Proglumetacin (usually supplied as the maleate salt) is a nonsteroidal anti-inflammatory drug (NSAID). It is a codrug (that is, a mutual prodrug) of indometacin and proglumide.[1] After oral intake, it is absorbed and metabolized to indometacin and proglumide. These two substances are then released into the system in a 1:1 molar ratio.
Indometacin contributes to the anti-inflammatory effect, while proglumide has antisecretory effects that helps prevent injury to the stomach lining.
