Proglumetacin maleate

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 573953

CAS#: 59209-40-4 (maleate)

Description: Proglumetacin (PGM), aslo known as CR-604, Protacine and Protaxon, is a nonsteroidal anti-inflammatory drug (NSAID). It is metabolized in the body to indometacin (IND) and proglumide, a drug with antisecretory effects that helps prevent injury to the stomach lining. It was considered that the mode of action of PGM mainly depended on its active metabolite, IND. However, PGM was also active in the case of local administration into the sites of inflammation on rat hind paw edema. Therefore, it seemed that PGM had a different behavior than a so called "prodrug".
