Sodium tolmetin dihydrate Usage And Synthesis

Chemical Properties

Crystalline Solid

Uses

beta-adrenergic blocker

Uses

Anti-inflammatory.

Definition

ChEBI: An organic sodium salt that is the dihydrate form of tolmetin sodium. Used as a nonselective nonsteroidal anti-inflammatory drug.

Biological Activity

tolmetin is a non-steroidal anti-inflammatory drug that non-selectively inhibits human cox-1 and -2 [1].the cyclooxygenase (cox) is a therapeutic target for preventing cancer. two isoforms of cox have been identified: cox 1 and cox 2. cox 1 has been constitutively expressed in most tissues and involved in mediating production of prostaglandins that control normal physiological functions, such as maintenance of the gastric mucosa and regulation of renal blood flow. cox 2 is undetectable in most normal tissues [2].

in vitro

tolmetin inhibited the activity of human cox-1 and -2 with ic50 values of 0.35 and 0.82 μm, respectively [1]. tolmetin was a competitive and reversible inhibitor of prostaglandin synthetase [3].

in vivo

in rats, pretreatment with tolmetin reduced prostaglandin synthesis by minces of renal medulla. incubation of medullary tissue with tolmetin decreased prostagland production. in anesthetized dogs, tolmetin reduced renal blood flow and shifted the distribution of renal cortical flow from the inner cortex toward the outer cortex [4].
