FRCA Notes


Meloxicam


  • An 'oxicam' demonstrating preferential (but not exclusive) COX-2 inhibition
  • Limited, preferential selectivity for COX-2; 3 - 50x more potent against COX-2 than COX-1
  • Available as tablets and suppositories with a daily dose of 7.5mg - 15mg
  • Slow absorption albeit 90% oral bioavailability
  • 99% protein bound to albumin
  • Metabolised in the liver to inactive metabolites
  • Elimination half-life 20hrs
  • Excreted equally in urine (50%) and bile (50%)

  • Reduced GI side-effects vs. diclofenac (diclofenac itself has reduced GI side-effects vs. indomethacin and aspirin)
  • Equivalent renal side-effect profile as other NSAIDs
