Tolmetin

2-[1-methyl-5-(4-methylbenzoyl)-1H-pyrrol-2-yl]acetic acid

C15H15NO3 (257.1052)


Tolmetin is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory agent (anti-inflammatory agents, NON-steroidal) similar in mode of action to indomethacin. [PubChem]The mode of action of tolmetin is not known. However, studies in laboratory animals and man have demonstrated that the anti-inflammatory action of tolmetin is not due to pituitary-adrenal stimulation. Tolmetin inhibits prostaglandin synthetase in vitro and lowers the plasma level of prostaglandin E in man. This reduction in prostaglandin synthesis may be responsible for the anti-inflammatory action. Tolmetin does not appear to alter the course of the underlying disease in man.
