metabolites for both polmacoxib and celecoxib that suggest a similar cardiovascular risk profile.[2] Further work by this group developed dose-exposure relationsships of polmacoxib to guide clinical development strategies.[3]
